From Middle English sett, from Old English ġesett, past participle of settan.

From Middle English set, sete, sette (“that which is set, the act of setting, seat”), from Old English set (“setting, seat, a place where people remain, habitation, camp, entrenchment, a place where animals are kept, stall, fold”) and Old English seten (“a set, shoot, slip, branch; a nursery, plantation; that which is planted or set; a cultivated place; planting, cultivation; a setting, putting; a stopping; occupied land”), related to Old English settan (“to set”). Compare Middle Low German gesette (“a set, suite”), Old English gesetl (“assembly”). According to Skeat, in senses denoting a group of things or persons, representing an alteration of sept, from Old French sette (“a religious sect”), from Medieval Latin secta (“retinue”), from Latin secta (“a faction”). See sect. It is quite possible that the modern word is more of a merger between both, however.
