Overview
This lecture explains the essential rules for identifying and punctuating independent and dependent clauses, their connection with conjunctions, and the three core sentence structures tested on the ACT English exam.
Clause Types
- An independent clause is a complete sentence with a subject and verb (e.g., "It is cold").
- A dependent clause cannot stand alone and requires additional information to be complete.
- A subordinating conjunction (e.g., "even though," "after") makes a clause dependent.
- A dependent clause at the start or after a subordinating conjunction needs an independent clause to complete the sentence.
Conjunctions
- Subordinating conjunctions (like "even though" and "after") begin dependent clauses.
- Identifying these conjunctions helps spot dependent clauses in sentences.
Core Sentence Structures
- Structure 1: Dependent clause, comma, independent clause (e.g., "After we ate, we went to the library.").
- Structure 2: Independent clause, comma, dependent clause (e.g., "We went to the library, after we ate.").
- Structure 3: Independent clause, interjection or dependent clause set off by commas, rest of independent clause (e.g., "It is, surprisingly, raining outside.").
- Interjections or non-essential clauses can be removed without changing the core meaning.
Combining Structures & Examples
- Sentences can combine multiple structures: an introductory dependent clause, independent clause, and a conclusive dependent clause.
- Example: "Even though it is sunny, it is raining, which surprises me."
- Complex sentences often include interjections, introductory, and conclusive dependent clauses.
Key Terms & Definitions
- Independent Clause — A complete sentence with a subject and verb that can stand alone.
- Dependent Clause — An incomplete sentence that cannot stand alone and often starts with a subordinating conjunction.
- Subordinating Conjunction — A word (like "even though," "after") that introduces a dependent clause.
- Interjection — A phrase inserted into a sentence, set off by commas, that can be removed without affecting grammatical correctness.
