What is the purpose of em dash in writing?

Em dashes can be used in pairs to mark off additional information that is not essential to understand the sentence. Here they function similarly to parentheses or a pair of commas. An em dash is usually written without spaces on either side, although some style guides do recommend using spaces.

What effect does the use of em dashes have on the reading of a text?

The Em Dash: An Introduction

Like commas and parentheses, em dashes set off extra information, such as examples, explanatory or descriptive phrases, or supplemental facts. Like a colon, an em dash introduces a clause that explains or expands upon something that precedes it.

Why do em dashes make sentences more interesting to read?

Use an em dash to mark sharp turns in thought

Em dashes can also signal an interruption or a sudden change in the direction a writer was heading with a particular sentence. This technique is best suited for creative or informal writing. If you use it in academic writing, you might look unsure of yourself.

What is the effect of em dashes?

Em dashes are used to indicate a pause or an emphasis. They often take the place of many other punctuation marks, such as colons, commas, or parentheses. When used correctly, there is a subtle yet significant impact on the sentence. That is why writers love this little punctuation mark.
