From
Demotic r mr , ultimately from
Egyptian ( r ,
“ regarding, towards ” ) +
mrw . The interpretation of
mrw is unclear; Černý considers it to be
( mrw ,
“ desert ” ) , while Vycichl equates it with
( mrw ) , a variant form of
( mryt ,
“ riverbank, quay, harbor ” ) , which fits better with the Coptic evidence semantically but perhaps not phonetically. By
surface analysis ,
ⲉ- ( e- ,
“ to ” ) +
ⲙⲏⲣ ( mēr ,
“ (opposite) shore ” ) .
ⲉⲙⲏⲣ • (emēr )
( Bohairic ) to the other side (of), over , across , beyond
