Fur belonging to myself after earl, oddly (6)
I believe the answer is:
ermine
'fur' is the definition.
(ermine is a kind of fur)
'myself after earl oddly' is the wordplay.
'myself' becomes 'mine' (I can't explain this - if you can you should give a lot more credence to this answer).
'after' says to put letters next to each other.
'oddly' means one should take alternating letters (letters in the odd-numbered positions are used).
The alternating letters of 'earl' are 'er'.
'mine' put after 'er' is 'ERMINE'.
'belonging to' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for ermine that I've seen before include "White fur associated with judges" , "Regal fur" , "Fur trimming on royal robes" , "White fur worn by some judges" , "White-coated stoat" .)
