scrupulous

Etymology

It is inherited from Middle English scrupulous, also scrupulose,^[2] borrowed from Old French scrupulos, with the Anglo-Norman form scrupulus, and directly borrowed from Latin scrūpulōsus (“careful, exact”).^[2][3] Later dictionaries differ on the French step: Klein, the OED and the Shorter Oxford name French scrupuleux, the OED and the Shorter Oxford offering it beside Latin,^[4][5][6] while Merriam-Webster Unabridged and Dictionary.com name only Latin.^[7][8] The Latin adjective is from scrūpulus (“small sharp stone; uneasiness, pricking of conscience”), the source of scruple,^[9] and a diminutive of scrūpus (“sharp stone, pebble”).^[10][3][4] Etymonline calls the origin of the Latin noun unknown,^[3] while Barnhart refers it to Proto-Indo-European *skreup- and Klein, as a probable derivation, to Proto-Indo-European *sqreu-p- (“to cut or break to pieces”).^[10][4]

Earliest recorded meaning

Marked by fine distinctions of doubt: in Pecock's Rule of about 1443, oure scripulose resoun.^[2] Barnhart also dates the word to about 1443, with the sense of being very careful to do what is right.^[10] The first quotation in the OED, whose entry is not fully revised, is from 1528, in Henry VIII, for being troubled by doubts of conscience.^[5]

Semantic evolution

The Latin adjective had both a concrete sense, "full of sharp rocks, jagged", and a figurative one, "careful, taking precautions"; the Book of Word Histories pictures someone facing a rocky situation.^[9] English took only the figurative side.^[9] In the 16th and 17th centuries the emphasis was on doubt: the word described people troubled in conscience, or prone to hesitate (1559–1695), and things that raised doubts (1548–1685).^[5] From 1542 it could also mean careful to follow one's conscience,^[5][3] which is the main moral sense today.^[7] From there it spread to non-moral matters, as "minutely exact", in 1638.^[5][3] Johnson (1755) still listed "nicely doubtful" first, followed by "given to objections; captious" and only then "careful; vigilant; cautious".^[11] In Scots it could mean "doubtful, inquisitive": Galt used it this way in Ayrshire in 1826.^[12]
