Common mistake
"All our work was vane" when meaning useless or unsuccessful (correct: in vain). Or "He is so vane about his looks" when meaning conceited (correct: vain).
Trick to remember it
'Vain' contains AI — like the letter I (ego). Vain people are full of I, obsessed with themselves. 'Vane' rhymes with 'plane' and 'lane' — things that move or indicate direction.
Quick rule
Is it conceited or unsuccessful (in vain)? 'Vain'. Is it the wind direction device or turbine blade? 'Vane'.
Did you know?
Carly Simon's 'You're So Vain' (1972) famously kept its subject a secret for decades. Simon eventually confirmed the second verse was about Warren Beatty. Both 'vain' and 'vanity' trace back to Latin 'vanus' (empty, without substance) — the idea that vanity is a hollow preoccupation. A 'weather vane' gets its name from Old English 'fana' (flag or banner) — the first vanes were literally flags showing wind direction.
