Other forms: afterthoughts
An afterthought is something you think of or add later. You might quickly wrap a gift and then stick a bow on it as an afterthought just before you hand it to the birthday boy.
Sometimes calling something an afterthought is a bit of an insult — a movie reviewer might complain that female characters seem added on as afterthoughts, or a diner at a fancy restaurant could note that while the meat is well-cooked, the vegetables are nothing but an afterthought. This word has been used since the 1600s, a compound of after and thought.
