How is the ending -ig pronounced, and where?
My parents were from Vienna and for years I heard them pronounce words such as zwanzig, fertig, notwendig etc., by ending in "ich" rather than in "ick."
Most often nowadays, I hear "zwanzick", "fertick", "notwengick," rather than "zwanzich", "fertich" and "notwendich."
Can someone please explain the distinctions?
