You can refer to my favorite teacher ever on YouTube, where he explain different between vain, vein, and vane in
abundant way
- VAIN = Terribly proud of themselves or worthless without value have no real substance.
- VEIN = This is a tube that carries the blood down your arm (you can see the veins) or mood.
- VANE = can be weather vane (look at the picture) or fins of a propeller
