Etymology

Inherited from Middle English rocke, rokke (“rock formation”), from Old English *rocc (“rock”), as in Old English stānrocc (“high stone rock, peak, obelisk”), and also later from Anglo-Norman roque, (compare Modern French roc, roche, rocher), from Medieval Latin rocca (attested 767), of uncertain origin, sometimes said to be of Celtic (in particular, perhaps Gaulish) origin (compare Breton roc'h). Related also to Middle Low German rocke (“rock ledge”). One suggestion is that it derives from Vulgar Latin *rupica, from rupes (compare rupico).
