Feeling uneasy, anxious, or disturbed; made restless or troubled.
From disquiet (verb) + -ed (past participle/adjective marker). When used as an adjective, it means 'put into a state of disquiet.'
Adding -ed to create adjectives is brilliantly efficient—'disquieted' instantly conveys someone's emotional state, painted with the specific color of being troubled rather than happy or sad.
