Q. Ambarussa m. “Top-russet”
The mother-name of both of the twins
Amrod and
Amras, though at Fëanor’s insistence, she gave one of them a new mother-name:
Umbarto, which Fëanor changed to the less ominous
Ambarto (PM/353-4). The name is a compound of
amba¹ “up” and
russa “red-haired”, and refers to the red hair of the twins.
