What is a sentence?

"A sentence is a unit of language charecterized in most languages by the presence of a finite verb" (wikipedia). Sentences are classified two ways: according to their structure (simple, compuond, complex, and compound-complex) and according to their purpose (declaritive, imperative, interrogative, and exclamatory) (Hacker 463).

Structure

• Simple sentence: A Simple sentence is one independent clause with no subordinate clauses.

• Compound sentence: A compuond sentence is composed of two or more independent clauses with no subordinate clauses. The independent clauses are usually joined with a comma and a coordinating conjunction (and, but , or, not, for, so, yet) or with a semicolon.

• Complex sentence: A complex sentence is composed of one independent clause with one or more subordinate clauses.

• Compound-complex sentence: Still working
