Concision

A complete ACT guide to Concision — covering key concepts, exam-focused explanations, and high-yield FAQs.

Overview

Concision is one of the most frequently tested concepts on the ACT English section, appearing in approximately 10-15% of all questions. This rhetorical skill tests a student's ability to identify and eliminate unnecessary words, phrases, and redundancies while preserving the intended meaning of a sentence. The ACT rewards writers who can express ideas clearly and efficiently, making concision a cornerstone of effective writing and a high-yield topic for test preparation.

Understanding ACT concision goes beyond simply choosing the shortest answer. Students must learn to distinguish between necessary detail that adds meaning and superfluous language that clutters communication. The test frequently presents four answer choices where one option expresses an idea most directly without sacrificing clarity or grammatical correctness. Mastering this skill requires developing an ear for wordiness and recognizing common patterns of redundancy that appear throughout the exam.

Concision connects intimately with other rhetorical skills tested on the ACT, including word choice, style, and tone. It also intersects with grammar concepts such as modifier placement and parallel structure, since wordy constructions often introduce grammatical errors. Students who excel at concision questions demonstrate not only technical writing proficiency but also the critical thinking skills necessary to evaluate whether additional words genuinely enhance meaning or merely add bulk. This topic serves as a foundation for effective communication in academic writing, professional correspondence, and everyday expression.

Learning Objectives

  • [ ] Identify when Concision is being tested in ACT English questions
  • [ ] Explain the core rule or strategy behind Concision
  • [ ] Apply Concision to ACT-style questions accurately
  • [ ] Distinguish between necessary detail and redundant information
  • [ ] Recognize common redundancy patterns that appear on the ACT
  • [ ] Evaluate answer choices to select the most concise option without losing meaning
  • [ ] Identify when "OMIT the underlined portion" is the correct answer

Prerequisites

  • Basic sentence structure: Understanding subjects, verbs, and objects helps identify which words are essential versus expendable in a sentence
  • Parts of speech: Recognizing nouns, verbs, adjectives, and adverbs enables students to spot redundant modifiers and unnecessary descriptors
  • Reading comprehension: The ability to understand a passage's meaning is crucial for determining whether removing words changes the intended message
  • Grammar fundamentals: Knowledge of complete sentences and clauses helps distinguish between concise writing and fragments

Why This Topic Matters

Concision represents a fundamental principle of effective communication that extends far beyond standardized testing. In professional settings, concise writing saves time, reduces confusion, and demonstrates respect for readers' attention. Academic writing values precision and economy of language, skills that directly transfer from ACT preparation to college essays and research papers. The ability to express complex ideas efficiently is a hallmark of sophisticated thinking and clear communication.

On the ACT English section, concision questions appear with remarkable frequency—students can expect to encounter 6-10 such questions on a typical test. These questions often appear as "DELETE" or "OMIT" options, where one answer choice suggests removing the underlined portion entirely. Concision also manifests in questions where all four options are grammatically correct, but only one expresses the idea most efficiently. The ACT specifically tests whether students can identify redundancies, eliminate wordy phrases, and choose direct expressions over verbose alternatives.

Common manifestations of concision testing include: redundant pairs (such as "past history" or "future plans"), wordy prepositional phrases that could be replaced with single words, unnecessary intensifiers and qualifiers, repetitive information already stated elsewhere in the passage, and inflated verb phrases that could be simplified. The test also frequently presents situations where additional examples or explanations add no new information, making deletion the best choice. Recognizing these patterns dramatically improves both speed and accuracy on test day.

Core Concepts

The Fundamental Principle of Concision

The core principle of concision is straightforward: express ideas using the fewest words necessary while maintaining clarity and grammatical correctness. This does not mean always choosing the shortest answer—it means eliminating words that contribute nothing to meaning. The ACT tests whether students can identify when additional words serve a purpose (adding specificity, clarity, or necessary detail) versus when they merely inflate word count without enhancing communication.

