Score five times - that's a lot! (3)
I believe the answer is:
ton
This clue might be a double definition.
'score five times' is the first definition.
The answer and definition can be both quantities as well as being singular nouns.
Maybe there's an association between them I don't understand?
'lot' is the second definition.
(I've seen this in another clue)
'that's a' acts as a link.
Can you help me to learn more?
(Other definitions for ton that I've seen before include "Imperial unit of weight" , "2,240 lbs" , "2240lbs" , "See 25" , "Speed" .)
