Low tone spreading in Buli
- In Buli, tone indicates lexical information as well as grammatical information. The changing of tone patterns regularly observed on lexemes is covered best by an autosegmental approach with autonomous tonal and segmental tiers. It reveals considerable deviations between underlying and surfacing tones at several morpho- yntactic points. Realization of tone is sometimes oppressed or delayed. Cause for such disturbances is in all cases a low tone which spreads to the right and affects following high tones with different results. The aim of this paper is to show how L spreading acts and how it is integrated in the system of tonal contrast.
