Pretty is a pretty common word in English, because it has an adjective, adverb, and verb form. You will most often hear it being used in its adverb form, where it means “moderately,” or “quite.” Note that it is different from very or so, which are used to emphasize or intensify the word that follows. For example, you would say: “I am very tired” or “I am so tired” when you are exhausted, and “I am pretty tired” when quite tired but not super tired.
