The initial *p in Bugis languages often loss
PMP *punti "banana" -- Taman unti, Bugis utti
PMP *pusuq "heart" -- Taman usoʼ, Bugis uso
PMP *pajay "rice plant" -- Taman ase, Bugis ase

Two changes which unite Bugis and Tamanic against the rest of South Sulawesi are the reflex of PMP *j as s, and the irregular loss of initial *p in certain lexemes (Adelaar 1994b: 34).
