Simple subject

"Simple subject" is the term used for the single word that is the subject of a verb.

A simple subject will often have modifiers before or after it, but, once these are removed, the word left is the simple subject.

Examples: 


      1. The hungry fox darted across the yard.

    ("The" and "hungry" are modifiers for the simple subject "fox."

    2. The small carton of nails was found under the seat.

    ("The," "small," and "of nails" are modifiers for the simple subject "carton.")
