What is the predict in the sentence The naval aviators were physically abused in horrible ways.

The predict? Or the predicate?

The predicate in any sentence is the main verb and all the words that go with it. You can usually draw a line between the subject and the verb and the predicate will be everything after the line. Where would you draw the line between subject and verb in this sentence?

yes the predicate,, I think the predicate is were abused and the subject is aviators

The simple predicate ( verb) is were abused. The complete predicate is - were physically abused in horrible ways

The complete subject is "the naval aviators"; the simple subject is "aviators".

In the sentence "The naval aviators were physically abused in horrible ways," the word "predict" appears to be irrelevant and does not have a clear connection to the sentence or its meaning. If you have a different question or need assistance with understanding a particular aspect of the sentence, please let me know, and I will be happy to help.
