A sentence is made of two parts:[complete] subject and [complete] predicate.
I would like to confirm that sentence modifiers are part of the predicate?
What confused me was that sentence modifiers do not modify any specific word in the sentence but rather the whole sentence. This means that they do not modify the subject which is already a noun/pronoun-adverbs do not modify nouns or pronouns. So what is left is that they are part of the predicate.
For example, in the following compound sentence:
I am hungry now; however, I cannot eat.
The transitional word however is a sentence modifier and is part of the second simple sentence.
Sentence modifiers include sentence adverbs and absolute phrases.
