Question

In the Russian Language what is the difference between E and э?

Answer 1

its absolutely different letters..:)

pronunciation is different..

"E" its more like  "yeah"

and  "э" its like the first sound in "ethnic"  

Answer 2

I believe the main difference between the two is palatalization (adding the Y sound before another sound)...

Е (е) is pronounce /je/, that is like the "ye" in "yet"*

Э (э) is pronounced /e/, like the "e" in "bed"*

*The IPA symbol for the vowel /e/ represents a sound that is not exactly like the E in "bed" or "yet", but more like the A in "play" before you get to that Y sound at the end.
