Question Mark (?)
The question mark (also known as an interrogation point, interrogation mark, question point, query, or eroteme), is a punctuation mark that replaces the full stop (period) at the end of an interrogative sentence. For example:
- What is the meaning of punctuation?
- How much money did you transfer?
The question mark is also used in question tag. For example:
- You're French, aren't you?
- Snow isn't green, is it?
- He should go and see a doctor, shouldn't he?
The question mark is still used in an interrogative sentence which is transformed into a statement. For example:
- You don’t really believe that?
- Are you crazy?
But the question mark is not used for indirect or reported questions as explained in full stop.
