Adverbs from Adjectives
Most Spanish adverbs that describe 'how' an action is performed are created by taking the feminine form of an adjective (e.g., perfecta) and adding the suffix '-mente' (meaning 'in a manner').
Using the Adjective instead of the Adverb
Mistake: “Hablo español perfecto.”
Correction: Hablo español perfectamente. (You must use the '-mente' ending when describing the verb 'hablar' (to speak).)
