Trimming on robe I claim uncertainly? (6)
I believe the answer is:
ermine
This clue might be a double definition.
'trimming on robe i' is the first definition.
The answer and definition can be both substances as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'claim uncertainly?' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
(Other definitions for ermine that I've seen before include "Ceremonial fur" , "Animal with brown fur that turns white in winter" , "garb for nobility" , "Winter fur of the stoat" , "'Trimming on royal robes, say (6)'" .)
