Run, pass, turn poorly again? (7)
I believe the answer is:
relapse
'turn poorly again?' is the definition.
I can't tell whether this definition defines the answer.
'run pass' is the wordplay.
I cannot quite see how this works, but
'run' could be 'r' (cricket abbreviation) and 'r' is located in the answer.
'pass' could be 'elapse' (synonyms) and 'elapse' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for relapse that I've seen before include "fall into sin" , "Sink back into illness" , "Slip back to former state" , "Fall back like leapers" , "Fail to maintain progress" .)
