    Note

    The root meaning shows through here: Old English settan was the causative of the verb meaning "to sit," so to set a thing is, at bottom, to make it sit. That is why set and set down suit objects brought to rest in a place, and why the natural opposite is pick up. The same physical act, repeated with plates and cutlery, gives laying a table.

The other adds an -ing form, as when Coleridge remarked of Hamlet in 1827 that every incident sets him thinking. Both patterns are still alive in everyday speech, as in set the wheels in motion.

    A set may contain other sets.

    Note

    In mathematics the word carries strict rules that everyday collections do not. Membership is all that matters, so {1, 2} and {2, 1, 1} are the same set, because order and repetition are ignored. A set may have no members at all or infinitely many. Two sets are equal exactly when they contain the same members.

Meanings 1, 9, 14–15, 18–19, 21, 30

Old English had set ("seat, habitation, camp") and seten ("a shoot, slip, plantation, that which is planted"), both connected with settan ("to set"), and these gave Middle English set. For the senses meaning a group of people or things, some scholars take the word instead as a variant of sect, coming from Latin secta ("a faction") by way of Medieval Latin secta ("retinue") and Old French sette ("a religious sect"). The modern word may well be a blend of the two sources.
