Etymology

The word "undershirt" is a transparent compound formed from two Old English elements. The first element, "under," originates from Proto-Germanic under, which itself descends from the Proto-Indo-European root ndher-, meaning "under." The second element, "shirt," comes from Old English scyrte, meaning a short garment or tunic, related to the Proto-Germanic skurtijǭ and ultimately to the pie root (s)ker-, "to cut." The compound's logic is entirely literal: a shirt worn under another garment. It emerged in the late 16th century, reflecting the practical need to name a specific layer of clothing in the evolving English wardrobe, directly linking the garment's function to its descriptive name.
