Talent show: pound to enter (5)
I believe the answer is:
flair
'talent' is the definition.
(flair is a kind of talent)
'show pound to enter' is the wordplay.
'show' becomes 'fair' (fair is a kind of show**).
'pound' becomes 'l'.
'to enter' means one lot of letters goes inside another.
'fair' going around 'l' is 'FLAIR'.
(Other definitions for flair that I've seen before include "Talent; elegance" , "skill" , "Style, talent" , "Natural ability/talent" , "Creative brilliance" .)