Three criteria must be satisfied for an answer to be considered optimally concise:

  1. Completeness: The answer must express the full intended meaning
  2. Clarity: The answer must be immediately understandable to readers
  3. Efficiency: The answer must use no more words than necessary to achieve completeness and clarity

When evaluating answer choices, students should ask: "Does this word or phrase add new information or meaning?" If the answer is no, the word or phrase should be eliminated.

Redundancy: The Primary Enemy of Concision

Redundancy occurs when words or phrases repeat information already conveyed, either within the same expression or elsewhere in the sentence or passage. The ACT frequently tests students' ability to recognize and eliminate various types of redundancy:

Redundancy TypeExampleConcise VersionExplanation
Adjective-NounPast historyHistoryHistory already refers to the past
Verb-AdverbCompletely eliminateEliminateEliminate already means complete removal
PrepositionalThe reason why is becauseThe reason is / BecauseBoth "reason" and "because" indicate causation
ContextualIn the year 1776, the Declaration was signed in 1776In 1776, the Declaration was signedThe year appears twice
DefinitionalA beginner who is just starting outA beginnerBeginners by definition are just starting

Recognizing these patterns enables rapid identification of concision questions and efficient elimination of incorrect answers.

Wordy Phrases and Their Concise Alternatives

The ACT repeatedly tests common wordy constructions that can be replaced with simpler alternatives. Memorizing these patterns provides immediate recognition on test day:

Common Wordy Phrases:

  • "Due to the fact that" → "Because"
  • "In spite of the fact that" → "Although" or "Despite"
  • "At this point in time" → "Now" or "Currently"
  • "In the event that" → "If"
  • "For the purpose of" → "To"
  • "In order to" → "To"
  • "Has the ability to" → "Can"
  • "Is able to" → "Can"
  • "Make a decision" → "Decide"
  • "Come to a conclusion" → "Conclude"
  • "Take into consideration" → "Consider"
  • "Give consideration to" → "Consider"

These inflated phrases appear frequently in ACT passages, and recognizing them immediately signals a concision question.

The "OMIT" Option Strategy

One of the most distinctive features of ACT concision questions is the "OMIT the underlined portion" answer choice, typically appearing as option F, G, J, or H depending on question numbering. This option tests whether the underlined portion adds any value to the passage. Students often hesitate to choose OMIT, fearing they're removing important information, but this option is correct approximately 20-25% of the time it appears.

When to choose OMIT:

  • The underlined portion repeats information stated elsewhere in the sentence or paragraph
  • The underlined portion provides examples that don't add clarity or specificity
  • The underlined portion contains transition words or phrases that don't improve flow
  • The underlined portion includes intensifiers or qualifiers that don't change meaning
  • Removing the portion creates a grammatically complete, clear sentence

When NOT to choose OMIT:

  • Removal creates a sentence fragment or grammatical error
  • The underlined portion provides necessary context or specificity
  • The information is mentioned elsewhere but serves a different rhetorical purpose
  • The underlined portion contains a transition that clarifies logical relationships

Necessary Detail vs. Unnecessary Elaboration

A sophisticated understanding of concision requires distinguishing between helpful detail and pointless elaboration. Not all additional words represent violations of concision—some provide valuable specificity, clarity, or emphasis. The ACT tests this nuanced understanding by presenting questions where the shortest answer might actually be too vague or unclear.

Necessary detail includes:

  • Specific examples that illustrate abstract concepts
  • Clarifying information that prevents ambiguity
  • Technical terms that provide precision
  • Modifiers that meaningfully restrict or specify nouns
  • Transitions that clarify logical relationships between ideas

Unnecessary elaboration includes:

  • Examples that merely restate what's already clear
  • Adjectives or adverbs that don't change meaning
  • Information the reader can easily infer from context
  • Repetitive phrasing that says the same thing multiple ways
  • Tangential information unrelated to the paragraph's focus

The key distinction: necessary detail adds meaning or clarity; unnecessary elaboration adds only words.

Passive Voice and Concision

While not always incorrect, passive voice constructions often create wordiness that active voice eliminates. The ACT frequently tests whether students recognize opportunities to convert passive constructions to more concise active alternatives.

Passive (wordy): "The experiment was conducted by the scientists."

Active (concise): "The scientists conducted the experiment."

