RUSKĀ is a Primitive Quendian root given no signification, except from what can be determined from its derivatives.
 Other etymologies
The related Quenya words russa "red-haired" and russe "(a head or pelt of) red hair" show derivation from another, more basic root *RUS, of which RUSKĀ is obviously an extended form.
Tolkien translates the Quenya word russa as "russet". The English word russet derives from Latin russus "reddish".
There is a possibility that the similarities of both form and sense between the Elvish root and English/Latin words is intentional.
