Provide a terminus at the town centre (5)
I believe the answer is:
endow
'provide' is the definition.
(I've seen this before)
'a terminus at the town centre' is the wordplay.
'a terminus' becomes 'end' (eg the end of a train line is its terminus).
'at' is a charade indicator (letters next to each other).
'the town centre' becomes 'ow' (central letters of the word 'town').
'end'+'ow'='ENDOW'
(Other definitions for endow that I've seen before include "Provide with a permanent income - perhaps a college" , "provide permanent finance for ..." , "Provide with an income, say a college" , "Provide with a source of income" , "Give money to" .)
