常识
chángshì · HSK 4
general knowledge
💡 常 (常 cháng = often/usual) + 识 (shì = knowledge) = usual knowledge
常 means 'often' or 'common', and 识 means 'knowledge' or 'recognition'. Together: the knowledge everyone commonly has — common sense or general knowledge.
常 — 巾 (cloth) + 尚 (phonetic, 'esteem')
Originally written 裳, 常 was a phono-semantic compound: 巾 ('cloth') gave the meaning and 尚 supplied the sound, referring to a long lower garment or skirt. Over time the meaning shifted from 'everyday garment' to 'ordinary, regular, constant', while 裳 took over the original clothing sense.
识 — speech radical 讠 + 只 zhī (phonetic)
识 is a semantic-phonetic compound. The speech radical 讠 (言) signals meaning related to words or knowing, while 只 hints at the sound. Originally written 識 with 戠, it meant 'to recognize' or 'know'; later it broadened to include knowledge and awareness.
