Grammar & Syntax Rules
Key Rules & Elimination Strategies
Semicolon Rule\text{Independent Clause} \; ; \; \text{Independent Clause}
Joins two complete sentences without a coordinating conjunction.
Colon Rule\text{Complete Independent Clause} \; : \; \text{Explanation / List / Item}
Everything before the colon must form a complete grammatical sentence.
Dangling Modifier Rule[\text{Introductory Modifier}], \; [\text{Actor being modified}] \dots
The subject right after the comma must be the one performing the introductory action.
Common Student Traps
- •Using a comma to join two independent clauses without a FANBOYS conjunction (comma splice).
- •Placing a colon after a verb or preposition (e.g. "such as:" or "consists of:").
- •Matching verbs with nouns in prepositional phrases rather than the true sentence subject.
Proven Study Strategies
- •Cross out prepositional phrases to isolate the simple subject and simple verb.
- •Remember that a period and a semicolon are grammatically identical on the SAT.
