Is !? a grammatically accepted form of emphasizing?

Question

That should be "an".

Answer 1

This combined punctuation is not generally accepted. There was--in the 1960's, if I recall accurately--an attempt to create a hybrid punctuation mark combining the question mark and the exclamation point. It was called an "interrobang," curiously enough. It never gained general acceptance and, thus, fell out of usage rapidly.

Answer 2

First '!?' is not used for emphasis.

It is an accepted form in modern English Writing!?

Perhaps, not in Documents or in court judgments or records or contract deeds.

In personal letters or mails, it can be used.

This '!?' is a clever way of putiing things. When the writer is not sure whether the statement he has made is True or not he uses '!?' at the end. It is like asking, 'I'm not sure. It is doubtful to me' & what about you?

Here are a couple of examples::

"No man has ever sexually satisfied a woman!? Ask any woman!".

'No man is fully satisfied with the sex he has had!? Ask any man!


Bold Statement moderated by / seasoned with a little doubt by using the punctuation mark '!?'.

Answer 3

You were right the first time - "a"
Using both question mark and exclamation point confuses a reader. You might use it for speech-making notes or casual communication, but not at other times. Besides, it looks weird.

Answer 4

No. Not in proper English. However, it has become accepted informally in email and chat.

You'll never see it in a proper business letter.

Answer 5

The interrobang (!?) is completely correct, but not as emphasis. It is an exclaimed question. For example, "Are you kidding me!?".

We won't see this in business letters, but you will see it in novels from time to time.
