Mehri

mīrət - to be red-hot (ML 270)

Proto-MSA
*mrt - to be red-hot (Kogan 2015:564)
The origin of Proto-MSA *mrt ‘to be red-hot’ is unknown. The presence of mrat ‘glühen’ in the Arabic of Dhofar (Rhodokanakis 55) may be due to the MSA influence. Contra Rhodokanakis, there is hardly any connection between the present root and Arb. mart- ‘a waterless desert in which there is no herbage’ (Lane 2703). (Kogan 2015:564)
