  - Have a subject and a verb.
  - Example: She reads books.
2. Compound Sentences
  - Consist of two or more independent clauses.
  - Coordinating conjunctions (FANBOYS – For, And, Nor, But, Or, Yet, So) connect them.
  - Example: She reads books, and she writes stories.
3. Complex Sentences

Parts of a Complex Sentence
1. Independent Clause (Main Clause)
  - Can stand alone as a complete sentence.
  - Example: She went to the market.
2. Dependent Clause (Subordinate Clause)
  - Cannot stand alone and depends on the main clause.
  - Example: Although it was raining (incomplete without the main clause).
3. Subordinating Conjunctions
  - Words that connect dependent clauses to independent clauses.
  - Examples: Because, Although, Since, Unless, While, If, Even though.
  - Example: Because she was hungry, she ate a sandwich.

Adverbial Clauses
- Modify verbs, adjectives, or other adverbs.
- Answer questions like how, when, where, and why.
- Example: She stayed inside because it was raining.
- Key subordinating conjunctions: Because, Although, While, If, When, Since.
Adjective Clauses (Relative Clauses)
- Modify nouns and pronouns.
- Introduced by relative pronouns (who, whom, whose, which, that).
- Example: The book that she borrowed was interesting.
Noun Clauses
- Function as a subject, object, or complement.
- Introduced by words like what, that, whether, how, why.
- Example: What she said surprised everyone.

Steps to Forming a Complex Sentence
- Identify the main idea (independent clause).
- Decide on the additional information to include (dependent clause).
- Choose the appropriate subordinating conjunction.
- Arrange the sentence to ensure clarity and coherence.
- Example: Even though she was tired, she finished her homework.
Common Mistakes in Complex Sentences
- Fragment Sentences: Using only a dependent clause without an independent clause.
  - Incorrect: Although she was tired.
  - Correct: Although she was tired, she continued working.
- Comma Splices: Incorrectly joining two independent clauses with a comma instead of a conjunction.
  - Incorrect: She was tired, she went to bed early.
  - Correct: She was tired, so she went to bed early.
- Run-On Sentences: Joining multiple clauses improperly.
  - Incorrect: She was tired she went to bed early.
  - Correct: Because she was tired, she went to bed early.

Using Different Sentence Types
- Avoid repetitive sentence structures to maintain reader engagement.
- Example:
  - Simple: She loves painting.
  - Complex: Since she loves painting, she practices daily.
  - Compound-Complex: Since she loves painting, she practices daily, and she hopes to become an artist.
Techniques to Improve Sentence Structure
1. Using Conjunctive Adverbs (However, Therefore, Moreover, Consequently)
  - Example: She was tired; however, she continued studying.
2. Parallel Structure
  - Keeping similar grammatical structures in a sentence.
  - Incorrect: She likes reading, to write, and painting.
  - Correct: She likes reading, writing, and painting.
3. Inversion for Emphasis
  - Changing word order for emphasis.
  - Example: Rarely do we see such dedication.
4. Using Appositive Phrases
  - Renaming a noun for clarity.
  - Example: My teacher, a strict but kind person, encourages us to write well.
