A "disambiguation phrase" is a phrase that answers a disambiguation question ("which book do you mean...").

A disambiguation question can be answered with several types of syntax:

all/everything/all of them
both/both of them
any/any of them
<disambig list>
the <ordinal list> ones
the former/the latter

Note that we assign non-zero badness to all of the ordinal interpretations, so that we will take an actual vocabulary interpretation instead of an ordinal interpretation whenever possible. For example, if an object's name is actually "the third button," this will give us greater affinity for using "third" as an adjective than as an ordinal in our own list.
