It has been a long time since I learned this in school.
Samson [simple subject] ruled [simple predicate] as an Israelite judge for twenty years.
The simple subject in this case is the proper noun Samson. Simple subjects are usually nouns or pronouns. A noun is a person, place, thing, or an idea. A pronoun is a word that takes the place of one of more nouns. (Here are some pronouns: I, he, she, it, you, we, they). The simple predicate would be the verb, in this case ruled. A verb is a word that shows action or a state of being.
