2. Pronouns and Antecedents
A pronoun replaces a noun to avoid repetition. Its antecedent is the noun it refers to. Pronouns must agree with their antecedents in number, gender, and person.
2.1 Types of Pronouns
| Type | Examples | Usage |
|---|---|---|
| Personal | I, you, he, she, it, we, they | Refer to specific people or things |
| Possessive | my, your, his, her, its, our, their | Show ownership |
| Reflexive | myself, yourself, himself, themselves | Refer back to the subject |
| Relative | who, whom, whose, which, that | Introduce dependent clauses |
| Demonstrative | this, that, these, those | Point to specific things |
| Indefinite | anyone, somebody, everyone, nothing | Refer to non-specific people or things |
2.2 Pronoun-Antecedent Agreement
Number Agreement:
Each student must bring his or her book.
Students must bring their books. (preferred for gender neutrality)
Clear Antecedents:

- Misplaced modifiers: Place adverbs close to the words they modify

5. Articles
Articles are determiners that precede nouns. English has two types: definite (the) and indefinite (a, an).
5.1 Definite Article: "The"
Use "the" when referring to:
- Specific or previously mentioned items: "I saw a dog. The dog was brown."
- Unique objects: "the sun," "the President"
- Superlatives: "the best," "the tallest"
- Musical instruments in general: "play the piano"
5.2 Indefinite Articles: "A" and "An"
Use "a" before consonant sounds; use "an" before vowel sounds:
an hour (silent h)
a European country (sounds like "yoo")
an honest person (silent h)
5.3 When to Omit Articles
No article is used with:
- Plural or uncountable nouns in general statements: "Dogs are loyal." "Water is essential."
- Most proper nouns: "Paris," "Mount Everest"
- Languages: "She speaks Spanish."
- Meals in general: "We ate breakfast."
- Abstract concepts: "Love conquers all."
Life is beautiful. (general statement)
I study the mathematics.

Conclusion
Mastering these parts of speech requires understanding their functions and the relationships between them. Nouns and pronouns must agree in number and gender; adjectives and adverbs must be properly formed and placed; and articles must be used according to whether the noun is specific or general, countable or uncountable. Regular practice and attention to these rules will lead to clear, grammatically correct writing and speaking.
