While there is no doubt that the MSA designations of “sea” go back to a single prototype, its exact shape is hard to recover because of deep structural changes in individual languages. Nevertheless, it is tempting to suppose that the Proto-MSA form was close to Eastern Jibbali rέmrɛm, with full reduplication of the biconsonantal element *rVm- (cf. already Bittner 1909:128, 1914:55). The origin of this form is with all probability descriptive (onomatopoetic), but no exact parallel seems to be attested in the Semitic-speaking domain (although, as far as verbal roots are concerned, cf. Akk. ramāmu ‘to rumble, to roar, to howl, to bellow,’ CAD R 116, AHw. 949, Tna. ramram bälä ‘to be an indistinguishable, incomprehensible noise,’ TED 547). (Kogan 2015:569)
