Folk dance recital unaffected (4)
I believe the answer is:
real
'unaffected' is the definition.
(I've seen this in another clue)
'folk dance recital' is the wordplay.
'folk dance' becomes 'reel' (reel is a kind of folk dance).
'recital' shows a homophone (sound like) (as the word might sound when recited aloud).
'reel' sounds like 'REAL'.
(Other definitions for real that I've seen before include "Actual, not imaginary" , "Actual and tangible" , "Genuine, not imitation" , "Not imaginary, genuine" , "Actually existing" .)
