I learned that a noun has six functions. One of those funstions are, subject of a verb. Can you provide a definition of, "subject of a verb."

This site will give you an excellent definition and good examples.

Thank-you

Of course! The subject of a verb is a noun or noun phrase that performs the action described by the verb or is being described by the verb. It is the main component of a sentence and typically comes before the verb in the sentence structure. The subject of a verb answers the question "Who or what is doing the action?" or "Who or what is being described?"

For example:
- "John runs every morning." In this sentence, the noun "John" is the subject of the verb "runs." It tells us who is performing the action of running.
- "The cat is sleeping." Here, the noun phrase "The cat" functions as the subject of the verb "is sleeping." It tells us what is being described or what is in a certain state.

To further understand the subject of a verb and see more examples, I recommend visiting the website http://grammar.ccc.commnet.edu/grammar/subjects.htm. It provides a detailed explanation and additional resources on this topic.
