I cannot see that it is possible to have anything recognisable as language
that is not reducible (or morphable, or pick-your-verb-able) to some kind
of tree. The universe of perception is things happening to objects,
relationships between objects, and relationships between events. That's
pretty irremovable from a tree-able structure, isn't it?
