otiose

Etymology

It is borrowed from Latin ōtiōsus (“at leisure, unemployed, idle; ineffectual”),^[2][3][4][5] from ōtium (“leisure, ease”) and -ōsus.^[2][6][7] The origin of ōtium is uncertain or unknown.^[2][4][8][9] It is also the second part of negōtium (“business”), the source of negotiate.^[10][4] The Latin adjective gave French oiseux, Spanish ocioso and Italian ozioso.^[2][4] English had taken the same family of words earlier, in otiosity (1483, in Caxton) and otious (1614), and Barnhart therefore calls otiose a reborrowing.^[9][2]

Earliest recorded meaning

Having no practical result, futile, said of belief or principle: 1795, in W. Paley's View of Evidences of Christianity,^[2][7] which Barnhart and Etymonline date to 1794.^[9][4] Dictionary.com gives 1785–95.^[6]

Semantic evolution

The word began with "futile", and by 1837, in G. Phillips's Syriac Grammar, had come to mean "having no practical function, redundant",^[2] a sense that Barnhart dates to 1866.^[9] The sense closest to the Latin root, "at leisure, idle", is recorded only from 1850,^[2][4][9] the earlier word for it being otious, "at ease".^[4][2] Hoad labels that sense archaic and Collins rare,^[5][11] and the "superfluous" sense is the one Collins now gives first.^[11] Merriam-Webster Unabridged adds a use for a deity who is remote and not concerned with the details of the world.^[7]
