Conciseness and Redundancy

Knowledge of Language  · Topic 2.1

Introduction

The ACT's most common correct answer in the Style and Tone section is OMIT. Learning to love deletion — rather than fearing it — is the single fastest way to improve your English score.

Conciseness questions appear on every ACT English passage, often 4–6 times. They are the most learnable question type in the Production of Writing category because the rule is simple: if a word or phrase adds no new information, it must go.

By the end of this lesson you will be able to:

'The two twins, who were both siblings to each other, collaborated together on the joint project.' Count the redundancies. There are at least four. After this lesson, you will spot all of them in under 5 seconds.

The Concept

The Core Rule

Every word in an ACT-correct sentence must earn its place. Redundancy occurs when a word or phrase repeats information already conveyed — explicitly or by definition — elsewhere in the sentence. On the ACT, the shortest answer that preserves the full meaning is almost always correct.

How the ACT tests this

  • Underlines a phrase that restates information already present in the sentence (e.g., 'future plans' — plans are always future; 'past history' — history is always past)
  • Offers OMIT or a shorter version as one answer choice alongside longer, wordy alternatives — the correct answer is the most concise version that loses no meaning
  • Tests verbose phrases that can be replaced by a single word: 'at this point in time' → 'now'; 'due to the fact that' → 'because'; 'in the event that' → 'if'

Definitional Redundancy

Some words are redundant by definition because the modifier repeats what the noun already means. The ACT tests these patterns repeatedly.

  • 'Past history' — history is always past. Drop 'past.'
  • 'Future plans' — plans are always for the future. Drop 'future.'
  • 'End result' — a result is an end state. Drop 'end.'
  • 'Free gift' — a gift is free by definition. Drop 'free.'
  • 'Advance warning' — a warning comes before the event. Drop 'advance.'
  • 'Completely unanimous' — unanimous already means all in agreement. Drop 'completely.'

Phrase-Level Redundancy

Some phrases repeat the same idea using different words without adding meaning. These are often colloquialisms that slip into formal writing.

  • 'Each and every' → 'each' or 'every' (not both)
  • 'First and foremost' → 'first'
  • 'Collaborated together' → 'collaborated' ('together' is implicit in 'collaborate')
  • 'Returned back' → 'returned' ('back' is implicit in 'returned')
  • 'Combine together' → 'combined'
  • 'Repeat again' → 'repeat'

Verbose Circumlocutions

Circumlocutions replace a single direct word with a roundabout phrase. On the ACT, these are always wrong when a direct word is available in the answer choices.

  • 'Due to the fact that' → 'because'
  • 'At this point in time' → 'now'
  • 'In the event that' → 'if'
  • 'In spite of the fact that' → 'although'
  • 'For the purpose of' → 'to'
  • 'Made a decision to' → 'decided to'

Contextual Redundancy — Information Already in the Passage

Sometimes the redundancy is not within a single phrase but between the underlined portion and information stated elsewhere in the sentence or paragraph. This is the hardest type to spot.

  • If the passage already states the subject is a biologist, adding 'who studies living organisms' in a later sentence is redundant.
  • If the passage establishes the setting is Paris in the opening sentence, a later underlined phrase 'in the French capital city of Paris' is redundant.
  • Always read the surrounding context before evaluating whether a phrase is genuinely new information or a restatement.

Your strategy

  1. Step 1 — Read the entire sentence before evaluating the underlined portion. Ask: is the information in the underlined phrase already expressed somewhere else in the sentence or recent passage?
  2. Step 2 — Apply the OMIT test: remove the underlined portion mentally. If the sentence still means the same thing and loses no unique information, OMIT is correct.
  3. Step 3 — Check whether the underlined phrase is a verbose circumlocution with a shorter equivalent in the answer choices. The shortest accurate replacement is almost always right.
  4. Step 4 — Do not mistake brevity for incompleteness. The ACT credits the answer that is shortest without losing meaning — not the longest answer that adds more context.

Worked Examples

Easy Example 1 Partial Redundancy Trap — Option B Removes One Adverb But Keeps 'ultimately,' Which Still Repeats The Finality Already Expressed By 'final Decision.' Students Who Eliminate Only The More Obvious Redundancy Fall For This.
The committee's final decision was [ultimately and conclusively determined] after three weeks of deliberation. All twelve members voted unanimously in favor of the proposal, and the chair signed the resolution that same evening.

Which choice most effectively improves the sentence by eliminating redundancy?

  • A. NO CHANGE
  • B. ultimately determined
  • C. determined (Correct answer)
  • D. conclusively and finally determined
Step 1

Identify the underlined phrase: 'ultimately and conclusively determined.' The noun is 'decision' — a final decision is already conclusive and ultimate by definition.

Step 2

Additionally, 'final decision' at the start of the sentence already conveys finality — 'ultimately,' 'conclusively,' and 'final' all repeat the same idea.

Step 3

'Determined' alone carries the full meaning: the committee determined its decision. All modifiers are redundant.

Step 4

Option C is the most concise and loses no meaning from the original sentence.

Correct answer: C

Why C is correct

Correct — 'determined' alone conveys the action; all modifiers are redundant given 'final decision.'

Why other options are wrong

A: Two redundant adverbs ('ultimately' and 'conclusively') with a verb — both are implied by 'final decision' earlier in the sentence.

B: Still includes 'ultimately,' which is redundant with 'final decision.'

D: Adds 'finally' — a third redundant modifier on top of two already present.

