Play, with these for goalposts? (7)
I believe the answer is:
jumpers
'goalposts?' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Maybe there's an association between them I don't understand?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for jumpers that I've seen before include "They warm you up" , "Garments" , "suitable for spring?" , "get you going when powerless (in > play)" .)
