sort (n.)

late 14c., "group of people, animals, etc.; kind or variety of person or animal," from Old French sorte "class, kind," from Latin sortem (nominative sors) "lot; fate, destiny; share, portion; rank, category; sex, class, oracular response, prophecy," from PIE root *ser- (2) "to line up."

The sense evolution in Vulgar Latin is from "what is allotted to one by fate," to "fortune, condition," to "rank, class, order." Later (mid-15c.) "group, class, or category of items; kind or variety of thing; pattern, design." Out of sorts "not in usual good condition" is attested from 1620s, with literal sense of "out of stock."

mid-14c., "to arrange according to type or quality," from Old French sortir "allot, sort, assort," from Latin sortiri "draw lots, divide, choose," from sors (see sort (n.)). In some senses, the verb is a shortened form of assort.
