As a matter of fact, Jens Rasmussen speculates that *-esto- itself is
analogical as well, and that the original adjectival derivatives of
es-stem nouns ended in *-eto- (parallelling *s ~ *t alternations found
elsewhere). Cf. Skt. namas- 'homage' vs. Gaul. nemeton 'holy place'
(*nem-es-, adj. nem-et-o-). If so, an older PIE *wenh1-et-o- was
replaced by "dialectal" *wenh1-es-to- (because of *wenh1-es-), and of
course in the immediate ancestor of Latin *wenesto- was influenced by
the vocalism of *wenos, yielding *wenosto-.
