Notes:One wonders whether this root may have been derived from Afras. *ʔar- 'elephant/hippopotamus' (3628), with the -b formant (of harmful animals?). Cf. Blaz. Eleph. 198, 203. In CCh (Kotoko group) *-f versus *-b in other Afrasian is difficult to explain. Cf. ECush: Oromo rōbī, rōṗī; Burji rōbḗ; Sidamo robē, robicco, Darasa rōṗe reconstructed by Blazek as *robH- 'hippopotamus' (Bla. Eleph., 203; add also Geleba rooṗe id. Huds. HEC, 80), likely related with the present root. Blazek also includes in *robH- two forms which are probably related to *lVʔVb- ~ *ʔVlb- 'elephant/hippopotamus' (131).
Notes:Cf. Tak. 94,136: comp. Eg. ʕr 'goat' with SCu (<*ʔ-, not ʕ-, which Takac himself sygnalizes) and Dah ēri (mistake: should be hééri - in Ehr., and EhrEldNurse 15). The Chad. forms compared with Eg. ʕr 'she-goat' ([Tak. ibid.]; accepted by [Tak I 136-7]) are reconstructed with *ʕ-. This contradicts the correspondences proposed by Stolbova: for the Sura group, to which Mnt. and Grk. belong [Stolb. 1996 7], Afras. and P. Chad *ʔ- and *ʕ- yield *ʔ- [ibid. 74, table 7], while in the Lai group, to which Lele belongs [ibid. 8], the situation with laryngeals is obscure [ibid. 74, table 7; 97, table 19]. Cf. HSED 50: Can.; Boni eriya, Rnd. ari (both not found in dict. available), Burji; SCu. Bl.Beja Fauna 22: Cu. Cf. Dolg. HSAn.names 2 (Sem, Beja), 4 (to Sem-Eg *ʕyr 'ass': Dah heri 'goat, sheep'; SCu ara 'goats'; WCh ur 'he-goat', Lele ōrē 'goats')
