I wonder if we need to use a question mark following “I wonder” for requesting something.
For example: I was wondering if you’d like to come to the cinema with me this evening?
Is using the question mark correct here?
Answer
Maybe, but I wouldn’t, since the question “I was wondering if you’d like to come to the cinema with me this evening” is indirect. You can give it the overt form of a question by using auxiliary inversion with rising intonation: “I was wondering would you like to come to the cinema with me this evening?”, and then the question mark is okay.
