Sprinter primarily runs in discomfort due to this? (6)
I believe the answer is:
sprain
'this?' is the definition.
The definition suggests a singular noun which matches the answer.
'sprinter primarily runs in discomfort' is the wordplay.
'primarily' suggests taking the first letters.
'runs' becomes 'r' (cricket abbreviation).
'in' indicates putting letters inside.
'discomfort' becomes 'pain' (I have seen 'Physical discomfort ' mean 'pain' so perhaps 'discomfort' could also mean 'pain').
The first letter of 'sprinter' is 's'.
'r' inserted into 'pain' is 'prain'.
's'+'prain'='SPRAIN'
'due to' is the link.
Can you help me to learn more?
(Other definitions for sprain that I've seen before include "Muscular injury caused by wrench" , "Injury to the ankle, say" , "Wrench; in rasp (anag.)" , "Muscle injury caused by wrench." , "Wrench, dislocate" .)
