Inverted commas, or quotation marks, is a form of punctuation that is primarily used when quoting a statement from a person. Here's an example: "Why am I such a loser?"
If you can't explain it simply, you don't understand it well enough -- Albert Einstein
Other forms of punctuation and quotation marksEdit
If you're going to end your sentence and you have a quote behind, if that form of punctuation is apart of the quote, you put it in the quote but if your [insert punctuation mark here] isn't apart of it, then you don't.
