Adjectives spelled with a written accent (such as , , ) keep the written accent when they are made into adverbs with the "-mente" ending (thus , , ), and do not gain any if they do not have one (thus from ). In the pronunciation of these adverbs—as with all adverbs in —primary stress is on the ending, on the penultimate syllable. The original stress of the adjective—whether marked, as in "fácilmente", or not marked, as in "libremente"—may be manifested as a secondary stress in the adverb.
