Vest or west
Vest
A sleeveless undershirt. Say: VEST — top teeth touch lower lip.
Aarav wore a cotton vest under his shirt.
West
The direction where the sun sets. Say: WEST — round lips, no teeth.
The sun sets in the west.
Remember: V: top teeth gently on lower lip and buzz. W: round your lips like a kiss, no teeth. Many Indian speakers use one sound for both — practise both.
