同学
tóngxué · HSK 1
classmate
🎒 同 (same) + 学 (study) = people who study the same thing → classmate
同 means same/together; 学 means study or learn. A 同学 is literally a same-study person, i.e. someone you share lessons with. The compound is fully transparent once you know the two characters.
同 — 冂 enclosure + 一 + 口 mouth
Originally depicted multiple mouths gathered under one cover or enclosure, suggesting people speaking together in agreement. From this image of voices joining, it came to mean 'same,' 'together,' or 'alike.' The shared cover symbolizes unity.
学 — hands 𦥑 + roof 冖 + child 子
Originally 學, depicting two hands manipulating something (often interpreted as counting rods or the 爻 trigram symbols) under a roof, with a child 子 below — a child learning under instruction. The simplified form 学 replaces the top with a stylized 龸. Core meaning has always been 'to study, learn'.
