To crash in the Alps must be a blow (4)
I believe the answer is:
slap
'blow' is the definition.
(I know that slap is a type of blow)
'to crash in the alps must be a' is the wordplay.
'alps' anagrams to 'SLAP'.
But, I'm unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for slap that I've seen before include "Mild punishment" , "A blow among pals" , "Blow (in face, on back, wrist)" , "Hit with an open hand" , "Hit with the palm" .)
