Here's why:
* Subject: The subject is the person, place, or thing that performs the action of the verb. It's the main topic of the sentence.
* Conjunction: A conjunction connects words, phrases, or clauses. It doesn't have its own meaning or action.
Example:
* The cat (subject) and the dog (subject) played (verb).
Here, "and" is the conjunction connecting the two subjects, "the cat" and "the dog".
