强度
qiángdù · HSK 5
strength
💪 强 (strong) + 度 (degree) = strength/intensity, the degree of force
强 means strong or powerful; 度 means degree or measure. Together they literally mean degree-of-strength, used for intensity of light, sound, effort, or any measurable force.
强 — bow 弓 + elong 㔾 + insect 虫
Originally written 強, depicting a type of strong-shelled insect or weevil, with 虫 (insect) as semantic and 弘 as phonetic. The meaning shifted from the insect's tough shell to the general sense of 'strong, powerful, forceful.' The form 强 is a common variant where 弘 is replaced by 弓+口.
度 — 广 (shelter) + 庶 abbreviated (phonetic)
Originally depicted a hand measuring length under a shelter, meaning 'to measure' or 'a measure/standard.' From this came extended senses like 'degree,' 'extent,' and 'to pass through' (as in passing time). The reading 'dù' means degree/measure, while 'duó' preserves the older verbal sense of measuring.
