Note that toneless forms include an additional candidate which satisfies the constraints proposed here, yet needs to be eliminated.
Recall that the lexical level is characterised by a bifurcation into forms that are toneless and those that possess tone.
The tonal processes captured in this section fully preserve the bifurcation of forms into toneless and those endowed with tone.
The assumption that non-high-toned syllables are toneless, on the other hand, accounts for all these facts without requiring any more assumptions.
It was argued that features from the surrounding environment spread to underlyingly toneless syllables and featureless vowels.
We begin with lexically toneless forms.
The problem is how to decide and ensure that in one context a floating tone/toneless mora results phonetically in a modified level tone and in another context a contour.
Toneless monosyllabic, and monomoraic, nominal bases exhibit the behaviour typically associated with minimal word requirements.
