This is the adverb of 'uninhibited': it describes HOW someone does something — freely, openly, without holding back and without worrying about how they look. 'She laughed uninhibitedly.' 'He talked uninhibitedly about his childhood.' It sits most comfortably with verbs of feeling and expression: laugh, cry, dance, sing, talk, weep. It is a long word, five syllables (un-in-HIB-it-ed-ly), and English speakers feel that length — you meet it much more in books, reviews, and articles than in ordinary conversation. In everyday speech people usually say 'freely', or 'without holding back', or simply 'really': she really laughed. So it is a good word to recognise when you read, and a word to use sparingly when you write, saving it for a moment where the extra weight is doing something. Like its parent word, it can lean towards the sexual when it describes a person's behaviour in general rather than one particular action.
