How to Write 咔 (kā) — Meaning “click; crack (onomatopoeia)”

Imagine a mouth (口) saying "ka" like the sound of a camera shutter clicking. Picture the right part 卡 as a card being snapped in half, making a crisp "kā" noise. This mental image links the shape to the meaning of a click or crack.

Write the left radical 口 small and slightly above center, using three strokes (vertical, horizontal bottom, then top horizontal? Actually standard order: left vertical, top horizontal, right vertical, then bottom horizontal? For 口, order is vertical, horizontal, horizontal, vertical? Wait, standard: 口 is 竖,横折,横. But for the whole character, first write 口 (3 strokes), then 卡 (5 strokes). The right part 卡 starts with a vertical line, then a horizontal, then a vertical line crossing, then a horizontal, then a dot at the bottom. A common mistake is making the 口 too large or misaligning the vertical strokes of 卡.

吁 (xū) has the phonetic component 于 and means a sigh or exclamation, while 咔 uses 卡 for clicking sounds. 吂 (máng or similar) is a rare character with a different sound and meaning. Visually, 咔 has the distinct 卡 (a "up-down" shape) on the right, while 吁 has 于 (a cross with a hook) and 吂 has a more rounded component.

咔 appears mainly in onomatopoeic words like 咔嚓 (kāchā, snapping sound) and 咔哒 (kādá, clicking sound), often used in comics, descriptions of mechanical noises, or photography (shutter click). It is not part of the HSK system, so it's mostly encountered in casual or creative writing rather than formal texts.

Common words containing 咔 include: 咔嚓 (kā chā) — click; snap (onomatopoeia); 咔哒 (kā dá) — click-clack (onomatopoeia); 咔叽 (kā jī) — khaki (fabric).
