When someone looks guilty, they might wear a furtive expression on their face, look sheepish or shifty-eyed, or appear sneaky and evasive. Other synonyms for looking guilty include seeming apprehensive, uneasy, nervous, suspicious, and jittery. A guilty expression can also manifest as appearing tense, hesitant, self-conscious, or on edge. Nonverbal cues such as avoiding eye contact, hunching over, or sweating profusely could all suggest a guilty conscience. Similarly, a person might appear regretful, remorseful, shamefaced, or contrite when they look guilty. Detecting these signs can be crucial in identifying if someone is hiding something or feels guilty about something they have done.
