Inclination to break pram (4)
I believe the answer is:
ramp
'inclination' is the definition.
(an inclined surface)
'break pram' is the wordplay.
'break' indicates anagramming the letters.
'pram' with letters rearranged gives 'RAMP'.
'to' is the link.
(Other definitions for ramp that I've seen before include "One's inclined" , "Inclination - swindle" , "It gets travellers off" , "aircraft steps?" , "motorway access road" .)
