while vs vile: hear and say the difference
while and vile are identical except for one sound: while has the w sound, /w/, and vile has the v sound, /v/. W rounds the lips into a tight ring and glides, with the teeth nowhere near the lip; V rests the top teeth on the bottom lip and buzzes there without moving.

Why this pair is hard
Hindi, Urdu, Punjabi, Gujarati and Marathi have one sound covering both, so 'wine' and 'vine' are the same word. German and Russian pronounce w as v, so the error runs one way: 'wine' becomes 'vine'. Mandarin has w but no v, so the error runs the other way.
