Acquired is not something you're born with: you gain or develop it later in life, like your acquired taste for coffee.
Acquired comes from the Latin word acquirere, meaning "to seek in addition to." You may the verb acquire, meaning "to get or obtain," as in your habit of acquiring pairs of sneakers. So, something acquired is something you have gotten, not something you always had. For example, if you have an acquired habit of reading novels, this is something that developed over time. After all, you weren't born reading!
