Origin and history of approximate

approximate(adj.)

1640s, "near in position, close to," from Late Latin approximatus, past participle of approximare "to come near to," from Latin ad "to" (see ad-) + proximare "come near," from proximus "nearest," superlative of prope "near" (see propinquity).

The meaning "near in accuracy or correctness" is by 1816. It also was used in Middle English in a sense of "similar" (early 15c.).

Entries linking to approximate

late 14c., propinquite, "nearness in relation, kinship," later also "nearness in place, physical nearness" (early 15c.), from Old French propinquite (13c.) and directly from Latin propinquitatem (nominative propinquitas) "nearness, vicinity; relationship, affinity," from propinquus "near, neighboring," from prope "near," with loss of second -r- by dissimilation, from PIE *propro "on and on, ever further" (source also of Sanskrit pra-pra "on and on," Greek pro-pro "before, on and on"), from root *per- (1) "forward," hence "in front of, toward, near." The signification of the suffix -inquus is unclear.
