Explanation: 1. Use a semicolon between two closely related independent clauses. 3. Use a comma before a coordinating conjunction such as <em>and, but, or, & yet. </em>4. Separate the two clauses into two sentences. Use a period at the end of the first sentence. Start the new sentence with a capital letter.

An infinitive composes the words "to" plus the "simple verb". Infinitives can be used as nouns, adjectives or even adverbs.

"decided".
