IPA: /ˈhɪndˌwɪŋ/
KK: /hɪndwɪŋ/
A part of an insect's body, specifically the wing located at the back, which is used for flying and is often different in shape or size from the front wing.
The butterfly spread its hindwings to show off its beautiful colors.
Hindwing → It is formed from "hind" (from Old English "hind", meaning back or rear) and "wing" (from Old English "wenge", meaning wing or fin). The word "hindwing" refers to the wing located at the back of an insect or bird.
Think of the 'back' ('hind') wing of an insect — that's why it's called a hindwing.
