Luhu is an extinct Austronesian language spoken in the west of Seram Island in eastern Indonesia. It was spoken in Luhu village on Hoamoal Peninsula at the western end of Seram, and in Boano and Kelang islands, off the western tip of Seram Island.[1]
The northernmost dialect, Piru, was separated from the rest of the language through colonial depopulation, and was influenced by neighboring languages as it became moribund. In 1989, there were an estimated 3,500 native speakers, but by 2024, the language had gone extinct.[2]
