Emanate means to give off, like the sound of laughter that emanates from your sister's room during her slumber party. If spooky sounds emanate from the closet, don’t open the door!
The word emanate comes from the Latin emanare, which means “to flow out.” Things that emanate come from somewhere. Heat emanates from a fire, and smoke emanates from a chimney. This word can also be used figuratively: for example, you might say that your upbeat and optimistic best friend emanates positivity.
