A question of grammar

[ladyinthemists]

Am I the only one bothered by such phrases as:
"Where you at?"
"If I would've known..."
and
"Grammar school"
just to name a few that I hear quite a lot.

I would have said:
"Where are you?"
"If I had known..."
or
"Elementary school" (to my knowledge there is no such thing as a school for grammar)

Am I wrong about this??? Or, is correct grammar a thing of the past?

Hello, ladyinthemists.

"Where you at?"
=> That one can be account for by phonetics. The missing verb are, when contracted (are => 're) is hard to pronounce after "Where" (Where're), so it's often either half pronounced and barely audible, or it's omitted altogether. We kind of know it's there though - I think.

The problem some people might have with "Where you at?" isn't the missing verb, but rather the fact that it ends with a preposition, "at".

"If I would've known..."
=> You know, I'd say, "If I had have known.

"Grammar school"
=> Isn't it synonymous with elementary school? Well, maybe not in the USA.

All the best.
