Sometimes, an independent clause stands alone as a sentence; sometimes two independent clauses are linked together into what is called a compound sentence. The choice of using a comma ( , ) or a semicolon ( ; ) is up to the writer. As a matter of style, however, one shouldn't use too many semicolons when a comma + conjunction would suffice. Additionally, do not substitute a comma for the conjunctive connector.
For example, the first sentence that I used could have had a comma instead of the semicolon, but a conjunction (and, or, but, et. al.) should not be omitted.
Exception: As a matter of style, you can do the second example (the one marked 'no') occasionally, when the style suits the mood. Still, this isn't to be done all the time.
In this example, you could easily see how 'and' could have fit nicely in the sentence.
Therefor, a semicolon is acceptable, although not necessary. It's a matter of taste, as is using semicolons in dialog. However, in APA-styled writing--and research and technical documents--semicolons should be used sparingly and with strict compliance to grammatical rules.
You can see how easily 'but' would fit in this sentence.
Should a comma have been placed before the conjunction 'but'? You wouldn't be considered wrong in American English (AE); however, British English (BE) tends to follow a more strict comma-rule in this instance. Since it is considered, then, a matter of style, the writer should simply consider consistency as her only criterion. That is to say, if she does it once, she should act similarly should the situation arise again.
You should also use a semicolon when you join two independent clauses together with one of the following conjunctive adverbs: however, moreover, therefore, consequently, otherwise, nevertheless, thus, and so forth.
For example:
In the latter sentence, you might be tempted to start with 'Since...'
That would be incorrect.
how you broke out "lamer" like it hadnt been played out by the first time you ever inserted a free 100 hour aol disc in your box.
