reluctance

Etymology

The revised OED takes it as formed from English reluctant + -ance, comparing Italian reluttanza.^[2][3][4] Barnhart and Etymonline instead derive it from the obsolete verb reluct, to struggle against (1526), with -ance, and Barnhart allows that it may sometimes be a back-formation from reluctancy (1621).^[5][6] The adjective reluctant is from Latin reluctāns, the present participle of reluctor (“to struggle against, resist”),^[2][6][7] formed from re- (“back, against”) and luctor (“to struggle, wrestle”),^[6][2][8] which Etymonline derives from Proto-Italic *lukto- and Proto-Indo-European *lug-to- (“bent”),^[6] citing as cognates Ancient Greek λύγος (lúgos, “withy, pliant twig”) and Old English locc (“lock of hair”).^[6][5]

Earliest recorded meaning

Struggle or resistance against something: 1609, in a work of Bishop W. Barlow,^[2] 1609 also in Merriam-Webster;^[9] Barnhart and Etymonline date this sense to 1641 and the 1640s.^[5][6]

Semantic evolution

The word first meant a physical or moral struggle against something, a sense the OED records until 1884.^[2][3] Milton wrote of "the reluctance ... which is in all Kings against Presbyterian and Independent Discipline".^[3] The modern sense "unwillingness, disinclination" is recorded from before 1628 in the revised OED,^[2] from 1667 in Barnhart and the 1660s in Etymonline,^[5][6] and is now the usual one.^[2] Partridge notes that in Late Latin the verb also meant to force oneself to do something.^[8] Other 17th-century senses, recoiling from something and, apparently through association with Latin luctus (“grief”), regret or sorrow (1650–1710), died out.^[2] In 1888 Heaviside used reluctance for the opposition of a magnetic circuit to magnetic flux, by analogy with electrical resistance.^[2][10]