⚠ Trap: Partial redundancy trap — option B removes one adverb but keeps 'ultimately,' which still repeats the finality already expressed by 'final decision.' Students who eliminate only the more obvious redundancy fall for this.

Medium Example 2 Over-deletion Trap — Option D Removes Too Much. 'Natural' Is Not Redundant With The Surrounding Context (the Passage Is About The Wild Vs. Captivity Contrast) — Students Who Apply OMIT Too Aggressively Pick D Over The More Precise C.
The documentary filmmaker spent eighteen months traveling across three continents to capture footage of endangered species in their [natural, native habitats where they naturally live]. Her film premiered at a major international festival and won three awards.

Which choice best improves the passage by eliminating redundancy?

  • A. NO CHANGE
  • B. natural and native habitats
  • C. natural habitats (Correct answer)
  • D. habitats
Step 1

Examine 'natural, native habitats where they naturally live.' Break it down: 'natural habitats' is the standard phrase for where animals live in the wild.

Step 2

'Native' means originating in — for animals, native habitat and natural habitat are the same concept. Redundant.

Step 3

'Where they naturally live' restates 'natural habitats' entirely. Redundant.

Step 4

'Natural habitats' (C) is the standard, precise term — 'native' and 'where they naturally live' are both redundant with it.

Correct answer: C

Why C is correct

Correct — 'natural habitats' is the precise term; 'native' adds nothing new.

Why other options are wrong

A: Three redundant elements: 'natural,' 'native,' and 'where they naturally live' all say the same thing.

B: Removes 'where they naturally live' but keeps the 'natural and native' redundancy — still a 50% fix.

D: Technically non-redundant, but removes 'natural' which carries meaningful content (distinguishes from, say, a zoo or lab). 'Habitats' alone is less precise than 'natural habitats.'

⚠ Trap: Over-deletion trap — option D removes too much. 'Natural' is not redundant with the surrounding context (the passage is about the wild vs. captivity contrast) — students who apply OMIT too aggressively pick D over the more precise C.

Hard Example 3 False Equivalence Trap — Options A, B, And D All Use Different Wordy Phrases That Mean 'because,' Making Them Look Like Distinct Choices. Students May Pick The One That 'sounds Best' Rather Than Recognizing All Three Are Verbose And Only C Is Concise.
Urban heat islands form [due to the fact that] dark surfaces like asphalt and rooftops absorb solar radiation and release it as heat. Cities can be several degrees warmer than surrounding rural areas, creating public health challenges during summer heat events.

Which choice best improves the passage?

  • A. NO CHANGE
  • B. on account of the fact that
  • C. because (Correct answer)
  • D. as a result of the fact that
Step 1

Identify the underlined phrase: 'due to the fact that' — a classic verbose circumlocution.

Step 2

Ask: what single word expresses the same logical relationship? 'Because' introduces a causal clause and is exactly equivalent.

Step 3

Options B and D are equally verbose circumlocutions — 'on account of the fact that' and 'as a result of the fact that' are not improvements.

Step 4

'Because' (C) is the direct, concise replacement — no meaning is lost.

Correct answer: C

Why C is correct

Correct — 'because' is the direct causal conjunction; all other words are verbal filler.

Why other options are wrong

A: 'Due to the fact that' — six words where one suffices.

B: 'On account of the fact that' — even longer than the original. Wrong direction.

D: 'As a result of the fact that' — another circumlocution, as wordy as A.

⚠ Trap: False equivalence trap — options A, B, and D all use different wordy phrases that mean 'because,' making them look like distinct choices. Students may pick the one that 'sounds best' rather than recognizing all three are verbose and only C is concise.

Strategy Tips

  • When OMIT is an answer choice, test it first. Remove the underlined portion and read the sentence. If it is still complete and clear, OMIT is almost certainly correct.
  • Memorize the ten most common verbose circumlocutions and their single-word replacements: 'due to the fact that' → because, 'at this point in time' → now, 'in the event that' → if, 'for the purpose of' → to, 'in spite of the fact that' → although.
  • For redundancy within a phrase, ask: 'Does this modifier add any information not already contained in the noun or the surrounding sentence?' If not, it is redundant.
  • Do not confuse conciseness with incompleteness. The correct answer must preserve all meaning — 'determined' is correct only if 'final decision' already establishes finality.

Common pitfalls

Over-deletion: removing a word that carries unique meaning not expressed elsewhere in the sentence. Always verify that OMIT truly preserves all the sentence's information before choosing it.

Mistaking style for redundancy: 'She carefully and methodically organized the files' — 'carefully' and 'methodically' overlap but are not identical. The ACT would not call this redundant unless one were explicitly restated by the other.

Ignoring context: a phrase that is redundant given one part of the passage may be necessary if that part is reworded. Always read the full sentence before judging redundancy.

Conciseness questions are among the fastest on the exam — 15–20 seconds each. The shortest complete answer is correct in roughly 80% of cases. If you are spending more than 25 seconds, you are overthinking it.

Summary

  • Every word must add new information — definitional redundancies (past history, free gift), phrase-level repetitions (collaborated together), and verbose circumlocutions (due to the fact that) are all wrong on the ACT.
  • OMIT is correct when removing the underlined portion leaves the sentence complete and no meaning is lost — test OMIT first whenever it appears as a choice.
  • The shortest accurate answer is almost always right, but do not over-delete — ensure that the remaining sentence is still complete and precise.

Take any three paragraphs from a textbook. Highlight every circumlocution, definitional redundancy, and phrase-level repetition you can find. Rewrite each paragraph to be as concise as possible without losing any meaning. Count how many words you cut — aim for a 15–25% reduction.
