Finally accept inclination to provide public transport (5)
I believe the answer is:
tramp
'public transport' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'finally accept inclination' is the wordplay.
'finally' says to take the final letters.
'inclination' becomes 'ramp' (an inclined surface).
The last letter of 'accept' is 't'.
't'+'ramp'='TRAMP'
'to provide' is the link.
Can you help me to learn more?
(Other definitions for tramp that I've seen before include "one unlikely ever to have a mortgage!" , "Disreputable wanderer" , "Heavy footsteps" , "Beggar or vagrant" , "woman who's promiscuous?" .)
