profundamente
/pɾoˌfundaˈmente/ · B1 · adv
profoundly, deeply
🌊 profunda (deep, like profound) + -mente (Spanish -ly) = profoundly
From Latin profundus: pro (forward) + fundus (bottom), so it means reaching to the bottom. English profound comes from the same root. Adding -mente turns a Spanish adjective into an adverb, the way -ly does in English.
