Witness putting Murphy on spot for hearing? (9)
I believe the answer is:
spectator
'witness' is the definition.
(I know that witness can be written as spectator)
'murphy on spot for hearing?' is the wordplay.
I cannot really understand how this works, but
'on' could be 'at' (I've seen this in other clues) and 'at' is located in the answer.
'for' could be 'to' (eg both can mean 'in the opinion of') and 'to' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'putting' is the link.
Can you help me to learn more?
(Other definitions for spectator that I've seen before include "I attend sporting event" , "one found at ground?" , "given weekly inspection?" , "weekly publication" , "weekly magazine?" .)