Passive (wordy): "The decision was made by the committee to postpone the vote."

Active (concise): "The committee decided to postpone the vote."

However, passive voice is sometimes necessary or preferable when the actor is unknown, unimportant, or when emphasis should fall on the action's recipient. Concision doesn't require eliminating all passive constructions—only those that unnecessarily inflate word count.

Concept Relationships

Concision serves as a central hub connecting multiple rhetorical and grammatical concepts tested on the ACT. Understanding these relationships deepens mastery and improves overall performance on the English section.

Concision → Word Choice: Selecting concise language requires choosing precise words that convey meaning efficiently. A single well-chosen word often replaces an entire phrase, making vocabulary knowledge essential for concision mastery.

Concision ← Redundancy Recognition: Identifying redundancy is the primary mechanism for achieving concision. Students must recognize when words repeat information, whether through definitional redundancy (past history), contextual redundancy (information stated elsewhere), or semantic redundancy (completely eliminate).

Concision ↔ Sentence Structure: Complex sentence structures sometimes create opportunities for concision through combination or simplification. Conversely, overly simplified sentences might require additional words for clarity, demonstrating that concision and structure must balance.

Concision → Relevance and Purpose: Many concision questions test whether additional information serves the passage's purpose. This connects concision to broader rhetorical skills questions about whether sentences should be added or deleted based on the passage's focus.

Grammar Fundamentals → Concision: Understanding complete sentences, proper modification, and parallel structure enables students to evaluate whether concise alternatives maintain grammatical correctness. A concise answer that creates a fragment or modifier error is never correct.

Concision → Tone and Style: Wordy, inflated language often creates an inappropriately formal or pompous tone, while concise expression typically sounds more natural and confident. The ACT rewards writing that sounds like clear, educated communication rather than artificial verbosity.

High-Yield Facts

The shortest answer is correct approximately 50-60% of the time on concision questions, making length a useful initial screening tool when all options are grammatically correct.

"OMIT the underlined portion" is correct about 20-25% of the time it appears as an option, significantly higher than random chance would predict.

Redundant pairs are the most frequently tested form of wordiness, including expressions like "advance planning," "end result," "past memories," and "future predictions."

Wordy prepositional phrases can almost always be replaced with single words or shorter alternatives, such as "due to the fact that" → "because."

When information appears twice in a passage—once in the underlined portion and once elsewhere—the underlined portion should typically be deleted.

  • Passive voice constructions are often (but not always) less concise than active voice alternatives.
  • Intensifiers like "very," "really," "quite," and "extremely" rarely add meaningful emphasis and usually represent unnecessary words.
  • Phrases containing "the fact that" are almost always wordy and can be simplified.
  • Questions asking whether to add or delete sentences often test concision by determining if the addition provides new, relevant information.
  • Transition words and phrases should only be included when they clarify logical relationships; otherwise, they represent unnecessary words.
  • Adjective strings (multiple adjectives modifying one noun) often contain redundancy, with some adjectives adding no additional meaning.
  • Converting noun phrases to verbs typically increases concision: "make a decision" → "decide."
  • Context determines whether detail is necessary; information obvious from surrounding sentences should be omitted.
  • Grammatical correctness always takes precedence over concision—a concise answer that creates an error is never correct.

Common Misconceptions

Misconception: The shortest answer is always correct on concision questions.

Correction: While shorter answers are frequently correct, the truly concise answer is the one that expresses the complete meaning with the fewest necessary words. Sometimes the shortest option is too vague, creates ambiguity, or omits necessary information. Students must evaluate whether shorter options maintain clarity and completeness.

Misconception: "OMIT" should be avoided because it seems like giving up or not answering the question.

Correction: "OMIT the underlined portion" is a legitimate answer choice that's correct approximately 20-25% of the time it appears. The ACT specifically includes this option to test whether students recognize when additional words add no value. Choosing OMIT when appropriate demonstrates sophisticated understanding of concision.

Misconception: All descriptive language and adjectives represent unnecessary wordiness.

