1. Complex sentences are made up of two or more . 2. An clause can be a sentence.
3. A clause cannot be a sentence.

 An independent clause  contains a subject, a verb, and a complete thought.

       A dependent clause contains a subject and a verb, but no complete thought.

1. A SIMPLE SENTENCE has one independent clause.

Punctuation note:  NO commas separate two compound elements (subject, verb, direct object, indirect object, subjective complement, etc.) in a simple sentence.

2. A COMPOUND SENTENCE has two independent clauses joined by

       A.  a coordinating conjunction (for, and, nor, but, or, yet, so),

       B.  a conjunctive adverb (e.g. however, therefore), or

       C.  a semicolon alone.

   Punctuation patterns (to match A, B, and C above):

       A. Independent clause, coordinating conjunction  independent clause.

       B. Independent clause; conjunctive adverb, independent clause.

       C. Independent clause; independent clause.

3. A COMPLEX SENTENCE has one dependent clause (headed by a subordinating conjunction or a relative pronoun ) joined to an independent clause.

   Punctuation patterns (to match A, B, C and D above):

       A.  Dependent clause,  independent clause

       B.  Independent clause  dependent clause

       C.  Independent,    nonessential dependent clause,     clause.

       D.  Independent    essential dependent clause     clause.

4. A COMPOUND-COMPLEX SENTENCE has two independent clauses joined to one or more dependent clauses.

Punctuation patterns:

Follow the rules given above for compound and complex sentences.

A compound-complex sentence is merely a combination of the two.

CONNECTORS--COMPOUND AND COMPLEX SENTENCES

Two independent clauses may be joined by

   1.  Coordinating conjunctions  (FANBOYS)         Ic,  and    ic

   2.  Conjunctive adverbs       Ic;    therefore,     ic.

A dependent (subordinate) clause may be introduced by

   1. Subordinating conjunctions (ADVERB CLAUSE)     Dc, ic.   or    Ic dc.

   2. Relative pronouns (ADJECTIVE CLAUSE)  I, dc,  c.    or      I  dc  c.

  3.  Relative pronoun, subordinating conjunctions, or adverbs (NOUN CLAUSE)

Explanation:

1. Independent or dependent clauses

2. Independent

3. Dependent

Explanation:

Independent clauses are full thoughts that don't need anything else to convey a message.

Dependent clauses are sentence fragments, they have a subject and a verb, but it isn't a complete thought.
