Lamalamic root structure: Erosion and expansion

This study analyses the structure of lexical roots in the Lamalamic languages of Cape York Peninsula, in the northeast of Australia. The analysis shows how Lamalamic roots are shaped diachronically by processes of erosion and expansion, leading to root forms that are unusual by Australian standards. Erosion processes include the loss of initial consonants, resulting in vowel-initial roots, and the loss of entire initial syllables, resulting in monosyllabic roots. Expansion processes include leftward expansion through the addition of meaningless VC prefixes, and rightward expansion through morphological augmentation and subsequent semantic bleaching. The analysis describes the basic processes involved for the languages, using historical-comparative and phonotactic evidence, and brings out two points of more general relevance. First, the analysis proposes an analogy-based mechanism to explain loss of initial vowels, which complements the classic account in terms of gradual initial weakening. Second, the analysis also suggests that erosion and expansion processes may be functionally related, in that there is some evidence that expansion processes could originate in a mechanism to counterbalance the development of monosyllables.
