1. What Is the Subject?
Definition:
The subject of a sentence is the word or group of words that tells who or what performs the action or who or what the sentence is about.
Basic Examples
The sun rises in the east.
Rahim is reading a book.
Honesty is the best policy.
Bangladesh is the greatest country. [my personal opinion]
In each sentence, the subject answers one simple question:Who or what + verb?
2. How to Find the Subject (Step-by-Step Method)
Step 1: Find the Verb
The verb shows action or state of being.
Example: The little boy is playing in the yard.
Verb: is playing
Step 2: Ask a Question
Ask: Who is playing?
Answer: the little boy
So, the little boy is the subject.
3. Simple Subject and Complete Subject
3.1 Simple Subject
The simple subject is the main noun or pronoun without modifiers.
Example: The tall, intelligent girl won the prize.
Simple subject: girl
3.2 Complete Subject
The complete subject includes the noun and all words describing it.
Example: The tall, intelligent girl won the prize.
Complete subject: The tall, intelligent girl
4. Subject in Different Sentence Types
4.1 Declarative Sentences (Statements)
These sentences state facts or opinions.
Example: Water boils at 100°C.
Subject: Water
4.2 Interrogative Sentences (Questions)
In questions, the subject often comes after the verb or auxiliary verb.
Example: Are you ready?
Rearranged: You are ready.
Subject: you
4.3 Imperative Sentences (Commands)
Imperative sentences usually have a hidden subject.
Example: Close the door.
Hidden subject: You
(You) close the door.
(you) edit the wiki.
4.4 Exclamatory Sentences
These express strong emotion.
Example: What a beautiful day it is!
Subject: it
5. Compound Subjects
A compound subject has two or more subjects joined by conjunctions such as and, or.
Examples:
Rahim and Karim are best friends.
Books and knowledge are closely related.
Each noun/pronoun is part of the subject.
6. Subject Complements (Not Subjects!)
Sometimes learners confuse subjects with words that follow linking verbs.
Example:
Rahim is a doctor.
Subject: Rahim
Subject complement: a doctor
Rule: The subject usually comes before the verb in statements.

8.2 “There” as Dummy Subject
There is a problem. There are many students in the class.
