Comments: JLTT 780. Accent reconstruction is not quite clear: for *usinap- 'to lose' the pattern *HHH is more or less secure, but for *usa- it seems best to reconstruct *ùsá- (indicated by Tokyo and Kyoto). We may actually be dealing with two original roots heavily interacting with each other. japet-prnum,japet-meaning,japet-rusmean,japet-ajp,japet-mjp,japet-tok,japet-kyo,japet-kag,japet-comments,
