Rule for subject verb agreement. My grammar book states that " If two subjects are joined by and then the verb comes in plural form" for instance" John and Matt are coming." But in another sentence I read " He and not his parents is plead guilty to obscenity charge." here the verb agrees with the subject former to 'and'. Is this an exception?
He and not his parents is plead guilty to obscenity charge is not grammatical; maybe it should be is to plead or has plead. Whatever the case, it should be obvious that there is a singular subject (he) that takes a singular verb. The sentence itself rules out another subject by saying and not - - - -. Therefore doesn't it make sense that the verb should be singular? The first sentence could be John and not Matt is coming. Note that John is the only one coming so the verb is singular.
