Tone assignment and grammatical tone in Anal (Tibeto-Burman)

Pavel Ozerov

Abstract

Complex phenomena of grammatical tone, well-described for many African languages, are increasingly attested also in the Tibeto-Burman family. This paper describes the tone assignment rule and two cases of tonal expression of grammatical categories in the Tibeto-Burman language Anal. The typologically unusual rule involves tone spreading, tonal polarity on a non-edge constituent and additional spreading, resulting in constant tonal patterns across grammatical suffixes. In two different cases the combination of the tonal pattern assigned by this rule with peculiar morpho-tonological processes results in a marking of a grammatical category (future and 1sg-person) by grammatical tone, by vowel-length, or only by the overall tonal pattern of the verbal form. Both cases are related to the omission of an explicit marking of the category, although the outcome cannot be explained only by the concept of a floating tone.
