An archaic or obsolete term possibly related to scrupulousness or a small pebble; extremely rare and difficult to verify.
Potentially from Latin scrupulus (small sharp stone, source of the word scruple), but this word is so obscure that its true origin is uncertain.
This word is so rare that it barely appears in historical records—it's a reminder that not every word in the oldest dictionaries actually had widespread use, and some were included based on a single manuscript mention.
