Morphology in Austroasiatic Languages

Abstract

The languages of the Austroasiatic (AA) language family share a core set of derivational prefixes and infixes that are largely fossilized. Beyond these, there is a wide range of morphological features throughout these more than 160 languages. Of the 13 branches of AA, there is a geographically central concentration of branches with predominantly isolating morphology (Khmeric, Monic, Vietic, and Pearic), while geographically peripheral branches have more complex morphology (Aslian and Khasic), and some with inflectional morphology (Munda and Nicobaric). Other branches are typologically between, largely lacking inflectional morphology (i.e., systematic, productive grammatical morphology) but having a somewhat more complex range of morphological features (Katuic, Bahnaric, Palaungic, Khmuic, and Mangic), including those with some grammatical functions. Other than Munda and Nicobaric, most AA languages have iambic word-level stress and have only prefixes and infixes while lacking suffixes. This has resulted in a collapsing of older morphological material, while new affixes, with new morphosemantic functions, emerge. Alternating reduplication, in which complete prosodic templates are copied but various segments are alternated, is a common word-formation strategy and sometimes combines with prefixes and affixes. While lexical compounds are common, so are pseudo-compounds with near affix-like semantic, and sometimes phonological, features. Overall, while monomorphemic words are common among the more isolating types of AA languages, ample linguistic descriptions show a substantially wider range of morphological complexity throughout the AA language family.
