Middle English, going back to Old English hring (masculine strong noun), going back to Germanic *hrenga- (whence also Old Frisian hring, ring "ring," Old Saxon hring "chain mail," Old High German ring, rinh "ring," Old Icelandic hringr), going back to dialectal Indo-European *krengho-, *krongho-, whence also Old Church Slavic krǫgŭ "circle, ring," Bosnian-Croatian-Serbian krûg, Polish krąg
Note: The only certain attestations of this etymon are in Germanic and Slavic. As it violates an Indo-European root structure constraint on co-occurrence of a voiceless stop and a voiced aspirate stop, the etymon is presumably late or post-Indo-European, or borrowed from an unknown source.
