    As good as the peccadillo sentence is, it is not on a par with the postilion sentence. Nothing is. That sentence is cast in golden moonshine and should never be disturbed.

    To test whether a candidate sentence is a postilion sentence, all we have to do is try to identify the context(s) in which it would be used. If we have difficulty finding a plausible context, then we have such a sentence.
