IPA: /ˈʌndərˌʃɜrt/
KK: /ˈʌndərˌʃɜrt/
A type of clothing worn under a shirt, usually without sleeves, that covers the upper body.
He wore an undershirt to stay comfortable under his dress shirt.
Undershirt → It is formed from "under-" (meaning beneath or below) and "shirt" (from Old English "scyrte", meaning a garment worn on the upper body). The word "undershirt" refers to a shirt worn beneath another garment, typically for added warmth or comfort.
Think of wearing a shirt that goes 'beneath' ('under-') your outer clothing — that's what an undershirt is.
