Carry clubs in small container (5)
I believe the answer is:
caddy
I believe this clue is a double definition.
'carry clubs' is the first definition.
(as in to act as a golf caddy)
'small container' is the second definition.
'in' is the link.
(Other definitions for caddy that I've seen before include "course attendant?" , "Golfer's assistant" , "Give assistance to a professional" , "supplier of tea" , "Tea-leaf container" .)
