Your beloved is someone you love. You can also talk about a beloved pet or possession.
You probably have some things you really love: a bike, a skateboard, a book, a DVD, maybe a souvenir from a trip. Those are beloved possessions — you really like them a lot. People also talk about beloved family members, beloved pets, and beloved friends. This is a word for things and people you're crazy about. And if you're feeling really crazy on Valentine's Day, go ahead and tell your crush that she's your beloved.
