Slope seen after time in hike (5)
I believe the answer is:
tramp
'hike' is the definition.
(tramping is a kind of hiking)
'slope seen after time' is the wordplay.
'slope' becomes 'ramp' (I've seen this before).
'seen after' says to put letters next to each other.
'time' becomes 't' (abbreviation).
'ramp' after 't' is 'TRAMP'.
'in' acts as a link.
(Other definitions for tramp that I've seen before include "Footslog" , "Lady or gentleman of the road or roving ship" , "Traveller" , "Disreputable wanderer" , "Walk heavily - steamer" .)
