IPA: /ˈmaʊθpɑrt/
KK: /maʊθpɑrt/
A part of the mouth of an insect or other arthropod that is adapted for feeding or gathering food.
The butterfly uses its mouthparts to sip nectar from flowers.
Mouthpart → It is formed from "mouth" (from Old English *muð*, meaning the opening through which food is taken) and "part" (from Latin *partem*, meaning a piece or division). The word "mouthpart" refers to a part or component of the mouth.
Think of the 'opening' ('mouth') where food enters and a 'piece' ('part') of that opening — that's why 'mouthpart' refers to a component of the mouth.
