Etymology 1
From ~. Cognate with 🇨🇬 Bi, 🇨🇬 [Rục] pəsat⁷. Also compare 🇨🇬 (from earlier *s- through regular debuccalization in Mang), 🇨🇬 [Souei] pəsat ("to extinguish").

Unlikely to be related to, , , unless there was an infix (which is otherwise unknown within Austroasiatic) or metathesis of a presyllable. The first scenario can almost be safely disregarded, but the second is slightly more plausible since this root is attested both on its own and accompanied by presyllables and/or prefixes across Austroasiatic branches, plus the existence of the Souei cognate above. Still, it might just be coincidental.
