||Chung, Chin-Wan. (2020). An aspect of NC cluster realizations in Bukusu. The Linguistic Association of Korea Journal, 28(4), 121-145. This study observes various realizations of a nasal plus a consonant (NC) sequence in Bukusu. The newly created Bukusu NCs are composed of a prefix nasal plus a stem-initial consonant, and they are required to have the identical laryngeal, continuant, and place features. If any NCs do not meet these requirements, several sound modifications occur to render NC harmonious with the NC structural requirements. If a post-nasal consonant is a voiceless obstruent, progressive voicing assimilation occurs and then a post-nasal consonant triggers regressive place assimilation. Hardening occurs when a post-nasal consonant has [+voice, +cont]. Post-nasal /l, r, β/ optionally merge with the preceding nasal after becoming hardened and triggering regressive place assimilation if they are followed by a nasal or an NC-initial syllable in a stem. A nasal prefix is deleted if a stem begins with a nasal or a voiceless-initial fricative. Even though different sound change strategies are used in Bukusu, their goal is to make an NC satisfy the requirements of the cluster. In order to provide an analysis, we adopt a constraint-based theoretical framework which allows steps before reaching the final optimal form. This is because some of the sound modifications should occur sequentially. The constraints and their rankings used in the analysis can capture the functional unity that is hidden in sound modification strategies.
