6.4 Sentence Correction, Redundancy, and Idiomatic Usage

Key Takeaways Explain This Topic AI

The three criteria rank strictly: grammar outranks meaning, meaning outranks conciseness — the shortest option wins only when the survivors are equally correct and say the same thing.

In a sentence-improvement item the first option reproduces the underlined words exactly, so it is a real answer; never invent a fault just because the item exists.

Read the first two or three words of every option stacked vertically — the point where they first diverge is the split the item is testing, and settling it kills two or three options at once.

Passive voice is not an error: it is the better choice when the doer is unknown, irrelevant, or obvious, or when the writing is scientific or procedural.

'Despite of', 'comprised of', 'more superior than', 'the reason is because' and 'irregardless' are hybrids — each splices two correct structures into one wrong one.

6.4 Sentence Correction, Redundancy, and Idiomatic Usage

Sections 6.1 to 6.3 taught you to name a fault. Sentence-improvement items ask for something harder: choosing between four versions of one idea when two or three of them are already grammatical. The winner is decided by meaning and economy, not by grammar alone.

How a sentence-improvement item is built

A single sentence appears with part of it underlined (on a computer-based screen, highlighted). Four options follow. Four structural facts govern the format:

The first option reproduces the underlined words exactly. It is a real answer. Choose it whenever the original is already the best version — never manufacture a fault just because the item exists.

Only the underlined stretch may change. Words outside it are frozen, and every option must still fit them. An option that repairs the underline but clashes with the frozen remainder is dead.

Options often trade one fault for another. A choice that removes a wordy phrase while quietly changing some to all has failed.

Length is a tiebreaker, not a test. The shortest option wins only when the survivors are equally correct and mean the same thing.

The three criteria, in priority order

Rank Criterion The question you ask Overrides
1 Grammatical Does anything in this version break a rule of standard written English? everything

2 Meaning-preserving Does it still assert exactly what the original asserted, with the same certainty and scope? conciseness

3 Concise Does it say that in the fewest words that keep it clear and natural? nothing

The order is not decoration. A candidate who reaches for the shortest option first will sooner or later pick a crisp but ungrammatical phrase over a slightly longer correct one.

A six-step elimination routine

Read the entire sentence, frozen part included.

Predict the repair in your head before your eyes touch the options.

Read only the first two or three words of each option, stacked vertically. Where the options first diverge is the decision the item is testing — the split .

Settle the split and kill options in batches . Two or three usually die at once.

Find the next split among the survivors and repeat.

Substitute the survivor back into the full sentence and read it whole, aloud in your head. Sentence: Aldrin ...[ insisted to recheck the totals himself ]... before signing.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ underlined stretch

1 insisted to recheck ... <- the original, repeated word for word
2 insisted on rechecking ... | split 1: "to" + verb vs "on" + -ing
3 insisted on rechecking ... |

4 insisted for rechecking ...

"Insist" takes "on" plus an -ing form, so split 1 kills options 1 and 4
together, before the rest of their words are read. Options 2 and 3 are
still identical here; a later split -- "the totals himself" against

"the totals all by himself" -- separates them on economy alone.

Wordiness and redundancy

Redundancy is saying one thing twice; wordiness is using six words where two will do. Both are faults of economy rather than of grammar, which is why they survive a reader who is checking only for broken rules.

Redundant expression Why it repeats itself Write instead
advance planning planning is always in advance planning
past history history is always past history
repeat again re- already means again repeat
revert back re- already means back revert
sum total the two words are the same idea total
end result a result comes at the end result
basic fundamentals fundamentals are basic fundamentals
close proximity proximity is closeness proximity
free gift a gift is unpaid for gift
unexpected surprise a surprise is unexpected surprise
new innovation an innovation is new innovation
join together / merge together togetherness is inside the verb join / merge
ascend up / descend down direction is inside the verb ascend / descend
completely eliminate elimination is complete eliminate
small in size, red in colour the category word adds nothing small, red
each and every one word does the work every
true facts a fact is true facts
12 midnight, PIN number, ATM machine the noun is already in the acronym or term midnight, PIN, ATM

Bloated phrase Tight replacement
due to the fact that / owing to the fact that because
in spite of the fact that although
in the event that if
at this point in time / at the present time now
in order to / for the purpose of to
has the ability to / is able to can
make a decision decide
give consideration to consider
conduct an investigation of investigate

during the course of during
with regard to / in relation to about
in the vicinity of near
prior to / subsequent to before / after
a large number of many
the majority of most
on a daily basis daily
in a careful manner carefully
there is a need for the school to the school must

One pattern deserves its own line: "The reason ... is because" doubles the causal link. Write The reason the ferry was delayed is that the pier was flooded , or simply The ferry was delayed because the pier was flooded .

