Tone is well-known for playing a role in the makeup of inflection, but the literature has not yet produced a comprehensive typology of the relation between tone and inflection from a morphological perspective. There are various reasons for this. On the one hand, the interest in the morphological side (i.e. the form) of inflection has lain outside the general spotlight of linguistic typology, which, except for the Surrey Morphology Group, has been mainly concerned with trying to make sense of linguistic structure in functional terms. I show here that in most situations where tone is involved in inflection it is difficult, if not impossible, to give it a clear-cut morphosyntactic function.
