🩹 贴 stick/paste + 切 close/cut = pasted-on close, so it fits snugly
贴切 describes a word or fit that sits right against the thing it covers. 贴 means to paste or stick on; 切 means close or pressed-tight. Together: as apt and snug as a sticker pressed flat with no gaps.
贴 — shell radical 贝 + occupy 占
A semantic-phonetic compound. The shell radical 贝 (originally cowrie shells used as money) signals the meaning, since 贴 first meant 'to pawn' or 'to pledge' something for money. The phonetic 占 (zhān) hints at the sound. The meaning later broadened to 'paste/stick on' and 'subsidy'.
切 — 七 (phonetic) + 刀 (knife radical)
切 is a semantic-phonetic compound: 刀 'knife' gives the meaning of cutting, while 七 supplies the sound. The original sense was to slice or cut with a blade. From there it extended figuratively to 'close to' (as in pressed against) and 'urgent/earnest', as in 切实.
