One put off from playing gig after this? (5,6)
I believe the answer is:
stage fright
'playing gig after this?' is the definition.
The definition suggests a singular noun which matches the answer.
'one put off from' is the wordplay.
I cannot quite see how this works, but
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
'from' could be 'fr' (abbreviation) and 'fr' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for stage fright that I've seen before include "Dramatic nerves" , "Actor's fear" , "Nerves in front of an audience" , "problem for players" , "Pre-performance nerves" .)
