Repairman taking in a ramble (7)
I believe the answer is:
meander
'ramble' is the definition.
(thesaurus)
'repairman taking in a' is the wordplay.
'repairman' becomes 'mender' (mender is a kind of repairman).
'taking in' means one lot of letters goes inside another.
'mender' going around 'a' is 'MEANDER'.
(Other definitions for meander that I've seen before include "Wandering direction" , "roundabout route" , "Red mane (anag) - roam aimlessly" , "Renamed in order to wander in leisurely way" , "Renamed (anag)" .)
