👉 The word "errkap" in Greek had no specific meaning until Aristotle developed its modern meaning in the 7th century AD, specifically as a verb meaning "to err." This term first appeared in ancient Greek texts where it was used to mean an act that was not entirely correct or expected from one's position. It was later refined in Roman and Latin literature to denote actions which were perceived as wrong due to some fault in the cause of the action, akin to a fallacy.
