Types of English Speech in Grammar
English grammar classifies words into parts of speech, each serving a unique function in sentences. Below are the main types, their forms, uses, and exceptions.  
1. Nouns
- Forms: Proper (London), Common (city), Abstract (love), Collective (team), Countable (book), Uncountable (water).  
- Use: Names people, places, things, or ideas.  
  - Example: "The dog barked loudly."  
- Exceptions: Some nouns are both countable and uncountable (e.g., "hair" vs. "hairs").  
2. Pronouns
- Forms: Personal (I, you), Possessive (mine, yours), Reflexive (myself), Relative (who, which),  Demonstrative (this, that).  
- Use: Replaces nouns to avoid repetition.  
  - Example: "She gave me a gift."  
- Exceptions: "They" can be singular in modern usage (e.g., "Someone left **their** bag.").  
3. Verbs
- Forms: Action (run), Linking (is), Auxiliary (have, will), Modal (can, must).  
- Use: Expresses actions or states.  
  - Example: "He runs every morning."  
- Exceptions: Irregular verbs (go →went →gone) don’t follow standard conjugation.  
4. Adjectives

- Use: Modifies nouns.