Correction: Descriptive language that adds meaningful specificity, creates necessary distinction, or serves the passage's rhetorical purpose is not wordiness. Concision eliminates words that don't contribute to meaning, not words that enhance precision or clarity. The test distinguishes between helpful detail and pointless elaboration.

Misconception: Passive voice is always wrong and should always be eliminated.

Correction: While passive voice often creates wordiness, it's sometimes necessary or preferable when the actor is unknown, unimportant, or when emphasis should fall on the action's recipient. The ACT tests whether passive constructions are unnecessarily wordy in context, not whether passive voice itself is incorrect.

Misconception: Concision questions only test redundancy and wordiness.

Correction: Concision questions also test relevance, asking whether additional information serves the passage's purpose. A sentence might be internally concise but still represent unnecessary elaboration if it doesn't advance the paragraph's focus. Students must evaluate both internal wordiness and contextual relevance.

Misconception: Formal writing requires longer, more complex expressions to sound sophisticated.

Correction: Sophisticated writing is clear, precise, and efficient—not inflated or verbose. The ACT rewards natural, direct expression over artificially formal or pompous language. Phrases like "due to the fact that" don't sound more educated than "because"; they sound wordy.

Misconception: If information is interesting or well-written, it should be included even if not strictly necessary.

Correction: The ACT evaluates writing based on purpose and relevance, not entertainment value. Even interesting, well-crafted sentences should be omitted if they don't serve the passage's focus. Effective writing stays on topic and eliminates tangential information, regardless of its intrinsic interest.

Worked Examples

Example 1: Identifying and Eliminating Redundancy

Passage excerpt: "The ancient ruins, which date back to ancient times, reveal much about early civilization."

Question: Which of the following alternatives to the underlined portion would be LEAST acceptable?

  • A. NO CHANGE
  • B. ruins
  • C. old ruins
  • D. ruins from long ago

Step 1: Identify what's being tested

The question asks for the LEAST acceptable alternative, meaning we're looking for the option that creates a problem. The underlined portion contains "ancient ruins, which date back to ancient times," which immediately signals potential redundancy testing.

Step 2: Analyze the original

"Ancient ruins" already indicates these structures are from ancient times. The phrase "which date back to ancient times" repeats information already conveyed by "ancient." This is definitional redundancy—ruins that are ancient necessarily date back to ancient times.

Step 3: Evaluate each option

  • Option A (NO CHANGE): Contains obvious redundancy—"ancient" appears twice
  • Option B (ruins): Removes "ancient" entirely, which might lose important information about the ruins' age
  • Option C (old ruins): Provides age information without redundancy; "old" is less specific than "ancient" but not redundant
  • Option D (ruins from long ago): Provides age information without redundancy; "from long ago" conveys similar meaning to "ancient"

Step 4: Select the answer

The question asks for the LEAST acceptable option. Option A contains clear redundancy, making it the least acceptable. This is a reverse question where recognizing the redundancy helps identify the worst answer rather than the best.

Answer: A

Connection to learning objectives: This example demonstrates identifying when concision is tested (redundant age references), explaining the core rule (eliminate words that repeat information), and applying the strategy (recognizing definitional redundancy).

Example 2: Evaluating "OMIT" as an Option

Passage excerpt: "Marie Curie discovered radium in 1898. This groundbreaking discovery, which was a major breakthrough in science, changed our understanding of radioactivity."

Question:

  • F. NO CHANGE
  • G. discovery, which was groundbreaking,
  • H. discovery
  • J. OMIT the underlined portion

Step 1: Identify the test focus

The presence of "OMIT" signals a concision question testing whether the underlined portion adds value. We must determine if "which was a major breakthrough in science" contributes meaningful information.

Step 2: Check for redundancy

The sentence already describes the discovery as "groundbreaking" immediately before the underlined portion. "Major breakthrough in science" essentially means the same thing as "groundbreaking"—both indicate significant scientific advancement. This is contextual redundancy within the same sentence.

Step 3: Test OMIT

If we remove the underlined portion: "This groundbreaking discovery changed our understanding of radioactivity." The sentence remains grammatically complete, clear, and meaningful. No information is lost because "groundbreaking" already conveys that this was a major scientific breakthrough.

