I take it that we are kind of stuck with it for the grammatical category as it is built into RDF syntax as rdf:Predicate. I think that as long as we use it along with 'subject' and 'object' only as a kind of syntax-technical term for the middle part of a triple, and take care not to say that the things in the domain - the things denoted - *are* predicates, this will be fine. After all, we can say that John is the subject of the sentence 'John loves Mary', but it would seem odd to categorize him as being a subject rather than a human being on that basis.
