Euxine: archaic name for the Black Sea, from Latin Pontus Euxinus, from Greek Pontos Euxenios, literally "the hospitable sea," a euphemism for Pontos Axeinos, "the inhospitable sea."

According to Room, The Old Persian name for the sea was akhshaena, literally "dark," probably in reference to the sudden, dangerous storms that make the sea perilous to sailors and darken its face, and the Greeks took this untranslated as Pontos Axeinos, which was interpeted as the similar-sounding Greek word axenos "inhospitable." Thus the modern English name could reflect the Old Persian one.

Eve: fem. proper name, from Biblical first woman, Late Latin, from Hebrew Hawwah, literally "a living being," from base hawa "he lived" (cf. Arabic hayya, Aramaic hayyin).
Like most of the explanations of names in Genesis, this is probably based on folk etymology or an imaginative playing with sound. ... In the Hebrew here, the phonetic similarity is between hawah, "Eve," and the verbal root hayah, "to live." It has been proposed that Eve's name conceals very different origins, for it sounds suspiciously like the Aramaic word for "serpent." [Robert Alter, "The Five Books of Moses," 2004, commentary on Gen. iii:20]

Modern adverbial sense (introducing an extreme case of something more generally implied) seems to have arisen 16c. from use of the word to emphasize identity ("Who, me?" "Even you," etc.) Sense of "on an equal footing" is from 1630s. Rhyming reduplication phrase even steven is attested from 1866; even break first recorded 1911. Even-tempered from 1875.
