The adj MORTAL (deadly, doomed to die) derives from the Latin mortalis (subject to death) from mors (death, gen. mortis), which is a transliteration of the Greek μόρος (moros; death) from the verb μείρω (miro; separate, split, divide; as the dead is separated from all the others).
From the same root: mortality, immortality, murder, mortuary
In modern Greek

β) μοιράζω: divide, share (out/in) [mirazo]
γ) μοιραίο: fate, doom, death, fatality [mireo]
