(Strong's #2176 — Adjective — euonumos — yoo-o'-noo-mos )

lit., "of good name," or "omen" (eu, "well," onoma, "a name"), a word adopted to avoid the ill-omen attaching to the "left" (omens from the "left" being unlucky, but a good name being desired for them, cp. aristeros, lit., "better of two," euphemistic for the ill-omened laios and skaios; cp., too, the Eng., "sinister," from the Latin word meaning "left"), is used euphemistically for No. 1, either (a) simply as an adjective in Revelation 10:2 , of the "left" foot; in Acts 21:3 , "on the left" (lit., "left"); or (b) with the preposition ex (for ek), signifying "on the left hand," Matthew 20:21,23; 25:33,41; 27:38; Mark 10:40 (for ver. 37, in some mss., see No. 1); 15:27.
