Origin
From Latin sagax (wise, keen-scented), related to sagire (to perceive keenly).
History
English took sagacious in the early 1600s for sharp understanding, not only book learning. It often described leaders, judges and animals credited with keen sense. The root ties wisdom to acute perception, which is why the word still suggests insight rather than mere cleverness. It remains useful when smart feels too thin.
