Khoekhoegowab tone sandhi: New experimental evidence

Abstract

Khoekhoegowab has a tone sandhi process that replaces each underlying tonal melody with an arbitrary secondary melody. This process at first appears to be an unusual example of a "left-dominant" sandhi process in the sense of Yue-Hashimoto (1987) or Zhang (2007). Within a given domain, the leftmost word retains its base from, but the other words undergo paradigmatic substitution; left-dominant systems typically involve spreading of a tonal melody rather than substitution. However, this description of Khoekhoegowab sandhi seems to break down when we consider verbs. Prior descriptions disagree as to whether verb sandhi depends on the placement of a tense-marking clitic (Haacke 1999) or the embedding status of the clause (Brugman 2009). This paper presents the results of a new prosodic production experiment aimed at resolving this conflict. The result is a hybrid generalization: verbs in matrix clauses undergo sandhi when preceded by a tense marker, but verbs in embedded clauses resist sandhi across the board. Thus, Khoekhoegowab continues to look like an exceptional left-dominant system: The verb and tense marking form a sandhi domain in matrix clauses (triggering sandhi on the verb whenever it is not leftmost within that domain), but in embedded clauses verbs form their own independent domain instead.
