蚊子
wénzi · HSK 7
mosquito
🦟 蚊 = insect radical 虫 + 文 (wén), where 文 just lends the sound; 子 is a noun-suffix
蚊 pairs the bug radical 虫 with 文 wén, a pure phonetic that fixes the reading. The 子 zi suffix turns it into an everyday noun, so 蚊子 wénzi literally reads as the buzzing bug, a mosquito.
子 — pictograph of a baby/child with arms out
子 began as a pictograph of a swaddled infant with a large head and outstretched arms, originally meaning 'baby' or 'child.' From there it broadened to 'son,' 'offspring,' and a respectful suffix for masters like 孔子 (Confucius). It also became one of the twelve earthly branches.
