rápidamente
/ˌrapidaˈmente/ · B1 · adv
rapidly, quickly
🐇 rápida + mente = rapid + -ly: rapid-ly
Spanish builds adverbs by adding -mente to the feminine adjective, just as English adds -ly. Rápida (rapid) + mente gives rapidly. The ending comes from Latin mente, meaning with a mind, so it once meant with a rapid mind.
