I'm currently studying the "Sentence Structure" for the English language. I've found varied information in this regard.
Some sources says that the sentence consist of five components:
Subject + Predicate + Object + Complement + Modifier
Some other sources say that it consist of only two components:
Subject + Predicate.
Now, I'm confused, whether predicate actually includes the object, complement, and modifier in itself or not. If yes, why some sources mention them separately from the "Predicate"?
