Users expect direct questions and requests to end with a question mark. Indirect questions, commands and rhetorical questions can take other punctuation.
Question marks usually go after the last letter in a sentence
Like other punctuation marks, question marks stay with the text they refer to. Usually, this is immediately after the last letter of the last word of the sentence.
Brackets and quotation marks change the position of question marks
For brackets and quotation marks, place the question mark:
- before a closing bracket or quotation mark if the question is part of the text in the brackets or quotation marks
- after the closing bracket or quotation mark if the question is part of the surrounding text.
Question mark before the closing bracket or quote
She asked, ‘Is the report due on Tuesday
They decided (and why wouldn’t they
?) to cancel the program.
Question mark after the closing bracket or quote
What did she mean by ‘the report is due ASAP’
Did they decide to cancel the program (the EDTA program)
Inserted question marks can show uncertainty
Question marks can express doubt and uncertainty about dates or other specific details.
John Limeburner (
?1743–1785) was a convict who arrived in Australia on the First Fleet.
Pery Baylee (1784–
?) was commandant of Macquarie Harbour penal station in Van Diemen’s Land from 1831 to 1833.
Direct questions and requests end in a question mark
Direct questions end with a question mark. Most begin with one of these words:
- ‘who’, what’, ‘when’, ‘where’, ‘why’, how’, ‘which’, ‘whose’
- ‘are’, ‘is’, ‘was’, ‘were’
- ‘has’, have’
- ‘did’, ‘do’, ‘does’
- ‘can’, ‘will’, ‘could’, ‘would’, ‘should’, ‘might’.
These types of questions are called interrogative sentences.
- Who will attend the meeting next week
- Whose turn is it to take the minutes
- Are you ready to start the meeting
- Have they finished voting
- Did you attend the meeting
- Will the new government deliver a budget surplus
- Could you please make your changes by tomorrow
Some sentences don’t start with one of the words such as ‘who’, ‘could’ and ‘does’ but still end with a question mark.
That’s your proposal
Sometimes questions are tagged on to the end of another clause.
They would say that, wouldn’t they
Requests are often framed as questions. Requests suggest that people have the option of saying ‘no’.
- Can you consider who your future colleagues might be?
- Can you please upload your edits?
Indirect questions and commands don’t use a question mark
Indirect questions don’t end with question marks, even if they include a word such as ‘who’ or ‘does’.
He asked who will attend the meeting next week.
Indirect questions are often used in headings.
- Who we are [Heading]
- How to submit a claim [Heading]
To turn indirect questions into direct questions you can:
- rearrange the words so the verb comes before the subject
- introduce a word such as ‘can’ or ‘why’ – but make sure there is a subject.
Spellcheckers often recommend that you change indirect questions to end with a question mark. This isn’t always correct. It depends on whether you are asking a question.
Instructions and commands aren’t framed as questions. They don’t start with words such as ‘what’, ‘are’ or ‘does’, and don’t end with a question mark.
Commands and instructions don’t suggest that people have a choice.
- Consider who your future colleagues might be.
- Please upload your edits.
Rhetorical questions end in a question mark or exclamation mark
Depending on the context, a rhetorical question can end in a question mark or an exclamation mark. Exclamation marks add emphasis – this can make a rhetorical question sound blunt.
- Will you ever stop asking questions
- Will you ever stop asking questions
The digital edition has targeted advice on how to use a question mark. It has the same information as the sixth edition but provides more examples to help users.
The Content Guide had no specific guidance about question marks.
