He has the skills to make a suit (6)
I believe the answer is:
hearts
'a suit' is the definition.
(I've seen this before)
'he has the skills' is the wordplay.
'has' says to put letters next to each other.
'the skills' becomes 'arts' (I've seen this before).
'he'+'arts'='HEARTS'
'to make' is the link.
(Other definitions for hearts that I've seen before include "Card suits in bodies" , "Card suit and essential organs" , "Body pumps" , "Major suit at cards" , "Suit for vital organs" .)
