Meaning
Said when a surprising or unwelcome experience has just taught you something you didn’t know before.
It carries a philosophical shrug — mild resignation that mistakes and surprises are simply part of gaining experience, rather than something to dwell on.
Origin
The sentiment that lived experience is the truest teacher is ancient and cross-cultural — the Roman philosopher Seneca wrote in his “Epistulae Morales” that “as long as you live, you must keep learning how to live” — but the claim that the specific English phrase “live and learn” traces directly to Aelfric’s Colloquy, an Old English teaching dialogue written around 1000 AD to help students learn Latin, is not well supported: that text predates Modern English by centuries, and no fixed proverb in that exact wording is documented from it. The proverb in recognizably modern English is better traced to 16th-century English proverb collections, in the same tradition as John Heywood’s 1546 compilation of common sayings, several centuries after Aelfric.
