Do not use a semicolon in the following situtations:

*to introduce a list

Do not use a comma in the following situations:
*after a coordinating conjunction
*after ''such'' as or ''like''
*before ''than''
*after ''although''
*before a parenthesis
*to set off an indirect (reported) quotation
*with a question mark or an exclamation point (Hacker 249).
* between compound elements that are not independent clauses
* use a comma to seperate a verb from its subject or object
* use a comma before the first or after the last item in a series

* use a comma to set off a concluding adverb clause that is essential to the meaning of the sentence (Hacker 246-248).
