‘Adopt’ vs ‘Adapt’: What’s the difference? When the only thing that separates two words is one little letter, we have to take extra care to learn their differences. Learn how to ‘Adapt’ to small changes and ‘Adopt’ a better understanding of new vocabulary with this article. 

Are you in a rush? Here’s a quick preview of what you’ll learn:

  • ‘Adopt’ is a word that means to choose or to take on legally
  • ‘Adapt’ is a word that means to modify something to make it suitable

What’s the Difference Between ‘Adopt’ vs ‘Adapt’?

The obvious difference between these two words is their one-letter change, but what does that tell us about these words? Let’s first look at their origins. 

Both ‘adopt’ vs ‘adapt’ use the Latin prefix ‘ad-’ which means “to.” Since those are the same, we can look at their roots/suffixes to identify a difference.

  • The root of ‘adopt’ is the Latin ‘optare’ which means “choose,” kind of like the word “option.” You can use the root to remind you that ‘adopt’ means to choose or have options. 
  • Meanwhile, the root of ‘adapt’ is ‘aptare’ which comes from ‘aptus’ meaning “fit.” When something ‘adapts’ it fits into a new place or circumstance, so use the root as a reminder of that.

Of course, if one is easier to recall than the other, you can memorize one and then use the process of elimination. But this way, you have an understanding of where each word came from. Similarly to using the roots as reminders, you can also use other spelling hints. 

The word ‘adapt’ starts similarly to its synonym ‘adjust.’ You can use the first two letters “ad-” as a context clue in that case.

  • Be careful not to combine that with the first two letters of ‘adopt.’

Meanwhile, remember that ‘adopt’ has an ‘o’ in it, just like the word “choose,” which you can use as a hint to its meaning. 

Yet, while all of this is helpful, it doesn’t give us a full picture of the individual meanings of each word. Let’s look closer and dive into the definitions of ‘adopt’ vs ‘adapt.’
