Vain, Vane or Vein: Which Is Correct?
Vain means conceited, or futile. A vane is a flat blade that turns in the wind. A vein carries blood.
too vain to admit it. a weather vane. a vein in his wrist.
The test that settles it
Three different jobs, so ask what kind of word you need. Describing a person or an effort? Vain. Naming a blade on a roof or a windmill? Vane. Anything running through a body, a rock or a piece of marble? Vein.
“all our work was in ___” → futile, so vain.
“a ___ of silver in the rock” → a seam running through, so vein.
Vain has an i standing up in the middle, and vanity is all about I. Vane rhymes with plane, and a vane is a flat plane of metal. Vein keeps the odd ei — the one inside you.
Vain: conceited, or futile
Two senses that share an idea of emptiness: excessively proud of your appearance, or producing no result. The second survives mostly in the fixed phrases in vain and vain attempt.
He is vain about his hair.
a vain attempt to restart it
They searched in vain.
Is it pride, or wasted effort? Then vain.
Vane: a flat blade
The pointer on a roof that swings to show wind direction, and by extension any flat blade that turns — on a windmill, a turbine, or a feather.
a copper weather vane
the vanes of the turbine
the vane of a feather
Is it a flat blade that turns? Then vane.
Vein: a vessel, a seam, a mood
A blood vessel returning blood to the heart; a seam of ore or a line in marble or a leaf; and figuratively a manner or mood — in a similar vein.
a vein standing out on his temple
a rich vein of copper
more jokes in the same vein
Does it run through something? Then vein.
Side by side
| Vain | Vane | Vein |
|---|---|---|
| Conceited, or futile | A flat blade | A vessel or seam |
| Adjective | Noun | Noun |
| in vain | weather vane | in the same vein |
| The i is for I | Rhymes with plane | Has the odd ei |
The exceptions
The futility sense is older than the pride sense and both come from Latin vanus, empty. Take a name in vain means to use it emptily — not to be proud of it.
Only vein has a widely used abstract sense: in a lighter vein, a rich vein of form. If the sentence is about a manner, style or run of something, it is vein every time.
