有口无心
yoǔ koǔ wú xīn · HSK 7
to speak harshly but without any bad intent (idiom)
👄💭 有 have + 口 mouth + 无 no + 心 heart = sharp words, no real malice behind them
Literally have-mouth-no-heart: the mouth runs ahead of the heart. 无 (wú) negates 心 (xīn, heart/intent), so the blunt talk carries no ill will underneath.
有 — hand 𠂇 + moon/meat 月
Originally depicted a hand holding a piece of meat (月 here is the 'meat' radical, not moon), expressing the idea of possessing something. Over time the meaning broadened from 'to hold/possess' to the general sense of 'to have' or 'there is/exists'.
口 — pictograph of an open mouth
口 is one of the oldest pictographs in Chinese, originally drawn as a simple outline of an open mouth. Its core meaning 'mouth' extended naturally to 'opening' or 'entrance', as in 入口 (entrance). It also serves as a common radical in characters related to speech, eating, or apertures.
无 — top 一 + 林-like middle + fire radical 灬 below
Originally a pictograph of a person dancing while holding ornaments or tassels, meaning 'to dance' — the ancestor of 舞. It was borrowed phonetically to write the negative 'not have / without,' and the dance meaning was reassigned to 舞 with an added foot element. The simplified form 无 comes from an ancient variant.
心 — pictograph of a heart with chambers and aorta
心 is a pictograph showing a stylized heart, with strokes representing the organ's chambers and the aorta at the top. Originally meaning the physical heart, it broadened to cover mind, feelings, and intentions, since ancient Chinese thought located thinking and emotion in the heart.
