rꜥ-ḏd.f

rꜥ (“Ra”) +‎ ḏd (“stability, lastingness”) +‎ .f (“his”), thus ‘Ra is his lastingness’. Possibly, if the name is written with honorific transposition, it could also be ḏd (“endures”) +‎ .f (“he”) +‎ rꜥ (“Ra”), thus ‘He endures, (namely) Ra’; however, both the Greek rendering of the name and the meaning support the former interpretation.
