McF-NP#185	pound rice	1-0-03	4
The problem of accent placement is forefront here. Although only one etymon is reconstructable for PAN (because accent was not differentiated at that level), two can be differentiated for PPH: *báyu and *bayúh. While there may be some justification for a split between PNP *báyu and a PSP *bayúh, some northern and southern  languages justify either accent pattern. It may have to do with an <accent pair>: *báyu was the verb 'to pound rice' and *bayú was the noun 'pestle' (a vessel used for pounding rice). Note that only Cebuano has a doublet.
