What are Main and Subordinate Clauses?

Before diving into the worksheets, let's establish a clear understanding of the core concepts. A clause is a group of words containing a subject and a verb. The key difference lies in their independence:

• Main Clause (Independent Clause): A main clause expresses a complete thought and can stand alone as a sentence. It contains a subject performing an action (or being in a state of being).

Example: The dog barked loudly. (Subject: dog; Verb: barked)

• Subordinate Clause (Dependent Clause): A subordinate clause does not express a complete thought and cannot stand alone as a sentence. It relies on a main clause for its meaning and is often introduced by a subordinating conjunction (e.g., because, although, since, if, when, while, after, before, until, as) or a relative pronoun (e.g., who, whom, whose, which, that).

Example: because the mailman rang the doorbell. (This needs a main clause to complete the thought).

Types of Subordinate Clauses

Subordinate clauses can be further classified into different types based on their function within a sentence:

• Adjective Clauses: These clauses modify nouns or pronouns, functioning like adjectives. They often begin with relative pronouns (who, whom, whose, which, that).

  Example: The house, which is on the hill, is very expensive. (modifies "house")

• Adverb Clauses: These clauses modify verbs, adjectives, or other adverbs, functioning like adverbs. They often begin with subordinating conjunctions (because, although, since, if, when, while, after, before, until, as).

  Example: He went home because he was tired. (modifies "went")

• Noun Clauses: These clauses function as nouns in a sentence. They can act as subjects, objects, or complements. They often begin with words like that, what, whoever, whomever, wherever, whenever.

  Example: I know that he is honest. (acts as the object of the verb "know")

Complex Sentences and Punctuation

Mastering main and subordinate clauses is crucial for constructing complex sentences. Here's the thing — commas are generally used to separate a subordinate clause from a main clause, particularly when the subordinate clause precedes the main clause. A complex sentence contains at least one main clause and one subordinate clause. So naturally, proper punctuation is vital when combining clauses. If the subordinate clause follows the main clause, a comma is sometimes omitted, especially with short, simple clauses.

Example with comma: Because it was raining, the game was canceled.

Example without comma: The game was canceled because it was raining.

Worksheet 4: (This requires more in-depth analysis identifying clause types and functions; answers will vary slightly depending on the analysis)

These answers will need to be more detailed than the preceding worksheets. They require identification of each clause, its type (adjective, adverb, noun), and its function in the larger sentence. Take this: for sentence 1:

1. Main Clause: the hikers continued their journey Subordinate Clause 1 (Adverb): Although the weather was terrible Subordinate Clause 2 (Adverb): because they were determined to reach the summit before nightfall Subordinate Clause 3 (Adverb): even though it was risky

The analysis should continue in this manner for each sentence, identifying the function of each clause within the sentence. Consider this: due to the length and complexity of detailed answers for Worksheet 4, providing a concise answer key would be insufficient and potentially misleading. Independent analysis and understanding are key to success on this worksheet.
