An em dash (โ) is a punctuation mark longer than an en dash and about the width of an uppercase letter โM.โ It is used to indicate a break in thought, create emphasis, or set off parenthetical statements. The em dash has several specific uses in written language:
- Interrupting Thoughts or Adding Emphasis: The em dash can set off a phrase or clause that interrupts the flow of the main sentence.
Example: The meetingโscheduled for next weekโhas been postponed. - Setting Off Parenthetical Statements: Em dashes can be used in pairs to set off parenthetical statements, providing additional information or clarification.
Example: The new softwareโdesigned for efficiencyโwill be released next month. - Creating Strong Emphasis: Em dashes can create strong emphasis, similar to colons or parentheses.
Example: The decision was clearโit had to be made immediately.
