尴尬 (gān gà) is an adjective describing a strong feeling of social discomfort, self-consciousness, or embarrassment—often arising from an unexpected, inappropriate, or socially clumsy situation. Neither character alone carries this meaning: 尴 originally referred to uneven terrain or instability, and 尬 meant 'to lift the legs' or 'to stumble'; together, they evoke a sense of being off-balance, trapped, or unable to act smoothly in a social moment.

The word is commonly used to describe situations where someone says or does something awkward, makes a social blunder, or finds themselves in an uncomfortable interpersonal exchange—like mispronouncing someone’s name in front of them, walking into a room full of silent people, or realizing you’ve been talking to a stranger thinking they were your friend. It can also describe the atmosphere itself (e.g., an ‘awkward silence’), not just personal feelings.
