Unusual merit in these ends? (7)
I believe the answer is:
termini
'these ends?' is the definition.
(terminus is a kind of end)
'unusual merit in' is the wordplay.
'unusual' indicates an anagram.
'merit'+'in'='meritin'
'meritin' is an anagram of 'TERMINI'.
(Other definitions for termini that I've seen before include "goals" , "limits of service" , "Interim (anag.)" , "Railway ends" , "Rail stations mainly in city centres" .)
