At this website, you can choose from the list on the left for the topic(s) you need to learn about.

I'll give you an example, using this sentence:
Three little old ladies met for tea.

The simple subject is "ladies" but the subject phrase -- also known as the complete subject -- is "Three little old ladies"

The subject is the noun or pronoun that is doing the action.

Examples:

Joe volunteered to help the baseball team.

The most magnificent sight in the world is the Grand Canyon.

A subject phrase is a gerund or infinitive phrase that tells what is doing the action.

Winning eight gold medals was his dream.

The difference between a subject and a subject phrase lies in their grammatical functions.

A subject is a grammatical term that refers to the main noun or pronoun that performs the action or is described in a sentence. It usually answers the question "who" or "what" before the verb. For example, in the sentence "John is eating an apple," the subject is "John" because he is the one performing the action of eating.

On the other hand, a subject phrase is a group of words that includes the subject and any words related to it, such as adjectives or modifiers. It provides more information about the subject. For instance, in the sentence "The tall man with a beard is reading a book," the subject phrase is "The tall man with a beard" since it includes the noun "man" along with the descriptors "tall" and "with a beard."

To identify the subject, you can ask yourself:

- Who or what is performing the action in the sentence?
- Who or what is being described or talked about?

By analyzing the structure and meaning of the sentence, you can determine both the subject and the subject phrase.
