I might not be right here, but synthetic and analytic aren't particularly different sides of a spectrum. Analytic means very few grammatical constructs are used in a word, nothing to do with morphemes. You can technically be analytic and synthetic. And you can be fusional/agglutanative and polysynthetic. Although you did say that last part.<br>There are three variables to typology; How much you are combining, what you are combining, and how you are combining it.
