So let’s have a review lesson together.
The Four Rules of Semicolon Usage
Rule #1 -Use to connect two independent clauses
ex: This is the first half of the sentence; this is the second half.
Note: if you use a conjunction (and, so, but, etc.) then you must use a comma
ex: This is the first half of the sentence, and this is the second half.
Rule #2 – Use as a “super-comma” when creating lists where the items are already using commas.
ex: We visited Moab, Utah; Los Angeles, California; and Eve, my grandma.
ex: The three important dates are Tuesday, May 21st; Friday, May 24th; and Saturday, May 25th.
Rule #3 – (optional) Use to clarify a complete sentence that ends in a connector word and then a list of three or more items.
ex: The conference will go on as planned; except George, Julie, and Jerry won’t be attending
OR, you can still use a comma:
ex: The conference will go on as planned, except George, Julie, and Jerry won’t be attending.
Rule #4 – (optional) Use to connect two independent clauses using a conjunction where the first clause already has a comma in it. Sometimes this makes the sentence easier to read.
ex: When I cook anything, it turns out bad; but you can still eat it.
Master rules 1 and 2; you can consider yourself a semicolon expert and use them with confidence!
