Is It Adapt or Adopt? Difference, Examples, and Easy Rule

Adapt means to change something for a new use or situation. Adopt means to take up, accept, or legally take responsibility for something. If you are choosing between these words, start with the meaning of the sentence, not with the sound of the word.

The company will adapt the software for schools.
They plan to adopt a new policy next month.

These two words are easy to confuse because English often has similar-looking or similar-sounding words with different jobs. The safe rule is simple: use adapt when you mean to change something for a new use or situation; use adopt when you mean to take up, accept, or legally take responsibility for something.
