felizmente
/ˌfeliθˈmente/ · B2 · adv
happily
😊 feliz + -mente = happy + manner suffix, so happily
Feliz means happy, and the suffix -mente (from Latin mente, 'in a mind/manner') turns adjectives into adverbs, like English -ly. So feliz-mente is literally 'in a happy manner'. The same suffix gives rápidamente, claramente.
