Subject Nouns:
* What they are: Subject nouns are the words that perform the action of the verb in a sentence. They are the "who" or "what" doing something.
* Examples:
* The cat chased the mouse. (Cat is the subject noun, doing the chasing)
* John wrote a letter. (John is the subject noun, doing the writing)
* The sun shines brightly. (Sun is the subject noun, doing the shining)
Subject Pronouns:
* What they are: Subject pronouns are words that replace subject nouns to avoid repetition. They still perform the action of the verb.
* Examples:
* He chased the mouse. (He replaces the subject noun "cat")
* She wrote a letter. (She replaces the subject noun "John")
* It shines brightly. (It replaces the subject noun "sun")
Key Differences:
1. Word Type: Subject nouns are regular nouns, while subject pronouns are a specific type of pronoun used in the subject position.
2. Replacement: Subject pronouns are used to replace subject nouns, while subject nouns stand on their own.
3. Examples: The examples above clearly illustrate the difference.
Common Subject Pronouns:
* I
* You
* He
* She
* It
* We
* They
Remember: The subject pronoun always needs to agree in number (singular or plural) with the subject noun it replaces.
