Subject Forms
The most common grammatical forms of subjects in English are nouns (e.g. car, dog, book) and pronouns (e.g. he, she, it)
Examples of this are:
1. We (personal pronoun) love that song.
2. Who (interrogative) is on the phone?
3. Shohei Ohtani (proper noun) is a very famous baseball player.
However at times larger forms are also used.
- Gerunds (e.g. swimming, reading, running)
- Infinitives (e.g. to swim, to read, to run)
- Noun phrases (e.g. the big red car, my best friend
Simple and Complete Subjects
The simple subject is the main word in the subject of a sentence and usually refers to the person or thing performing the action of the verb. The complete subject, on the other hand, includes the simple subject along with any modifiers or other words that describe or identify it.
For example, in the sentence "The cat sat on the mat", "cat" is the simple subject and "The cat" is the complete subject.
In summary, the simple subject is just the main noun or pronoun in the subject of a sentence, while the complete subject includes the simple subject along with any accompanying words.
Compound Subject
Compound subjects are subjects that consist of two or more nouns or pronouns joined together by a conjunction, such as "and," "or," or "nor." These subjects share the same verb in a sentence. For example, in the sentence "Sara and John are going to the beach," the compound subject is "Sara and John."
