The context-set prose is insufficiently explicit.  What we're
describing here is the _former_ case, a list of words -- it's just
that you're interested in the special case where the list has only a
single element.  In other words, the dichotomy is not between single
and multiple words, it's between words (any number of them) and other
things (such as integers).

Yup, that's the way to go for now.

No offence, you have merely been misled :-)

Me, too.
