Morphology

coat + button

The meaning 'a button used for fastening a coat' is directly and compositionally derived from 'coat' (an outer garment) + 'button' (a fastener). This simple noun–noun compound follows a common, cross-linguistic naming pattern for object parts, so a B1 learner who knows both words will readily understand it.

Etymology

Coat button simply names a button on a coat; imagine a small round piece sewn to the front that you push through a hole to keep the coat closed. That's why it means 'a button used for fastening a coat'.
