incorrectly written or mispronounced characters
✏️❌ wrong + separate + character = characters written or said incorrectly
错 means wrong or mistaken, 别 means other or separate, 字 means character. Together they label characters that deviate from the correct form — either misspelled on paper or mispronounced aloud.
错 — metal radical 钅 + 昔 (xī, former times)
A semantic-phonetic compound: 钅(金) 'metal' gives the meaning, while 昔 supplies the sound. It originally referred to gilding or inlaying metal, then extended to 'interweave, alternate,' and from 'crossed/mixed up' came to mean 'wrong, mistaken.'
别 — separate (knife 刂 + 另 phonetic/'other')
别 originally depicted using a knife (刂) to separate flesh from bone, giving the core sense of 'divide' or 'part from'. The left component 另 ('another, other') reinforces the idea of setting things apart and also hints at the sound. From 'separate' the meaning naturally extended to 'other, different' and to the adverb 'don't' (i.e. do otherwise).
字 — roof 宀 + child 子
Originally depicted a child 子 under a roof 宀, suggesting birth or rearing a child in the home. The meaning later extended to 'to give birth, nurture' and then to 'written character', since characters were seen as offspring derived from earlier pictographs.
