The story you may have heardThe extracted draft ran Tamil akil to Hebrew ʾăhāl to Greek aloē, which makes aloe a Hebrew word. Hebrew ʾăhālîm (Num 24:6, Ps 45:9) is fragrant eaglewood, probably from Tamil akil. The Septuagint and Vulgate rendered it with the Greek and Latin word for an unrelated plant, likely because the two sounded alike (OED, via Etymonline). Hebrew gave aloe a second meaning, not its form. The Greek word's own source is still unknown.
