Adopter → It is formed from "ad-" (meaning to) and "optare" (meaning to choose). The word "adopter" refers to someone who chooses to take on or accept something, such as a child or a pet, as their own.
Think of someone 'choosing' ('optare') to take something 'to' them ('ad-') — that's why an adopter is someone who chooses to take in or accept.
