Sindarin for "Cloak of the Galadhrim"

coll = cloak. Thingol = grey-cloak or grey-mantle.

Galadhrim = the tree-people, i.e., the people of Lórien.

My best guess is Galadhrimgol.

Comments?

I'd use en "of the" instead, thus:

coll e-ngaladhrim
Cloak [of the] Galadhrim

aldaleon

coll e-ngaladhrim or coll en-galadhrim ??
