TOEIC Link Writing — Collocation and Word Partnership Precision: Why "make a decision" Scores and "do a decision" Does Not

A TOEIC Link writer who produces do a decision has made no grammatical error — the article is right, the noun is right, the verb is a real verb — and the rater still marks the phrasing down, because English says make a decision and never do one. The words are individually correct and the combination is wrong, and that gap between correct-parts and wrong-whole is exactly what a native reader registers instantly as non-native writing. Collocation — which words habitually partner which — is invisible when you get it right and glaring when you get it wrong.

This is one of the most underweighted levers in the writing section. Candidates study vocabulary as a list of single words with single meanings, so they can define decision, mistake, and opinion perfectly and still write do a decision, say a mistake, and tell an opinion. The rubric's vocabulary and language-use bands reward writing that reads like English, and nothing signals non-native writing faster than a word paired with the wrong partner. Fixing collocations lifts the vocabulary sub-score without learning a single new word — you already know the words; you are learning which ones hold hands. For the related discipline of choosing a strong lexical verb instead of a weak one, see the light verb and delexical construction control guide, and for precise single-word choice, see the vocabulary precision and collocation discipline guide.

Why English fixes word partnerships

Every language decides, largely by habit rather than logic, which words go together. English makes a decision but takes a decision in British usage, does homework but makes an effort, has heavy rain but strong wind. There is rarely a rule you can derive from meaning — heavy rain and strong wind describe the same intensity, yet the adjectives are not interchangeable. These pairings are stored, not computed: native writers do not reason to make a decision; they retrieve it whole, and any other pairing sounds wrong the instant it appears.

This is why collocation errors are so costly relative to their size. A single mispaired word does not obscure meaning — the reader understands do a decision perfectly — but it breaks the surface that fluent writing maintains, and on a rubric that scores how native-like the language is, a broken surface is a scored event. Worse, collocation errors cluster: a writer who does not think in partnerships makes several per paragraph, and the accumulation pushes the language band down a level.

The high-value collocation families

You cannot memorize every English collocation, and you do not need to. A small number of families cover most of the business writing the test elicits.

Delexical verb + noun. The verbs make, do, take, have, and give each own a fixed set of nouns, and swapping them is the most common error:

• make — a decision, a mistake, an effort, progress, an arrangement, a suggestion, a profit, an appointment
• do — business, research, homework, a favor, the paperwork, damage, your best
• take — a break, a risk, responsibility, action, a message, notes, place (an event takes place)
• have — a meeting, a discussion, an impact, access, a look
• give — a presentation, a discount, notice, permission, feedback, priority

"Let's do a meeting" and "we need to make research" are the signature errors; the correct partners are have a meeting and do research.

Adjective + noun. English fixes the intensifier:

• heavy rain, traffic, workload; strong wind, coffee, argument; high demand, priority, standard; deep concern, discount; wide range; close attention; key factor.

Strong rain, big traffic, and deep discount (the last is actually fine) show how narrow the tolerance is.

Verb + adverb and verb + preposition. Strongly recommend, fully understand, highly appreciate; comply with, depend on, result in, consist of, account for. The preposition is part of the word, not an optional add-on, and the wrong one — comply to, depend of — is a discrete, high-frequency error.

Business fixed phrases. Meet a deadline, reach an agreement, raise a concern, address an issue, place an order, submit a request, attach a file. These are near-idioms; the verb is not negotiable.

The four collocation failure modes

Failure 1 — First-language transfer

The writer translates the collocation from their first language word by word. If their language says the equivalent of do a decision or say an opinion, they carry the partnership into English. The fix is to stop translating pairings and to store the English pair whole — learn make a decision as one four-word chunk, not as make plus a decision.

Failure 2 — Reasoning from meaning

The writer chooses the partner by logic: rain is intense, strong means intense, therefore strong rain. But collocation is habit, not logic, and the logical choice is often the wrong one. The fix is to distrust the logical pairing for the high-frequency families and check it against the fixed partner.

Failure 3 — Wrong preposition after a verb

Depend on becomes depend of, comply with becomes comply to, result in becomes result to. Because the preposition carries little meaning, the writer treats it as free and picks whichever feels natural in their first language. The fix is to learn the verb and its preposition as a single unit — depend-on, comply-with — and never store the verb alone.

Failure 4 — Over-formal or archaic pairing

Reaching for impressive words, the writer produces pairings that are grammatically fine but stilted or dated — render assistance where provide help is wanted, commence the meeting where start is natural. The rubric rewards natural, appropriate register, not maximal formality. The fix is to prefer the common business collocation over the ornate one.

The drill — build partnerships, not words

Collocation improves when you change how you record and rehearse vocabulary, not when you study more of it.

Record words in their partners. When you meet a new noun, log it with its verb and adjective: not decision but make a decision, a difficult decision, reach a decision. Your vocabulary notebook becomes a phrasebook of partnerships, and you retrieve the chunk whole under test pressure.

Drill the five delexical verbs first. Take make, do, take, have, give and, one verb a day, write ten of its fixed noun partners in real business sentences. These five verbs generate the highest error density, so fixing them clears the most points fastest.

Use a substitution test. Before submitting, scan your intensifiers and delexical verbs and ask of each: is this the fixed partner, or the one I reasoned to? If you reasoned to it, check it. Most collocation errors are caught by this single pass.

Read to absorb, not to translate. Fluent collocation is built by exposure. Read business English — reports, emails, articles — and notice the pairings rather than the topics; the partnerships seep in when you stop translating and start noticing which words recur together.

How this shows up on the rubric

The vocabulary and language-use bands are not counting how many words you know; they are measuring whether your language reads as English. A writer with a modest vocabulary and flawless collocations reads as more fluent than a writer with a large vocabulary and broken partnerships, because the reader's sense of fluency is built on the surface — and collocation is the surface. Fixing the five delexical verb families and the fixed intensifiers repairs the most visible non-native signal in business writing, and it does so with words you already command.

The one-line takeaway

English stores which words partner which, and it does not compute them from meaning; learn vocabulary in its partnerships — make a decision, heavy rain, comply with — not as single words, and your writing reads native without your learning anything new.
