I'm bikeshedding this in the other direction, because I think that the length / verbosity of the messages is an important factor, so we shouldn't insert meaningless words just to simplify the code. We do not need absolutely perfect grammar, if we're attaching an article to an arbitrary variable name, it's OK if there are rare situations when it doesn't fit the pronunciation.
