Time and inclination to be a wanderer (5)
I believe the answer is:
tramp
'a wanderer' is the definition.
(tramp is a kind of wanderer)
'time and inclination' is the wordplay.
'time' becomes 't' (abbreviation).
'and' is a charade indicator (letters next to each other).
'inclination' becomes 'ramp' (an inclined surface).
't'+'ramp'='TRAMP'
'to be' acts as a link.
(Other definitions for tramp that I've seen before include "A boat; a vagrant" , "Tread heavily (on)" , "Merchant ship" , "Vagabond, hobo" , "Trudge; vagrant" .)
