arachrin

Old Irish

Originally a euphemism or slang expression meaning “shake it”, from Proto-Celtic *ɸarekriniti (compare Welsh ergryn (“tremble, fear”)) with the infixed pronoun a- (“it”), from *ɸare- (“in front”) +‎ *kriniti (“to shake, sift”), from Proto-Indo-European *krinéh₁ti (“to shake, sift”), from Proto-Indo-European *kreh₁(y)-. Cognate with Welsh crynu (“to shake, shiver”), Latin cernō (“to sift, separate”), and Ancient Greek κρῑ́νω (krī́nō, “to separate”).^[1]
