favoriteadjective
British spelling: favourite

Word family
Usage
Favorite already means best liked, so more favorite and most favorite are not standard. My most favorite is heard in informal speech but avoided in careful writing, where my favorite is enough; my absolute favorite and my all-time favorite are common ways to add emphasis instead. Standing on its own (Which is your favorite?), it is a noun with its own entry: favorite (noun). In British spelling the word is favourite, and so is the noun.

For translators
Meaning across languages Many languages say the one I like most with a superlative; English uses this ordinary adjective before the noun, almost always with a possessive: my favorite, her favorite.
