Em dashes are one of the most frequently used types of dashes. They act as separators within a sentence, similar to parentheses or commas. Em dashes provide emphasis, set off additional information, or indicate sudden breaks or interruptions in thought. They are longer than hyphens and create a noticeable pause in the flow of text.

En dashes are shorter than em dashes and primarily used in range expressions. They denote a connection or relationship between two endpoints, such as dates, times, or numbers. En dashes can also represent connections in compound adjectives when multiple words are used, such as “New York-based” or “pre- and post-test.”

Hyphens are the shortest type of dash and often confused with dashes. However, they serve a distinct purpose as they connect words and parts of words. Hyphens are commonly used in compound words, to join prefixes and suffixes to base words, and in specific phrases like “twenty-one” or “six-time Grammy winner.”
