useful
🛠️ 有用 = 有 (have) + 用 (use) → having a use = useful
有 means to have, 用 means to use or function. Together they literally mean 'have-use' — something that has a use, i.e. useful. The English gloss 'profit/count' extends the same idea: it counts for something, it pays off.
有 — hand 𠂇 + moon/meat 月
Originally depicted a hand holding a piece of meat (月 here is the 'meat' radical, not moon), expressing the idea of possessing something. Over time the meaning broadened from 'to hold/possess' to the general sense of 'to have' or 'there is/exists'.
用 — pictograph of a bucket or wooden pail
用 originally depicted a bucket or container, possibly a sacrificial vessel made of wood. Over time it was borrowed to mean 'to use' or 'employ,' losing its concrete object sense. The modern meaning 'use' has been standard since early classical Chinese.
