TOEIC Link Part 5: adapt versus adopt versus adept

Adapt, adopt, and adept look and sound almost alike — one or two letters apart — but they share no meaning, and Part 5 uses that closeness to set traps. Adapt is a verb meaning to adjust to new conditions. Adopt is a verb meaning to take up or formally approve something. Adept is an adjective meaning highly skilled. Because business passages constantly mention adjusting to change, approving policies, and skilled staff, the test can put any of the three in play. For another set of look-alike words separated only by meaning, see accept versus except, and for a confusable verb pair, see comprise versus compose versus consist.

The core rule: adjust versus take-up versus skilled

• adapt (verb) = to adjust or modify to fit new conditions: The company adapted its strategy to the new market.
• adopt (verb) = to take up, choose, or formally approve: The board adopted the new safety policy.
• adept (adjective) = highly skilled, expert: She is adept at negotiating contracts.

A memory hook: adapt has the same a as adjust. Adopt has the same o as officially okay (approve). Adept has the same e as expert.

How to read the slot

Part of speech splits adept from the other two; meaning then splits adapt from adopt.

• adept is the only adjective of the three. It follows a linking verb or comes before a noun, and it pairs with at or in: adept at coding, an adept manager. If the slot needs a word meaning skilled, choose adept.
• adapt is a verb about changing to fit. It often takes to or a reflexive object: adapt to the climate, adapt the design. If the slot means adjust, choose adapt.
• adopt is a verb about taking something up. Its object is usually a policy, plan, method, technology, or measure: adopt a framework, adopt new software. If the slot means approve or take up, choose adopt.

So the fastest test: skilled (adept), adjust to fit (adapt), or take up / approve (adopt)?

Common Part 5 traps

• "(blank) at / in something" is adept. The preposition at or in plus a skill signals the adjective: engineers adept at troubleshooting.
• "(blank) to new conditions" is adapt. The preposition to plus a changing situation signals adjust: staff must adapt to remote work.
• "(blank) a policy / plan / technology" is adopt. A formal object being taken up signals approve: the firm adopted cloud computing.
• Watch the single-letter swap. adapt (adjust) and adopt (take up) differ by one vowel and are the most frequently confused pair; do not let "adopt to change" slip in — adjusting is always adapt.

Why this pair matters on TOEIC

Business English leans on all three constantly: organizations adapt to markets and regulations, adopt policies, tools, and standards, and rely on staff who are adept at their work. Because the words differ by only a letter or two, you can never rely on sound or shape; lock onto meaning and part of speech instead. at/in plus a skill means the adjective adept; to plus a changing condition means adapt; a policy or method as object means adopt. For another trio where small differences carry big meaning, compare assure versus ensure versus insure.
