suficientemente
/sufiˌθjenteˈmente/ · A2 · adv
sufficiently
suficiente (sufficient) + -mente (-ly) = sufficiently
Spanish builds adverbs by adding -mente to an adjective, just as English adds -ly. Suficiente is a near-twin of English sufficient, both from Latin sufficere, to be enough. So the word reads as sufficient-ly.
