What Are Question Marks? (Punctuation Lesson)

A question mark is used to indicate the end of a question. For example:

Question Marks to Show Inflection

Occasionally, in informal writing, a question mark can be used to turn a statement into a question. The question mark tells the reader to add question inflection to the sentence. For example: Question marks are also used for statements transformed into questions by inflected words or question tags at the end. For example:

Inflected Words Question Tags Read more about questions (interrogative sentences).

Using (?) For Uncertainty

Sometimes, in informal writing, a question mark in brackets is used to express uncertainty. For example: Note: Using (?) is lazy. Avoid it in formal documents.

Be Mindful of Indirect Questions

An indirect question is a question embedded inside a statement (i.e., a declarative sentence) or another question (i.e., an interrogative sentence).

A Polite Request Dressed Up As a Question

Often, a polite request comes in the form a question. There is a lot of leniency on whether such a sentence is ended with a question mark or a full stop / period. For example:

Be Mindful of Questions That Look Like Statements

The Inverted Question Mark
