On the Representation of NC Clusters in Bemba
Nancy Chongo Kula
1. Introduction
In this paper I aim to provide an analysis of Nasal Consonant clusters. In attempting
to derive the facts of nasal place assimilation two views of Nasal Consonant
clusters (NC's henceforth) have evolved, namely; as a unit segment, complex
segment or nasal contour, on the one hand, and as sequences of segments on the
other. To account for NC's as attested in Bemba, I propose an analysis of NC
clusters, in the framework of Government Phonology (GP) (Kaye, Lowenstamm
and Vergnaud, 1985, 1990) as sequences of consonants employing onset to onset
government and licensing constraints. The structure of this paper is as follows:
Section 2 presents the phonological behaviour of NC's in Bemba, Section 3 gives
some proposals that have been made for the representation of NC's, in Section 4 I
give a brief background of Government Phonology, followed by my analysis and
proposal's and Section 5 offers some concluding remarks.
2. Phonological behaviour of NC's in Bemba
The only consonant clusters found in Bemba,
1
as in many other Bantu languages,
either involve 'semi-vowels', or a nasal and a homorganic consonant.

In order to
motivate the structure I propose for NC's in Bemba, I present four relevant
environments; assimilation, strengthening of consonants, NC simplification, and
nasal consonant harmony (2.1-2.4).
2.1 Homorganicity
In Bemba the nasal in NC's is homorganic to the following consonant. This follows
from the notion that nasals are typically placeless consonants that need to share a
place of articulation with a following consonant as long as it is available. This can
be seen with the 1st person singular prefix n- when followed by different stem-
initial consonants:
