咯 (gē) is a phonetic character primarily used in onomatopoeic compound words like 咯噔 (gēdēng, 'thump') and 咯吱 (gēzhī, 'creak'). It does not carry meaning on its own; its function is to contribute to the sound symbolism of the disyllabic word. In writing, it almost always appears as part of a two-character onomatopoeic expression.
