Point to inferior scent (5)
I believe the answer is:
spoor
'scent' is the definition.
(thesaurus)
'point to inferior' is the wordplay.
'point' becomes 's' (S is an example).
'to inferior' becomes 'poor' ('poor' can be similar in meaning to 'inferior').
's'+'poor'='SPOOR'
(Other definitions for spoor that I've seen before include "24 [TRAIL]" , "Beast's trail" , "Animal's track/scent" , "Trace" , "Animal track, trail" .)
