For some time now, I've noticed that non-ending "T" sounds are being left out of words, in favor of an abruptly stopped "h". I think it probably began in urban hispanic communities (that's what I associate it with, anyway) with "wha' evah". I just heard a news field reporter though, using it in most of her words, including "Manha' an" (Manhattan - this on NY1 tv station).
I'm curious, is anyone else noticing this trend? Is it just an urban thing? Just east coast? Any clearer ideas on origin?
