At some distance from Rodney (6)
I believe the answer is:
yonder
'at some distance' is the definition.
Both the definition and answer are adverbs. Maybe you can see an association between them that I can't see?
'from rodney' is the wordplay.
'from' indicates anagramming the letters (the anagram comes from the same letters).
'rodney' with letters rearranged gives 'YONDER'.
Can you help me to learn more?
(Other definitions for yonder that I've seen before include "Distant but within sight" , "In that direction" , "that one" , "Rodney (anag.)" , "See Rodney over there" .)
