Highest peak in the Alps (4,5)
I believe the answer is:
mont blanc
'highest peak in the alps' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mont blanc that I've seen before include "Highest mountain in the Alps" , "Highest Alpine peak" , "European high point" , "peak form" , "Highest mountain in the?Alps" .)
