Here's a breakdown:
* Noun: A word that names a person, place, thing, or idea (e.g., dog, school, happiness).
* Pronoun: A word that replaces a noun (e.g., he, she, it, they).
* Action verb: A verb that describes an action (e.g., run, jump, eat, write).
* Descriptive verb: A verb that describes a state of being or condition (e.g., is, are, was, were).
Examples:
* The cat chased the mouse. (The simple subject is "cat" because it is the noun that performs the action of chasing).
* She is happy. (The simple subject is "she" because it is the pronoun that is described by the verb "is").
* The flowers are blooming. (The simple subject is "flowers" because it is the noun that is described by the verb "are blooming").
Key Points:
* The simple subject may be a single word or a group of words.
* It may be combined with adjectives or other modifiers, but the core noun or pronoun is the simple subject.
* The simple subject is always located before the verb in a sentence.
Identifying the simple subject can be helpful for understanding the structure and meaning of a sentence.
