A question mark (?) is used at the end of an interrogative sentence. It can also be used at the end of other sentences or phrases to indicate that they should be read with a questioning (i.e., rising) intonation.

Quotation marks always come in pairs. If there is an opening quotation mark, there must be a closing one. Quotation marks can be either curved/curly (sometimes called โsmartโ) or straight. If they are curved, opening and closing quotation marks curve in different directions.

An en dash (โ) is used to indicate number ranges (e.g., 2022โ2024), to show a connection or relationship (e.g., โthe BostonโNew York trainโ), and to connect certain compound adjectives (e.g., โa World War IIโera buildingโ).
The en dash is longer than a hyphen (-) but shorter than an em dash (โ). It is so named because, historically, it was about the same length as a typeset N.

TipThe em dash has been a part of human writing for a long time. However, it is sometimes associated with AI writing as it often appears in the ouputs of generative AI tools. If you’re concerned that your writing feels overly patterned or a bit too โAI-like,โ QuillBotโs Humanize AI tool can help refine your tone, balance your punctuation, and make your text sound effortlessly human.

A hyphen (-) is a punctuation mark that is used to connect words (or parts of words) that function together in a sentence or phrase (e.g., “old-fashioned,” “10-year-old,” “break-in”).
Hyphens are often used in compound adjectives, compound nouns, number phrases, and words with prefixes. There are many rules that govern their use, and it’s not always easy to know which words require a hyphen. QuillBot’s Grammar Checker can help you ensure you’re using hyphens correctly.
