Comma Usage in Compound and Complex Sentences
Use commas to separate independent clauses in compound sentences, especially when joined by conjunctions like "and", "but", "or", "so", "for", "nor", "yet", and "because".
Rules:
- Rule 1: Use a comma before a coordinating conjunction (FANBOYS) in a compound sentence. Example:
Scrooge was wealthy, but he was miserly.
- Rule 2: Use a comma after introductory elements in complex sentences. Example:
When Scrooge saw the ghost, he was frightened.
- Rule 3: Do not use a comma if the clauses are short and closely related. Example:
Scrooge smiled and laughed.
- Rule 4: Use commas to separate items in a list. Example:
Scrooge was greedy, selfish, and unkind.
