A semicolon is a very strong punctuation mark; it is more like a period than a comma. Semicolons are used in three places:

  • Between two sentences that are closely connected in idea.
  • Before conjunctive adverbs and some transitional phrases.
  • Between items in a series if the items already contain commas (Oshima 257).

I. Between Two Sentences:

A semicolon can be used instead of a period between any two sentences that are closely related in meaning. You could also use a period, but when the sentences are connected in meaning, it is better to use a semicolon. The term independent clause is the same as a sentence, as it must have a subject and a verb, and is a complete idea on its own.


Independent Clause ;
(A Sentence)
Independent Clause
(A closely related sentence)
Tomatoes are not vegetables; they are fruits.
I hope to do well on my final; my scholarship depends on a high GPA.
My cat never gets full; she could eat all day.


A semicolon is used between the two independent clauses of a compound sentence when they are not joined by a coordinating conjunction (for, and, nor, but, or, yet, so = FANBOYS).


Each of the sentences above could also be made into two separate sentences by replacing the semicolon with a period. Note that the first word after a semicolon is not capitalized (unless it is a proper noun).

II. Before Connectors:

Use a semicolon before conjunctive adverbs such as however, therefore, nevertheless, moreover, and furthermore; a semicolon can also be used before some transitional phrases such as for example, as a result, that is, in fact, etc. (Note that a comma follows the conjunctive adverb.)

Independent Clause ; Connector , Independent Clause
I've always wanted to go to London; however, I never have the money.
My friend doesn't know how to swim; therefore, she never goes to the beach.


The connector (conjunctive adverb) does not have to be placed immediately following the semicolon:

It was cold; therefore, we went inside.

It was cold; we, therefore, went inside.

It was cold; we went inside, therefore.


Here is a partial list of conjunctive adverbs:


Conjunctive Adverbs
consequently indeed nevertheless
furthermore in fact then
however moreover therefore

III. Between items in a series if the items already contain commas.

I cannot decide which instrument I like best: the cello, with its deep, sonorous tones; the piano, with its ability to play all kinds of music; or the guitar, with its portability and its haunting, plaintive chords.