Passive voice — and when it is right

Passive voice puts the receiver of the action in the subject slot: The report was submitted by the treasurer. It is not an error. It becomes a fault only when the doer is known, important, and available to be the subject; then it adds two words and buries the actor.

Passive is the better choice when:

the doer is unknown — The tarpaulin was torn down overnight.

the doer is irrelevant or obvious — The application will be processed within five working days.

the receiver is the real topic of the paragraph — The Pasig River was declared biologically dead in the 1990s.

the writing is scientific or procedural, where the method matters and the person carrying it out does not — The mixture was heated for ten minutes and then filtered.

So never eliminate an option purely for being passive. Eliminate it for being passive without a reason .

Idiomatic prepositions

English idiom is arbitrary: the right preposition after a given verb or adjective is a fact to be memorised, not derived.

Word Correct pairing Example
capable of + -ing capable of leading a team
different from different from the earlier draft
prefer X to Y prefers arroz caldo to lugaw
superior / inferior to (never than , never more ) superior to last year's model
comply with comply with the dress code
consist of consists of nine members
comprise no preposition the board comprises nine members
accuse someone of accused of tampering with records
prohibit someone from + -ing prohibited from entering the lab
forbid someone to + verb forbade her to enter
insist on + -ing, or that + clause insisted on rechecking the totals

concerned about (worried) / with (dealing with) concerned about the flooding; a chapter concerned with rainfall

agree with a person, to a proposal, on a matter agreed with Nanay; agreed to the terms
result in an outcome, from a cause delays resulted in extra cost
participate in participated in the debate
succeed in + -ing succeeded in raising the funds
substitute X for Y substituted margarine for butter
blame someone for , or something on someone blamed the cashier for the shortfall
responsible for responsible for encoding the grades
oblivious to / of oblivious to the noise
identical to / with identical to the original
in contrast to / with in contrast to the 2023 figures

A second list matters just as much — verbs that take no preposition at all: discuss , emphasise , stress , mention , approach , resemble , lack , enter , answer , reach , and attend (an event). Attend to exists but means "to care for", so attend to the seminar is wrong while attend to the patient is right.

Hybrid forms, localisms, double negatives, and register

Hybrids splice two correct structures into one wrong one: despite of (from despite + in spite of ), comprised of (from comprises + composed of ), the reason is because , more superior than , could of (a mishearing of could have ), and irregardless (from irrespective + regardless ).

Localisms heard daily in the Philippines but marked wrong in standard written English: cope up with → cope with ; result to → result in ; based from → based on ; discuss about → discuss ; fill up the form → fill out the form ; open the light → turn on the light .

Double negatives. Hardly , scarcely , barely and rarely are already negative, so didn't hardly , can't scarcely and without hardly are doubled. So is couldn't find nothing .

Register and diction. Entrance-test English is formal written English. Kids becomes children , a lot of becomes many , sort of becomes somewhat , anyways becomes anyway , and contractions such as doesn't are usually avoided in the polished version.

Two annotated rewrites

Rewrite 1 (40 words to 15).

Original: Due to the fact that the barangay officials were not in agreement with each other about the new curfew, a final decision regarding the matter was not able to be arrived at by the council at this point in time.

Defect Repair
Due to the fact that — six words for one Because
were not in agreement with each other — a noun phrase doing a verb's job disagreed
regarding the matter — the matter is the curfew, already named delete

a final decision ... was not able to be arrived at by the council — passive with the real actor pushed to the end the council could not decide

at this point in time yet

Rewrite: Because the barangay officials disagreed about the new curfew, the council could not yet decide.

Rewrite 2 (31 words to 19, five distinct faults).

Original: Despite of the fact that she was more superior than her classmates in mathematics, Liwayway didn't hardly ever participate to the review sessions that were conducted by the department every Saturday.

Defect Repair
Despite of — hybrid of despite and in spite of ; the fact that is padding Although
more superior than — superior is already comparative and takes to superior to
didn't hardly ever — double negative hardly ever
participate to — wrong idiomatic preposition participated in

sessions that were conducted by the department — a passive relative clause where a possessive is shorter the department's ... sessions

Rewrite: Although she was superior to her classmates in mathematics, Liwayway hardly ever participated in the department's Saturday review sessions.

What examiners are really testing

The lure of brevity. A clipped option that has quietly dropped a necessary word is among the most effective distractors in this item type.

The silent meaning change. Watch for most becoming all , suggests becoming proves , may becoming will .

The half-repair. The option fixes the obvious redundancy and introduces a preposition error four words later. Read every option to its final word.

The unearned rejection of the original. Some sentences are already right.

Fixing outside the underline. If the fault you spotted is in the frozen text, you have misread the item.
