The quality of being loyal, faithful, and unchanging over a long period of time.
From Latin 'constantia,' derived from 'constans' meaning 'standing firm' or 'steadfast.' The Romans valued this virtue highly, and it evolved through Old French into English as a measure of reliability and devotion.
During the Middle Ages, 'constancy' became one of the highest virtues—knights and lovers would swear oaths of constancy to prove they wouldn't abandon their cause or beloved, which is why you'll see it everywhere in love poetry and chivalric tales.
