What Are Parts of Speech?
Parts of speech are categories of words based on their function in a sentence. Every word in English belongs to at least one part of speech depending on how it is used.
The traditional classification includes eight main parts of speech:
- Noun
- Pronoun
- Verb
- Adjective
- Adverb
- Preposition
- Conjunction
- Interjection
Some modern grammarians also include Determiners as a separate category.
1. Noun
Definition:
A noun is a word that names a person, place, thing, or idea.
Examples:
- Person: teacher, doctor, Riya
- Place: Delhi, school, park
- Thing: book, car, phone
- Idea: freedom, happiness, honesty
Example Sentences:
- The teacher explained the lesson.
- Freedom is important for everyone.
- The car is parked outside.
Types of Nouns:
- Proper Noun (India, John)

Common Mistake:
Confusing common and proper nouns.

2. Pronoun
Definition:
A pronoun replaces a noun to avoid repetition.
Examples:
I, you, he, she, it, we, they, him, her, them

- Reflexive (myself, himself)
- Demonstrative (this, that)

Common Mistake:
Using subject pronoun instead of object pronoun.
