Inclination Conservative has to avoid restraint (4)
I believe the answer is:
ramp
'inclination' is the definition.
(thesaurus)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for ramp that I've seen before include "Sloping passage" , "Short slope" , "It gets travellers off" , "Sloping walkway" , "Inclined plane; swindle" .)
