I wonder, too. Since the Greenberg method uses a continuous scale (or
set of continuous scales), it isn't possible to find a principled
point at which a language is no longer merely "synthetic" but has
attained the status of "polysynthetic". Greenberg suggests that a
language scoring 3.00 or above on the synthesis index (average number
of morphs per word) be called "polysynthetic". But a language with a
score of 3.00 or above could very well be missing some of the
morphosyntactic features that are usually associated with
polysynthesis such as head-marking morphology, object incorporation,
an open class of bound morphemes, object and subject agreement, etc.
As for word boundaries, speakers of a language are generally in
agreement as to what constitutes a "word" of their language. If a
Greenbergian typological examination is being done using texts that
have been "vetted" by native speakers, then I think the results can be
relied upon.
