TOEIC Link Part 5: adapt versus adopt
Adapt and adopt are separated by a single vowel, yet they describe two different actions. Adapt means to adjust or modify something so it fits a new situation or condition. Adopt means to take something on, accept it formally, or start using it as your own. Part 5 rewards you for asking whether the blank describes changing something to fit or taking something up. For the wider set of look-alike traps, start with the commonly confused word pairs master index.
The core rule: adjust to fit versus take on
- adapt (verb) = to adjust or modify to suit new conditions. The company had to adapt its packaging for overseas markets. It answers did they change it to fit? Anchor it with -apt = make it apt (suitable) — you reshape something so it works in a new setting.
- adopt (verb) = to take on, accept, or begin using as one's own. The board voted to adopt the new safety policy. It answers did they take it up formally? Anchor it with -opt = opt in — you choose to accept something and make it yours.
A quick anchor: adapt = adjust to fit; adopt = take on as your own. One reshapes to suit conditions, the other accepts and puts into use.
Why Part 5 likes this pair
The two words differ by only one letter and both appear in business contexts about change, so the wrong option passes a quick glance. The item is decided by which action the sentence supports: modifying something to suit new conditions points to adapt, while formally taking something up points to adopt.
Employees were asked to __ their workflow to the updated software.
The blank describes adjusting the workflow to fit the new tool, so it needs adapt.
The committee decided to __ the revised expense guidelines next quarter.
The blank describes formally taking up the new guidelines, so it needs adopt.
Spotting the clue
Check whether the blank describes adjusting something or taking something on:
- Is the word about changing or modifying to fit a situation? → choose adapt (adapt to change, adapt the design, adapt a recipe).
- Is the word about accepting, approving, or starting to use something? → choose adopt (adopt a policy, adopt new technology, adopt a strategy).
A quick test: can you replace the word with "adjust" or "modify"? Then it is adapt. Can you replace it with "take on" or "accept"? Then it is adopt. In TOEIC business scenarios, adapt tends to appear with adjusting products, plans, or behavior to new markets, tools, or circumstances — often followed by to — while adopt shows up with approving policies, standards, technologies, or methods and putting them into use. Watch the preposition: adapt to conditions signals adjustment, while adopt usually takes a direct object you accept.
