From Proto-Afroasiatic, cognate with Arabicأَمَرَة(ʔamara, “heap of stones, mound, esp. as a way-marker”), Akkadian𒀯(amartu, “dividing wall”), 𒋞(amaru, “pile of bricks”), Hebrewאָמִיר(ʾāmīr, “treetop, mountain summit”).

Behold, they were in woe to the height of the sky, as their thick crowd was collected upon the place of their slaughter, and they were made into corpse-heaps on their soil by the might of the king, valiant in his limbs, the only lord, powerful like Montu, Dual King Usermaatre-Meryamun, Son of Ra Ramesses, Ruler of Heliopolis.
Possibly from a Proto-Afroasiatic*m-r(“river, channel”). Compare South Omotic *mir- (“river”), with reflexes including Aarimɨri(“river, stream”) and Dimemɪ́rɛ(“river”). A possible Semitic cognate is Sabaean𐩣𐩧(mr, “part of an irrigation system”). Possible Cushitic cognates include Borana Oromomērī(“watering trough”), Tsamaimīre(“pond”), and possible Chadic cognates include Falimirə̂(“river”), Muskummìrà(“oxbow lake, marigot”).
From Proto-Afroasiatic. Possible Berber cognates include the forms represented by Kabyleu-mr-an(“sorrows”), a-mur(“colic, stomachache”), and a-mrir(“embarrassment, great difficulty”). Possible Cushitic cognates include Oromomarar(“to be sick”), Baisomarni(“to be sad”), and Sidamomarar-s(“to be sick”). A proposed Omotic cognate is Yemsamer-o(“illness”). Also compare the root Arabicم ر ض(m-r-ḍ, “related to ailment”).
Archaic or greatly restricted in usage by Middle Egyptian. The perfect has mostly taken over the functions of the perfective, and the subjunctive and periphrastic prospective have mostly replaced the prospective.
Declines using third-person suffix pronouns instead of adjectival endings: masculine .f/.fj, feminine .s/.sj, dual .sn/.snj, plural .sn.
Possibly Old Coptic: ⲙⲟⲩⲣ(mour) as proposed by Osing [2] based on a reading in papyrus BM 10808. Alternatively, this occurrence of ⲙⲟⲩⲣ has been read as common Sahidic Coptic: ⲙⲟⲩⲣ(mour) "to bind".[3]
