deasil (adj.)

"right-hand-wise, turned toward the right; clockwise," 1771, from Gaelic deiseil, deiseal (adjective and adverb) "toward the south," taken in sense of "toward the right," from deas "right, right-hand; south," cognate with Irish deas, Old Irish dess, des, Welsh dehau, and ultimately with Latin dexter, from PIE root *deks- "right; south." The second element of the Gaelic word is not explained (one old guess, in the Century Dictionary, is a proposed *iul "direction, guidance").
