TOEIC Link Part 5: business and finance confusable pairs study guide

The TOEIC Link measures English for the workplace, so its Part 5 vocabulary questions draw from the language of money, hiring, meetings, and office operations. That focus is predictable, and it means a specific set of confusable word pairs appears again and again — the ones that cluster around finance and business administration. If you learn this cluster, you cover a disproportionate share of the word-choice questions you will actually see.

This guide groups those pairs by the business situation where they appear, explains the clue that settles each blank, and links to a focused lesson for every pair. Unlike the general commonly confused word pairs master index, this page stays inside the finance-and-office domain so you can drill the vocabulary that matches TOEIC Link passages.

Money and capital

Finance vocabulary produces some of the trickiest homophones on the test, because a wrong answer often still sounds like it belongs in a business sentence.

• capital versus capitol — capital is money or assets for investment (also a leading city); capitol is only the building where a legislature meets. Business passages use capital constantly, which is exactly why the test can slip in the rarer word.
• principal versus principle — in finance, principal is the original sum of a loan or investment before interest; principle is a rule or belief. "Repay the principal" is money; "a matter of principle" is ethics.
• depreciate versus deprecate — assets depreciate (fall in value over time); people deprecate (express disapproval). Balance-sheet sentences want depreciate.
• disburse versus disperse — a finance department disburses funds (pays them out); a crowd disperses (scatters). Money is paid out, not scattered.

Clue: if the sentence is about a sum of money, look for the word tied to sums — capital, principal, depreciate, disburse — not its look-alike.

Hiring, staff, and personnel

Human-resources sentences carry their own reliable traps.

• personnel versus personal — personnel are the staff of an organization (a plural collective); personal means private or individual. "The personnel department" versus "personal belongings."
• council versus counsel — a council is a governing body that meets; counsel is advice, or a lawyer. HR and legal passages use both, so read for whether the sentence names a group or an act of advising.
• appraise versus apprise — a manager appraises performance (evaluates it) and apprises staff of a decision (informs them). Reviews appraise; announcements apprise.

Clue: decide whether the blank names people, a body of people, or an action taken toward people, then match the form.

Growth, spending, and operations

Operational vocabulary tests verbs of expansion and outlay that share sounds or roots.

• expand versus expend — a company expands (grows larger) and expends resources (spends them). Growth versus expenditure.
• economic versus economical — economic relates to the economy or finances broadly; economical means money-saving or efficient. "Economic conditions" versus "an economical option."
• comprise, compose, and consist — used constantly to describe how a division, portfolio, or board is structured. The whole comprises the parts; the parts compose the whole; the whole consists of the parts.

Clue: separate the idea of getting bigger from paying out, and the whole from the parts, before you choose.

Office and correspondence

Even the vocabulary of paperwork and outreach hides confusable pairs.

• stationary versus stationery — stationary means not moving; stationery is paper, envelopes, and office supplies. An order for the office wants stationery.
• canvas versus canvass — canvas is heavy cloth; to canvass is to survey opinions or solicit business. A marketing sentence about gathering feedback wants canvass.
• complement versus compliment — a product line that complements another completes it; a compliment is praise. Business writing about fit and coverage wants complement.

Clue: ask what the object is — a physical thing, an act of outreach, or an act of praise — and let the object choose the word.

A one-week drill plan

1. Day 1–2: money and capital pairs. These carry the highest weight because finance vocabulary dominates TOEIC Link reading.
2. Day 3–4: personnel and hiring pairs.
3. Day 5: growth, spending, and operations.
4. Day 6: office and correspondence.
5. Day 7: mixed re-test. Pull one blank from each pair and answer without the lesson open.

Because these pairs recur across almost every business passage, mastering the finance-and-office cluster gives you a faster return than working through vocabulary at random. When you are comfortable here, widen out to the full commonly confused word pairs master index, and review how word-choice questions fit the section in what is TOEIC Link.
