Some start showing skills (4)
I believe the answer is:
arts
'skills' is the definition.
(art can mean a skill or talent)
'some start showing' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'ARTS' is hidden within 'start showing'.
(Other definitions for arts that I've seen before include "Literature, music etc." , "Tricks" , "Cultural subjects; skills" , "'Poetry, music, painting (4)'" , "Eg, painting, sculpture" .)
