🪝 钩 = 钅(metal) + 句 (gou phonetic) — a metal hook
The 钅radical on the left marks metal tools; the 句 component on the right carries the goū sound. Together: a metal thing pronounced goū — a hook. Same character covers the verb (to hook, to crochet) and the object.
钩 — metal radical 钅 + 句 (phonetic)
钩 is a semantic-phonetic compound. The metal radical 钅 (from 金) signals the meaning — a metal implement — while 句 gives the sound. It originally referred to a hook or curved metal tool, and the meaning extended to anything hook-shaped or the action of hooking.
