First attested in 1871; back-formation from notation or from Latin notātus, perfect passive participle of notō; either way, see -ate (verb-forming suffix). By surface analysis, note + -ate.
nisus
Origin
From Latin nīsus (“pressure, exertion”).
oblast
Origin
From a Slavic language, probably Russian о́бласть (óblastʹ, “region, province”), borrowed from Old Church Slavonic область (oblastĭ), from Proto-Slavic *obolstь, from earlier *obvolstь, *obvoldtь, a compound of *o(b)- (“over”) + *volstь (“rule, power, authority”), thus originally probably meaning "a region ruled over". Compare Proto-Slavic *obvoldati (“to rule”).
