Comma vs. Semicolon: What's the Difference?
Comma is a punctuation mark used to indicate a pause or separation in a sentence. Semicolon is a punctuation mark used to link independent clauses or separate items in a complex list.
A comma is used to separate elements within a sentence, such as items in a list. A semicolon is used to connect closely related independent clauses without a conjunction.
Commas are often used after introductory elements or to set off clauses and phrases. Semicolons can separate items in a list where the items themselves contain commas.
Overuse of commas can lead to run-on sentences; they should not join independent clauses alone. Semicolons provide a stronger pause than a comma but less than a period, often clarifying complex sentences.
Commas are more common in everyday writing and are essential for clarity. Semicolons are less common and can be replaced by a period or conjunction in many cases.
