As a literal “May” is a string, and the meaning will depend on the context, e.g. it could be a month, a verb, someone’s family name and so forth.  A common case is where there are somethings that are only true in this particular context whilst other things are true generally.  Contexts are also useful when dealing with departures from the open world assumption.
