כְּסִיל

בַּעַר baʻar · H1198 · dull, stupid, coarse

Both the target term and בַּעַר (baʻar, H1198) ('brutish') denote foolish persons or qualities within the specific semantic field of folly. The target term is far more common than בַּעַר and carries additional, unrelated senses (celestial bodies, location names), but the core sense of foolishness genuinely overlaps between the two, supporting a real, if not identical, near-synonym relationship.

ἄφρων áphrōn · G878 · foolish, senseless, unwise

Greek ἄφρων (áphrōn, G878) (properly 'mindless,' hence 'stupid,' 'ignorant,' 'rash,' or 'morally unbelieving') renders Hebrew כְּסִיל as the standard Septuagint equivalent for 'fool,' with primary focus on moral and intellectual folly — mindlessness, rashness, and unbelief. It is the dominant rendering across passages, particularly in Proverbs and Ecclesiastes, where the Hebrew term denotes one who lacks wisdom or sound judgment.

ἀπαίδευτος apaídeutos · G521 · uneducated, foolish, ignorant
