Race round track regularly, finding concierge (9)
I believe the answer is:
caretaker
'concierge' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'race round track regularly' is the wordplay.
'race' becomes 'career' (career can mean to run or move out of control).
'round' means one lot of letters goes inside another.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
The alternating letters of 'track' are 'tak'.
'career' enclosing 'tak' is 'CARETAKER'.
'finding' is the link.
Can you help me to learn more?
(Other definitions for caretaker that I've seen before include "Custodian, keeper" , "exercising temporary control" , "Janitor" , "School worker, perhaps" , "Warden" .)
