How many spaces should you insert after a semicolon?

In standard writing practice, when using a semicolon, it is customary to insert one space after the semicolon. This spacing aids in readability and helps to clearly distinguish the separation between closely related independent clauses. The semicolon functions to connect two thoughts without using a conjunction, and the single space following it allows for a smooth transition into the next part of the sentence.

Using one space after a semicolon also aligns with contemporary typing and formatting conventions, promoting a clean and professional appearance in written communication. This practice reflects modern writing style guidelines, ensuring clarity and coherence in text. While there might be historical variations in spacing preferences, especially in typewritten documents where two spaces were once common after periods, the current standard emphasizes one space following all forms of punctuation, including semicolons.
