Umm.. no. That’s just incorrect on all levels. Ask is ask, library is library, spaghetti is spaghetti, Massachusetts is Massachusetts. Anyone who says otherwise isn’t saying the word properly.
Note: This is different than the “envelope” and “potato” thing. Those can be pronounced differently, but still said right. Ask and aks aren’t the same.
Yes, this is a pet peeve of mine. It also bugs me when my friend says “whats if” instead of “what if” and yes I do correct her every time. Now she corrects herself. =]
