fuertemente
/ˌfweɾteˈmente/ · B2 · adv
strongly, hard, severely, heavily
💪 fuerte + mente = strong + in a manner: strongly
Fuertemente is fuerte (strong) plus the adverb ending -mente, like English -ly. Fuerte comes from Latin fortis, the root of fort and fortify. So it literally means in a strong manner.
