increíblemente
/inkɾeˌibleˈmente/ · B1 · adv
incredibly
🤯 increíble + -mente = incredible + -ly; in- (not) + creer (believe)
Increíble is from Latin incredibilis: in- (not) + credere (to believe), so something you can't believe. Adding -mente, from Latin mens (mind), turns an adjective into an adverb, just like English -ly.
