Katupha’s Law

Makhuwa phonology, Mozambique

View in the constellation

Katupha’s Law is the name given to a Makhuwa deaspiration process that restricts the distribution of aspirated consonants within stems. In the analysis presented, multiple aspirates are reduced so that only the final aspirated consonant remains, with the process visible in causative formations and some reduplicated stems. Its regularity varies by dialect and morphological context.

  • What is the link between Katupha’s Law and Dahl’s Law?
  • About Katupha’s Law: can you clarify “A Makhuwa stem is the relevant phonological domain”?

The Story

Katupha’s Law is proposed to account for recurring deaspiration patterns in Makhuwa. The process is defined within the stem, which includes the root together with derivational and inflectional suffixes, rather than merely within adjacent syllables. This domain explains why the addition of a causative extension can alter aspiration in an earlier part of the stem.

Causative formations provide the clearest evidence. Forms such as ottipha ‘to extinguish’ and ottipiha ‘to extinguish transitively’, or othuma ‘to buy’ and otumiha ‘to sell’, show loss of aspiration when the causative extension is added. Comparable alternations occur with verbs meaning ‘to leave’, ‘to frighten’, ‘to produce’, ‘to make arrive’, and ‘to break transitively’, although some dictionary forms preserve competing spellings.

Reduplication reveals both the reach and limits of the process. Some fully reduplicated stems retain more than one aspirated consonant, while other forms such as epwittipwitthi and nipattapattha show deaspiration. The analysis therefore treats Katupha’s Law as applying to all but the last aspirated consonant, while allowing that full reduplication, dialect differences, and non-adjacent consonants may weaken its enforcement.

Key Points

  • A Makhuwa stem is the relevant phonological domain
  • Causative formation triggers systematic deaspiration
  • Reduplication shows variable application
  • The final aspirated consonant is preserved
