ἄμετρος <Egyptian; Roman period>
👉 ἄμετρος – an Egyptian gloss with the meaning of βάτος ‘bramble (Rubus ulmifolius Schott)’ (Dsc. 4.37 RV).
⚠ Dsc. 4.37 RV: βάτος· (...) Αἰγύπτιοι αἰμοίως, οἱ δὲ ἄμετρος. – “Batos (bramble): the Egyptians (call it) aimoiōs or ametros”. Cf. αἰμοίως.
🅔 An Egyptian word without etymology. The Egyptian word might be distorted under the influence of the adjective ἄμετρος, -ον ‘without or beyond measure, immense’. There are two unacceptable hypotheses: 1. from the Egyptian ꜥmꜥꜥ prob. ‘grain’; 2. ἄμετρος treated not as an Egyptian, but a Balkan gloss (allegedly related to the Albanian mjedër ‘raspberry’).
