Periodic Sentence: A sentence that presents its central meaning in a main clause at the end. The independent clause is preceded by a phrase or clause that cannot stand alone. For example, "Ecstatic with my AP scores, I let out a loud shout of joy!" The effect of a periodic sentence is to add emphasis and structural variety.

sentence that is not grammatically complete until its end. Periodicity is accomplished by the use of parallel phrases or clauses at the opening or by the use of dependent clauses preceding the independent clause; that is, the kernel of thought contained in the subject/verb group appears at the end of a succession of modifiers. It is the opposite of a nuclear sentence. The periodic sentence is effective when it is used to arouse interest and curiosity, to hold an idea in suspense before its final revelation.

Example:
 * John,** the tough one, the sullen kid who scoffed at any show of sentiment, **gave his mother flowers.**

Example: Suddenly, for no apparent reason, **the** loveable **cat scratched** **Sally.**

Example:
 * Love**, as everyone knows except those who happen to be afflicted with it, **is blind**.

Loose Sentence: a type of sentence in which the main idea (independent clause) comes first, followed by dependent grammatical units such as phrases and clauses. If a period were placed at the end of the work containing many loose sentences, the work often seems informal, relaxed, and conversational.

Example: He went into town to buy groceries, to visit his friends, and to go to the bookstore.
