Etymology

Origin of scrupulous

First recorded in 1400–50; a late Middle English word from Latin scrūpulōsus; see scruple, -ous

Explanation

Scrupulous means very careful to do things properly and correctly. If you're scrupulous, you probably pay your friends back right away when they loan you money and never try to return clothing you've already worn. A scrupulous person is full of scruples, which are concerns about doing things that are morally right. Such a person is hesitant or doubtful, and might have trouble deciding what is morally right or wrong. The adjective scrupulous is from Latin scrūpulōsus, from scrūpulus, "scruple." A near synonym is punctilious.
