Appearance
SCRUPLE, a term used in the two senses of (1) perplexity,
doubt, reluctance or hesitation, especially the moral doubt
arising from the difficulties of conscience; (2) a unit of weight,
124; part of the ounce in apothecaries' weight, ⅓ of a dram, 20
grains (1.295 grammes). The word is an adaptation of Fr.
scrupule, Lat. scrupulus, scrupulum, primarily a small sharp
stone, also used in both the English meanings, dim. of scrupus,
a rough stone, figuratively uneasiness of mind, probably to
be connected with the root skar, to cut, cf. Gr. σκῦρον,
stone-chippings, ζξυρόν, a razor.
