Five Common Grammar Mistakes People Make

I'm not a grammar expert, however these are common grammar mistakes I've seen which drove me to several grammar books to find what is and isn't correct. Now I'll pass that knowledge on to you.

Grammar mistake number one: If you are an American writer or want to be published in an American magazine, then the rule is periods and commas always go inside the quotation marks with only a couple of exceptions. (This rule does not apply to any other punctuation marks.)

Wrong: I rode in his "truck".
Correct: I rode in his "truck."

Wrong: We named the dog "Ralph", but he doesn't respond to it.
Correct: We named the dog "Ralph," but he doesn't respond to it.

The exceptions:

In certain scholarly and science disciplines this rule does not apply. The British do not follow this rule, either.

For letters and numbers, periods and commas go outside the quotation marks:

Go to gate "5". However: Go to gate "five."
He can't pronounce "w".

He went to gate "5", but no one was there.
We ought to teach him how to pronounce "w", but it's unknown how.

Grammar mistake number two: Me and my boyfriend went to the beach, is incorrect. You wouldn't say, Me went to the beach, so why say, Me and my boyfriend.... A way to correct this is to put the person you did whatever with first. It becomes harder to say, My boyfriend and me went to the beach, because when you say, ...me went to the beach, it won't sound right and you will automatically think, I went to the beach. Then you will say it correctly. My boyfriend and I went to the beach. (Me and (whoever)... is gaining more and more acceptance and may someday be considered proper grammar.)

Grammar mistake number three: There is no such word as alot. This may come about in the future since a lot of people use it, but right now, you won't find it in the dictionary. Nor will you find its'. Its is the possessive form of it. It's is the contraction of it is or it has and any other use is wrong.

Grammar mistake number four: Never place a comma or period after an explanation point or question mark.
