Summary: This resource offers a number of pages about comma use. For more information on semicolons, please see the "90-Second Semicolon" vidcast series on the Purdue OWL YouTube Channel. A group of words containing a subject and a verb and expressing a complete thought is called a sentence or an independent clause. Sometimes, an independent clause stands alone as a sentence, and sometimes two independent clauses are linked together into what is called a compound sentence. Depending on the circumstances, one of two different punctuation marks can be used between the independent clauses in a compound sentence: a comma or a semicolon. The choice is yours. Comma (,)Use a comma after the first independent clause when you link two independent clauses with one of the following coordinating conjunctions: and, but, for, or, nor, so, yet. For example: I am going home, and I intend to stay there. It rained heavily during the afternoon, but we managed to have our picnic anyway. They couldn't make it to the summit and back before dark, so they decided to camp for the night. Semicolon (;)Use a semicolon when you link two independent clauses with no connecting words. For example: I am going home; I intend to stay there. It rained heavily during the afternoon; we managed to have our picnic anyway. They couldn't make it to the summit and back before dark; they decided to camp for the night. You can also use a semicolon when you join two independent clauses together with one of the following conjunctive adverbs (adverbs that join independent clauses): however, moreover, therefore, consequently, otherwise, nevertheless, thus, etc. For example: I am going home; moreover, I intend to stay there. It rained heavily during the afternoon; however, we managed to have our picnic anyway. They couldn't make it to the summit and back before dark; therefore, they decided to camp for the night. For more information about compound sentence patterns, see the Purdue OWL handout on Sentence Punctuation Patterns. Punctuation within sentences can be tricky; however, if you know just a few of the following rules, you will be well on your way to becoming a polished writer and proofreader. Rule: Use a comma between two long independent clauses when conjunctions such as and, or, but, for, nor connect them. Rule: If the clauses
are both short, you may omit the comma. Rule: If you have only one clause (one subject and verb pair), you won’t usually need a comma in front of the conjunction. Rule: Use the semicolon if you have two
independent clauses connected without a conjunction. Rule: Also use the semicolon when you already have commas within a sentence for smaller separations, and you need the semicolon to show bigger separations. Rule:
A colon is used to introduce a second sentence that clarifies the first sentence. Rule: Use a colon to introduce a list when no introductory words like namely, for instance, i.e., e.g. precede the list.

When to use a semicolon instead of a comma in a list?Semicolons are not only used to link main clauses. They can also be used in complicated lists. Elements in a list are usually separated by commas. But if the elements themselves contain commas, semicolons are used to separate them.
When should a semicolon be used examples?When you have a conjunctive adverb linking two independent clauses, you should use a semicolon. Some common conjunctive adverbs include moreover, nevertheless, however, otherwise, therefore, then, finally, likewise, and consequently.
