Murrinhpatha word structure is highly complex, and quite distinct from the better-known Pama-Nyungan languages of central and southern Australia. Murrinhpatha is characterised by prolific compounding, clitic clusters, cumulative inflection, irregular allomorphy and phonological assimilation. This book provides a comprehensive account of these phenomena, giving particular attention to questions of morphological constituency, lexical storage, and whether there is really such thing as a ‘word’ unit.
