Key Concepts & Vocabulary
TermDefinitionExample
Independent Clause (IC)A group of words containing a subject and a verb that expresses a complete thought. It can stand alone as a sentence.Antigone defied the king's decree.
Dependent (Subordinate) Clause (DC)A group of words containing a subject and a verb that does not express a complete thought. It cannot stand alone and often begins with a subordinating conjunction (e.g., because, although, when) or a relative pronoun (e.g., who, which, that)....because she believed in divine law.
Restrictive ElementA clause or phrase that is essential to the meaning of the sentence. It identifies or limits the noun it modifies and is NOT set off by commas.The god who ruled the underworld was named Hades. (The clause is needed to identify which god we mean.)

Key Rules & Conventions
The Clause Counting Formula
Simple = 1 IC | Compound = 2+ ICs | Complex = 1 IC + 1+ DCs | Compound-Complex = 2+ ICs + 1+ DCs
After identifying all clauses, use this formula to classify the sentence. Remember that both restrictive and nonrestrictive clauses count towards the total.
The Comma Test (for Nonrestrictive Elements)
If you can remove the element without changing the fundamental meaning or identity of the subject, it is nonrestrictive and must be enclosed in commas.
Use this as a quick check. If the sentence becomes vague or nonsensical without the element, it's restrictive and needs no commas.
The 'That' vs. 'Which' Convention
In formal writing, 'that' introduces restrictive clauses (no commas), while 'which' introd...

The sentence 'The protagonist, a character of immense complexity, drives the novel's plot' is classified as simple. Why does the presence of the nonrestrictive element 'a character of immense complexity' not make the sentence complex?
A.Because the element is restrictive, not nonrestrictive.
B.Because the element is essential to the sentence's meaning.
C.Because the element is a dependent clause.
D.Because the element is an appositive phrase, not a clause with a subject and verb.
Challenging
Consider the unpunctuated sentence: 'My brother who lives in Cairo is an archaeologist.' Depending on the author's intent, how could this sentence be classified?
A.It can only be complex, regardless of punctuation.
B.It could be simple (if 'who lives in Cairo' is a phrase) or complex (if it's a clause).
C.It could be compound (if a comma is added before 'who') or complex (if no comma is added).
D.It is complex, but the meaning changes depending on whether the clause is restrictive or nonrestrictive.
Challenging
