The Punan Sajau language according to Jerome Rousseau (1990) is closely related to us the Punan (Punan Ba) in Sarawak. However we can tell that’s not entirely true although there are few words sound familiar, but one in particular sound like Punan – “unan” – which mean with in Punan language. Not sure if it has similar meaning in Punan Sajau language.
The rest rest sound more like a Indonesian / Kenyah? / Penan words?
