Morrobolam is a Lamalamic (Paman < Pama-Nyungan) language of Cape York Peninsula in north-eastern Australia. Like other languages in the region, it has unusual sound and word structures by Australian standards. This dictionary provides a detailed analysis of the forms, meanings and uses of Morrobolam words, generously illustrated with example sentences from texts. It is of interest to linguists, anthropologists and other scientists, but can also be used as a practical guide to the language, for community members and anyone else with an interest in the region.
