Spelling of /uj/

The Brunei Malay dictionary (DBP 2007) lists words such as /paluj/ ‘stupid’ as paloi ‘stupid’, but it then shows the pronunciation as /palui/.

In most entries in the dictionary, the pronunciation is not given, as it is predictable from the spelling and showing the pronunciation would therefore be redundant. On this basis, it is not clear why the spelling is not listed as palui.

In fact, in addition to paloi, the dictionary offers both spelling and pronunciation for the following words. (Here, the orthographic version is shown first, to reflect the entry in the dictionary.)

sikoi/sikuj/ 'melon'
langoi/laŋuj/'look up'
laboi/labuj/'float about' (usually laboi-laboi)
tampoi/tampuj/'a kind of tree' (Baccaurea)
sumboi-sumboi/sumbuj-sumbuj/'pitcher plant' (Nepenthes)
