Wretched ends to hike up Alps or Fuji? (6)
I believe the answer is:
apples
'fuji?' is the definition.
(type of apples)
'wretched ends to hike up alps' is the wordplay.
'wretched' indicates an anagram.
'ends to' says to take the final letters (I've seen 'end to' mean this).
The last letters of 'hike up' are 'ep'.
'ep'+'alps'='epalps'
'epalps' with letters rearranged gives 'APPLES'.
'or' is the link.
(Other definitions for apples that I've seen before include "Loud sharp cry" , ""____, cherries, hops and women"" , "Divinely influenced" , "Crisp fruits" , "PS, leap up for the fruit" .)
