I claim that Bora classifiers have the structural status of (bound) nouns, based on facts like the following:
- Some classifiers also occur as independent nouns (possibly with minor phonological differences).
- Classifiers have the referential properties typical of nouns. Like typical nominals, they denote classes of objects and may refer to a member of the class they denote. They are never used to attribute properties to another referring expresssion.
- Classifiers have the distribution typical of nouns: they may be a clausal subject, they may be modified by a relative clause, they may have a prepositional complement, and so forth.
And classifiers head noun phrases, a claim for which various arguments are given, among them one based on the remarkable similarity between the host-classifier and possessor-possessed constructions.
