About the the pronunciation of "er" in prefixes and suffixes in german I always hear people saying "etwas verkaufen" oder "etwas verbrennen". Some pronounce "ver" as a diphthong, like a british would say the word "fair" and others pronounce it as a short "fa". Is this an accent peculiarity or is there just one way to say the "er" in "Vater", "Mutter" and "Verkäufer"?
