What does mercer mean?
A mercer was a merchant who dealt in textiles, particularly cloth, before the clothing industry became dominated by large manufacturers and retailers. The word survives as an occupational surname associated with families whose ancestors traded in fabrics, and it also gives us the verb mercer, meaning to treat cotton with an alkaline solution. This process, also called mercerization, increases the fabric's smoothness, strength, lustre, and ability to absorb dye evenly. The term is consequently preserved not only in family names but also in technical vocabulary used by textile manufacturers. Although the traditional occupation it names has largely passed from ordinary use, mercer remains significant in genealogy, industrial history, and the study of textile processing.

Where does mercer come from?
Mercer entered Middle English from Anglo-French mercier, a merchant or dealer, from Latin mercarius, itself associated with mercari, “to trade,” and ultimately with merx, “wares” or “merchandise.” Cognates include merchant, mercantile, commerce, and mercenary, all of which reflect the same broad ancient trading and payment vocabulary. The later verb came through French merceriser and originally referred to the preparation of cotton for dyeing.
