Run in country producing injury (6)
I believe the answer is:
sprain
'run' is the definition.
(thesaurus)
'in country producing injury' is the wordplay.
'in' indicates putting letters inside.
'country' becomes 'spain' (Spain is a country).
'producing injury' becomes 'r' (I can't justify this - if you can you should believe this answer much more).
'spain' going around 'r' is 'SPRAIN'.
Can you help me to learn more?
(Other definitions for sprain that I've seen before include "Pull" , "Muscle injury caused by wrench." , "unwelcome twist" , "Wrench (limb)" , "Wrench (ligaments)" .)
