Prior means before in time, not in place.

"...throw out some extremely improper English around me and I will not even waste my time getting to know you."

Promise?

"Might Could" is a great expression that follows the edicts of the likes of Orwell and Strunk and White about not using unnecessary words. It has two words less than "might be able to". (Oh dear, should that have been "fewer" words?) I'll stick with the "less" which has the advantage of being perfect English despite what some ignoramuses will tell you.

PS if we can talk of a big exaggeration as opposed to a small exaggeration why can't we qualify the word in other ways?

For a political party to exaggerate the benefits of their policies would be normal. But if they exaggerated said benefits beyond what even the most gullible of the populace on the loose could take seriously, that would be an over-exaggeration.

So there you are:

An exaggeration is a lie; but an over-exaggeration is an implausible lie.

Plausible?

If you are doing a test, "correct" is what your teacher says is correct. Otherwise it is not a very useful word in the context of a living language.

There is no official grammar of English, and no academy or central authority to tell us what is correct or not, so usage reigns.

With newish terms, when there is not enough experience to establish some sort of convention (or standard), the best we can do is make a guess at what our audience will most approve of.

Unless of course they are the sort of people who do not approve of prepositions at the end of sentences, when we do well to ignore them.
