1. Introduction to Sentence Structure

• Sentence structure refers to the arrangement of words, phrases, and clauses to form meaningful and grammatically correct sentences.
• It determines clarity, coherence, and effectiveness in writing and speaking.
• Good sentence structure enhances readability and avoids ambiguity.

2. Types of Sentences

2.1 Simple Sentences

• Contains only one independent clause.
• Has a subject and a predicate.
• Expresses a complete thought.
• Examples:
  • “She reads every day.”
  • “The sun is shining.”
• Tricks to Identify:
  • One subject and one verb.
  • No additional dependent clauses.
• Common Mistakes:
  • Fragments (e.g., “Running in the park.”)
  • Missing verbs or subjects.

2.2 Compound Sentences

• Made up of two or more independent clauses joined by a coordinating conjunction or a semicolon.

  • Incorrect punctuation.

3. Sentence Components

3.1 Subjects and Predicates

• Subject: The main noun or pronoun the sentence is about.
• Predicate: The part of the sentence that tells what the subject does.
• Examples:
  • “The dog (subject) barks loudly (predicate).”
  • “She (subject) is reading a book (predicate).”

3.2 Objects and Complements

• Direct Object: Receives the action.
  • Example: “He kicked the ball.”

4. Sentence Errors & How to Fix Them

4.1 Sentence Fragments

4.2 Run-on Sentences

• Fix: Use a period, semicolon, or conjunction.
• Example (Incorrect): “She loves music she plays the piano.”
• Example (Corrected): “She loves music. She plays the piano.”

4.3 Comma Splices

• Two independent clauses joined by a comma instead of a conjunction.
• Fix: Use a semicolon, conjunction, or period.

• Example (Corrected): “I was late because my bus was delayed.”

5. Punctuation in Sentence Structure

5.1 Periods, Commas, and Semicolons

• Period (.) Ends a complete sentence.
• Comma (,) Separates clauses, lists, or extra information.
• Semicolon (;) Links closely related independent clauses.
• Example: “She loves books; she reads daily.”

5.2 Colons and Dashes

• Colon (:): Introduces lists, explanations, or elaborations.
• Dash (—): Adds emphasis or interruption.
• Example: “She had one dream: to travel the world.”

6. Parallelism in Sentences

• Ensures consistency in lists or comparisons.
• Example (Incorrect): “He likes running, to swim, and biking.”
• Example (Corrected): “He likes running, swimming, and biking.”

7. Sentence Variety and Clarity

• Use a mix of sentence types for better readability.
• Avoid redundancy and unnecessary words.
• Example:
  • “She was very happy and excited.” (Better: “She was thrilled.”)

8. Active vs Passive Voice

• Active: The subject performs the action.
  • Example: “The teacher explained the lesson.”
• Passive: The subject receives the action.

9. Common Sentence Structure Mistakes and How to Avoid Them

• Misplaced Modifiers: Place modifiers near the word they modify.
  • Incorrect: “She almost drove her kids to school every day.”
  • Correct: “She drove her kids to school almost every day.”

10. Conclusion

• Practice different sentence types to enhance variety and coherence.
