A thousand dollars given up by spoilt teenager for course (6)
I believe the answer is:
entree
'for course' is the definition.
(course of a meal)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for entree that I've seen before include "Something that provides access" , "Dish served between fish and meat course" , "formal entrance" , "Starter" , "Dish served between fish and meat courses" .)