Step 4: Evaluate other options

  • Option F (NO CHANGE): Redundant with "groundbreaking"
  • Option G: Still redundant—"groundbreaking" and "groundbreaking" repeat
  • Option H: Removes the redundant phrase but keeps "discovery," which is already stated
  • Option J (OMIT): Eliminates all redundancy while maintaining clarity

Step 5: Apply the OMIT strategy

OMIT satisfies all criteria: the sentence remains grammatically correct, the meaning is preserved, and unnecessary words are eliminated. The underlined portion adds no new information beyond what "groundbreaking discovery" already conveys.

Answer: J

Connection to learning objectives: This example shows identifying concision testing (redundancy and OMIT option), explaining the strategy (eliminate contextual redundancy), and applying the rule (choosing OMIT when the underlined portion adds no value).

Exam Strategy

Approaching Concision Questions

Step 1: Identify concision questions quickly

Look for these triggers:

  • "OMIT the underlined portion" as an answer choice
  • Answer choices of dramatically different lengths
  • All options grammatically correct but varying in wordiness
  • Underlined portions containing phrases like "the fact that," "due to," "in order to"
  • Questions asking whether to add or delete sentences

Step 2: Read for redundancy first

Before evaluating answer choices, check whether the underlined portion:

  • Repeats information stated elsewhere in the sentence
  • Contains redundant pairs (past history, advance planning)
  • Includes information obvious from context
  • Uses wordy phrases with concise alternatives

Step 3: Apply the length screening test

When all options are grammatically correct, start by examining the shortest option. Ask: "Does this express the complete meaning clearly?" If yes, it's likely correct. If no, determine what necessary information is missing, then find the shortest option that includes that information.

Step 4: Don't fear OMIT

When OMIT appears, seriously consider it. Test whether removing the underlined portion:

  • Creates a grammatically complete sentence
  • Preserves all necessary meaning
  • Eliminates redundancy or irrelevant information

If all three conditions are met, OMIT is likely correct.

Step 5: Watch for necessary detail

Before selecting the most concise option, verify it doesn't sacrifice:

  • Necessary specificity or precision
  • Important context or clarification
  • Logical transitions between ideas
  • Grammatical completeness

Trigger Words and Phrases

High-probability wordiness indicators:

  • "Due to the fact that" (use "because")
  • "In spite of the fact that" (use "although" or "despite")
  • "At this point in time" (use "now")
  • "In the event that" (use "if")
  • "For the purpose of" (use "to")
  • "In order to" (use "to")
  • "The reason is because" (use "the reason is" or "because")
  • Any phrase containing "the fact that"

Redundancy red flags:

  • Adjective-noun pairs where the adjective restates the noun's definition
  • Time references that repeat (e.g., "in 1776" appearing twice)
  • Intensifiers that don't change meaning (very, really, quite)
  • Multiple examples that illustrate the same point

Process of Elimination Tips

  1. Eliminate options with obvious redundancy first: If an answer choice contains clear redundant pairs or repeats information, cross it out immediately.
  1. Eliminate the longest option if it contains wordy phrases: When you spot "due to the fact that" or similar constructions, that option is rarely correct.
  1. Keep options that add necessary specificity: If one option provides important detail that others lack, don't eliminate it just because it's longer.
  1. Compare remaining options for subtle differences: Often the choice comes down to two similar options—identify the single word or phrase that differs and determine whether it adds meaning.

Time Allocation

Concision questions should be among the fastest to answer—aim for 20-30 seconds per question once you've developed pattern recognition. These questions rarely require re-reading large portions of the passage; the sentence containing the underlined portion usually provides sufficient context. If you find yourself spending more than 45 seconds on a concision question, you're likely overthinking it. Trust your instinct about wordiness and move forward.

Exam Tip: If you're stuck between two options and both seem grammatically correct, choose the shorter one. The ACT's concision bias means the more efficient expression is correct more often than not.

Memory Techniques

The "TRIM" Mnemonic for Concision

Test for redundancy

Remove wordy phrases

Identify OMIT opportunities

Maintain necessary meaning

When approaching any concision question, mentally run through TRIM to systematically evaluate options.

