Scrupulous and its close relative scruple ("an ethical consideration or principle") come from the Latin noun scrupulus, the diminutive of scrupus. Scrupus refers to a sharp stone, so scrupulus means "a small sharp stone." Scrupus retained its literal meaning but eventually also came to be used with the metaphorical meaning "a source of anxiety or uneasiness," the way a sharp pebble in one's shoe would be a source of pain. When the adjective scrupulous entered the language, it meant "principled," but now it also commonly means "painstaking" or "careful."
careful implies attentiveness and cautiousness in avoiding mistakes.
a careful worker
meticulous may imply either commendable extreme carefulness or a hampering finicky caution over small points.
meticulous scholarship
scrupulous applies to what is proper or fitting or ethical.
scrupulous honesty
punctilious implies minute, even excessive attention to fine points.
punctilious observance of ritual
