||Do we need to postulate a different tone pattern for monosyllabic verbs in Nyoro?

Nyoro, a Bantu language of western Uganda, has two tone patterns for nouns; tone pattern A in which an underlying H is placed on the ultimate syllable of words, and tone pattern B in which an underlying H is placed on the penultimate syllable of words. All verb infinitives (or gerunds) have tone pattern B except monosyllabic verbs, which curiously have tone pattern A. The aim of this paper is to determine the reason monosyllabic verbs have tone pattern A and all the other longer verbs, including monosyllabic verbs themselves extended by other elements, exhibit tone pattern B. It was concluded that the formative -ku-(class 15 nominal prefix), which is used as a tense/aspect/mood marker including the infinitive, is incapable of having an underlying H even when it is in the penultimate syllable;rather, the ultimate syllable receives the underlying H, thus exhibiting tone pattern A.However, there is one counter example which seems to indicate that the formative -ku-,starting from its use as a verb infinitive marker, has partially become a true tense/aspect/mood marker, and can have an underlying H similar to other tense/aspect/mood markers, such as -ka- in the remote past, which has an underlying H even in the penultimate syllable conjugated with monosyllabic verbs.
