An earlier name for S. Nenning, the river flowing past the haven of Eglorest, marked Ilkorin and translated “Elf-river” in The Etymologies (Ety/ELED). It is likely an elaboration of Ilk. Egla “Elf”. Earlier still the river was named Eldor (SM/227), perhaps containing the earlier (rejected) Ilkorin word Ilk. Eld “Elf”.
