Remember that colons are not the same as semicolons. Placing a colon between two sentences will not always suffice. Never place a colon between a verb and its object or between a preposition and its object. Remember that when using a colon in a sentence, an independent clause must always precede the colon: what follows the colon can be a dependent clause, list, thought, or another independent clause. Always check to be sure colons and semicolons are properly used in papers.
