Golf attendant leaves container (5)
I believe the answer is:
caddy
'container' is the definition.
(caddy is a kind of container)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for caddy that I've seen before include "Give assistance to a professional" , "Golfer's assistant" , "In which Earl Grey may be" , "Storage container for tea" , "Tea box" .)
