加强
jiāqiáng · HSK 3
strengthen
💪 加 (add) + 强 (strong) = add strength → strengthen, reinforce
加 means add/increase; 强 means strong/powerful. Together they literally mean 'add strength,' giving the sense of strengthening, augmenting, or reinforcing something.
加 — force 力 + mouth 口
加 is traditionally analyzed as a compound of 力 (strength) and 口 (mouth), suggesting boasting or exaggerating one's effort with words. From this it extended to the meaning 'to add' or 'increase'. Today it is used broadly for addition, both literal and figurative.
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.
