-ess

suffix

Etymology: From Middle English -eis, a borrowing from Old French -eis, a locative suffix descended from Latin -ensis. The French and Middle English suffixes created nouns describing a freeman of a fortified town, but in Modern English this is found only in proper nouns, particularly in certain surnames. Cognates include Italian -ese, and English English -ese is a doublet.
