- scrup (from Latin scrupulus, meaning "small sharp stone" or "anxiety," derived from scrupus "rough pebble")
- le (diminutive suffix in Latin, indicating smallness or triviality)
Etymology Origin:
The word scruple originated from the Latin scrupulus, a diminutive of scrupus ("sharp stone"). The metaphorical shift from "pebble in one’s shoe" to "mental unease" reflects how physical discomfort evolved into moral hesitation. By the 17th century, it also denoted a tiny weight unit, further emphasizing its association with smallness.
