KJV, Eurus the Greek god and Euroclydon

If using the term is problematic, then the problem lies with Luke, since he calls it Ευροκλύδων (or in some manuscripts Ευρακύλων), i.e., Euroclydon, or the Northeaster, from Greek ευρος, east wind, and Latin aquilo, north wind.

 

Acts 27:14

And not aftir miche, the wynde Tifonyk, that is clepid north eest, was ayens it.
(John Wycliffe Bible 1185)


But anone after ther arose agaynste their purpose a flawe of wynde out of the northeeste.
(Tyndale Bible 1534)

 

The texts used by the KJV, and WEB use a variant reading. But if you just transliterate the Greek, you get "eurakylon." Why not just use that for the name of a wind that produces dangerous waves? That is what Luke wrote, why not stick with it. If you want to footnote it, say the name may refer to an east-northeast wind, but sources are not in good agreement.

 

Etymology usually (not always) has little to do with the meaning of the word. Modern linguists (including the lexicographers who edit our English dictionaries) look for the contemporary usage of a word--its meaning as used by the people of the day.

The neighborhood of our church here in Japan is called Kyokushin (旭神), which by the Chinese characters ought to mean "The morning sun of a god." In reality, though, the Chinese characters were chosen not for their meaning but for the pronunciation of an Ainu word, not Japanese at all.

Likewise, the 1st century Greeks probably didn't think about the Greek god Eurus when they used the word, but the actual winds. So, personally I see no problem with the use of the word in the translations mentioned.
