I hesitate to claim such valuable fur (6)
I believe the answer is:
ermine
'valuable fur' is the definition.
(I've seen this in another clue)
'i hesitate to claim' is the wordplay.
I cannot quite see how this works, but
'i' is found in the answer.
'hesitate' could be 'er' (expression used when hesitating) and 'er' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'such' acts as a link.
Can you help me to learn more?
(Other definitions for ermine that I've seen before include "Warm white covering" , "Fur-bearing mammal" , "Fur for an English judge" , "Ceremonial fur" , "White fur from kind of 25 Across - judges may wear it" .)
