Etymology 1

From Middle English, from Old French contract, from Latin contractus (noun), from contrahere (“to bring together, to bring about, to conclude a bargain”) [from con- (“with, together”) + trahere (“to draw, to pull”)] + -tus (suffix forming nouns from verbs).

Etymology 2

From Middle English, from Middle French contracter, from Latin contractum, past participle of contrahere (“to bring together, to bring about, to conclude a bargain”), from con- (“with, together”) + trahere (“to draw, to pull”). The verb developed after the noun, and originally meant only "draw together"; the sense "make a contract with" developed later.
