Word Origin & History

helix
1563, from L. helix "spiral," from Gk. helix (gen. helikos), related to eilein "to turn, twist, roll," from PIE base *wel- "to turn, revolve" (see vulva).

Corinthian
1650s as an architectural order, from Corinth, the ancient Gk. city-state. In classical times Corinth was notorious for its luxury and licentiousness among the Greek states (and for not scorning trade and profit); hence Corinthian n. and adj. in various slang or colloquial
sense in English, especially "a swell, a man about town" (early to mid-19c. but especially in the 1820s).
