Put first pram on back walkway (4)
I believe the answer is:
ramp
'walkway' is the definition.
(I've seen this in another clue)
'put first pram on back' is the wordplay.
'pram' anagrams to 'RAMP'.
Though, I am not clear how the anagram is indicated.
Can you help me to learn more?
(Other definitions for ramp that I've seen before include "Change of level - swindle" , "Inclined walkway" , "Smoothed-out stairs" , "Sloping surface; swindle" , "cheat" .)
