Mile away from linden tree (4)
I believe the answer is:
lime
'linden tree' is the definition.
(synonyms)
'mile away' is the wordplay.
'away' indicates anagramming the letters (letters move away from their original places).
'mile' with letters rearranged gives 'LIME'.
'from' is the link.
(Other definitions for lime that I've seen before include "Yellowish-green" , "Type of stone" , "White substance used in cement" , "Another name for the linden tree" , "Hang about in Jamaica" .)
