[Q]: Question: Possible Duplicate: Is it correct to use "punctuation outside of the quotations", or "inside?" I've heard that you should always place ending punctuation inside of quotes, no matter what. Are there any cases where it is appropriate for a sentence to end with ".? 
Answer: I was taught that if the quote has more than one sentence, then you do it like this, with a period in and a period out: Statement: I once heard a quote that said "Stop. You can't go. If you go, you can't stop. If you stop, you can't go.". Question: Is there a quote that says "Stop. You can't go. If you go, you can't stop. If you stop, you can't go."? That isn't a real quote, by the way. If it only has a phrase, or if it only has one sentence, then you do it like this: Statement: John said "Get out of here". Question: Did John say "Get out of here"?.
[A]: no


[Q]: Question: English isn't my mother tongue, and when we recently talked to a native speaker (during some company audit), he pointed out that the plural word "trainings" is actually wrong (he pointed that it is a very common mistake and was almost amused by it). I couldn't understand why and wondered what the correct plural of "training" would be. Online Dictionaries/Thesaurus don't answer it, so it's probably another opinion-based statement. I haven't found a source to back it up, though. 
Answer: Training is both countable and uncountable. Usually, referring to a process, it is uncountable and has no plural. It is sometimes used to mean "a specific training event", and is then countable, and has the plural "trainings". The OED has examples of this use going back to 1578, with the plural recorded from 1598.
[A]: yes


[Q]: Question: Is the following correct, or is there more to it? "I forgot his name" I knew his name, but I forgot it. "I forget his name" I keep forgetting his name. Where using "forget" basically means that you tried to remember this information before as well, but you couldn't then either. 
Answer: I forgot his name means I've permanently forgotten, while I forget his name means I've temporarily forgotten even though I expect to be able to remember. In a few more minutes I'll probably remember. See also the phrases "slipped my mind" or "the tip of my tongue".
[A]:
no
