Lime thrown a long way (4)
I believe the answer is:
mile
'a long way' is the definition.
(I've seen this in other clues)
'lime thrown' is the wordplay.
'thrown' indicates anagramming the letters.
'lime' with letters rearranged gives 'MILE'.
(Other definitions for mile that I've seen before include "1.61km" , "5280 feet" , "'A miss is as good as a ....'" , "Imperial length" , "Unit of length" .)