The "Redundancy Radar" Visualization

Imagine a radar screen scanning for redundant words. When you encounter phrases like "past history," "advance planning," or "end result," visualize the radar pinging—these are definitional redundancies where the adjective restates what the noun already means. This mental image helps automatically flag redundancy during timed testing.

The "Because Replacement" Rule

Memorize this simple substitution: whenever you see "due to the fact that," "in light of the fact that," "owing to the fact that," or "for the reason that," mentally replace it with "because." If "because" works, the original phrase is wordy. This single rule eliminates multiple common wordiness patterns.

The "OMIT Confidence" Mantra

Many students hesitate to choose OMIT due to psychological discomfort with deletion. Develop confidence by repeating: "OMIT is right 1 in 4 times—trust the test." This reminds you that OMIT is a legitimate, frequently correct answer that deserves serious consideration.

Acronym: WORDY Phrases to Avoid

With regard to (use "regarding" or "about")

On account of (use "because")

Regardless of the fact that (use "although")

During the time that (use "while")

Yet another (often unnecessary intensifier)

This acronym helps recall common wordy constructions that signal concision questions.

Summary

Concision represents one of the highest-yield topics on the ACT English section, testing students' ability to identify and eliminate unnecessary words while preserving meaning and grammatical correctness. The fundamental principle is straightforward: express ideas using the fewest words necessary to maintain clarity and completeness. Mastery requires recognizing redundancy in its various forms—definitional redundancy (past history), contextual redundancy (information repeated elsewhere), and semantic redundancy (completely eliminate). Students must distinguish between necessary detail that adds meaning and unnecessary elaboration that merely inflates word count. The ACT frequently tests concision through "OMIT the underlined portion" options, which are correct approximately 20-25% of the time they appear, and through questions where all options are grammatically correct but vary in efficiency. Common patterns include wordy prepositional phrases replaceable with single words, redundant adjective-noun pairs, and passive voice constructions that active voice simplifies. Success requires developing pattern recognition for wordiness triggers, trusting that shorter answers are frequently correct when grammatically sound, and maintaining confidence in OMIT as a legitimate answer choice. The ability to write concisely extends beyond test performance to academic and professional communication, making this skill valuable for long-term success.

Key Takeaways

  • Concision means expressing ideas with the fewest necessary words while maintaining clarity and grammatical correctness—not simply choosing the shortest answer
  • Redundancy is the primary enemy of concision, appearing as definitional redundancy (past history), contextual redundancy (information stated elsewhere), and semantic redundancy (completely eliminate)
  • "OMIT the underlined portion" is correct approximately 20-25% of the time it appears and should be seriously considered whenever the underlined portion repeats information or adds no value
  • Common wordy phrases like "due to the fact that," "in order to," and "at this point in time" have concise alternatives ("because," "to," "now") that appear frequently on the ACT
  • The shortest answer is correct 50-60% of the time on concision questions when all options are grammatically correct, making length a useful screening tool
  • Necessary detail that adds specificity, clarity, or serves the passage's purpose should be preserved; only eliminate words that contribute nothing to meaning
  • Pattern recognition for redundancy and wordiness enables rapid identification and solution of concision questions, making them among the fastest to answer on the English section

Word Choice and Precision: Mastering concision naturally leads to studying word choice, as selecting precise vocabulary often enables more concise expression. A single well-chosen word can replace an entire phrase, making vocabulary knowledge essential for optimal concision.

Relevance and Purpose: Many concision questions overlap with rhetorical skills questions about whether sentences should be added or deleted based on the passage's focus. Understanding how to evaluate relevance deepens concision mastery.

Sentence Structure and Combining: Complex sentence structures sometimes create opportunities for concision through combination or simplification. Studying how to effectively combine sentences builds on concision principles.

Transitions and Logical Flow: Determining whether transition words and phrases are necessary or superfluous requires understanding logical relationships between ideas, connecting concision to broader organizational skills.

Style and Tone: Concise writing typically creates a more confident, natural tone than wordy alternatives. Studying how word choice affects style builds on the foundation of concision mastery.
