irrespective

Etymology

It is formed from English ir- + respective,^[2][3][4][5] ir- being the form of the negative prefix in- before r,^[6][5] and respective here in its old sense of "regardful".^[6] Respective is from Medieval Latin respectīvus (“having regard for”), from respiciō (“to look back at, regard”).^[6]

Earliest recorded meaning

Not respectful, disrespectful: 1640, in R. Baillie.^[2][3] Etymonline finds the sense implied in the 1620s, in irrespectively,^[6] and Dictionary.com dates the word 1630–40.^[7]

Semantic evolution

The first sense, "disrespectful", died out by the 1650s.^[2][3] From 1650 the word described acting without regard to particular persons, circumstances or conditions,^[2] a use Etymonline explains from the idea of "not observing or noting with attention";^[6] it was common in 17th-century theology, as when Johnson (1755) quoted Hammond on a believer's "particular irrespective election".^[8] The OED and the Shorter Oxford call this sense now rare,^[2][3] and Merriam-Webster labels it archaic.^[4] The sense "without regard to, independent of" appears in 1689,^[2] and in modern use the word is mostly adverbial, in irrespective of,^[6][2] which Etymonline dates to about 1800 and the OED's adverbial sense to 1839.^[6][2]
