Etymology: The noun "adaptations" is simply the plural of "adaptation," and the story of the singular runs back to a Latin verb meaning to fit something to something else. Latin "adaptō" combined "ad-" ("to") with "aptō," a verb built from "aptus," meaning "fitted" or "suitable," so the core sense was physical fitting: making one thing match another. Medieval Latin turned the verb into the noun "adaptātiō," and French took it up as "adaptation." English borrowed the word from French, and it carried that original sense of adjusting something so it suits a new purpose, such as reworking a play for the stage or a novel for the screen. The biological sense of an inherited trait that helps an organism survive in its environment came later, and it is this meaning the phrase "changes for survival" points to.
