Here’s this but if you still don’t understand and need help just let me know!
A simple subject is a main word or words that tell whom or what a sentence discusses. The simple subject is only who or what is “doing” the verb, without any modifiers. Simple Subject Examples: Thomas Edison invented the light bulb. In this sentence, “Thomas Edison” is “doing” the verb, “invented.”
The simple predicate of a sentence is the verb that is done in the sentence. It can be the action that happens, the state of being, or the linking verb. Hint: Ask yourself, "The subject did what?" It can help if you find the subject first.
For example, "My son and heir will rule this kingdom." In this sentence, "son" and "heir" refer to the same person. Generally speaking, however, compound subjects will be treated as plural and take a plural verb: Dolphins and elephants are highly intelligent creature.
A compound predicate gives two or more details about the same subject and has two or more verbs joined by a conjunction. For example: "She visited her cousins and met all their friends." In this example, "she" is the subject and "visited" and "met" are the predicates joined by the conjunction "and".
