bridesmaid

The word 'bridesmaid' is a transparent compound from Old English elements, literally meaning "the bride's young female attendant." The 's' is a fossilized genitive (possessive) case marker, common in older English compounds, linking the bride to her attendant. The term 'maid' originally specified a young, unmarried woman, reflecting the historical custom of the bride's companions being unwed. Over time, the term has generalized to refer to any woman, married or not, who serves as an official attendant to the bride, while the core logic of the bride's supportive companion remains intact.
