Confine guy's joint and hand (10)
I believe the answer is:
penmanship
'hand' is the definition.
(I know that penmanship is a type of hand)
'confine guy's joint' is the wordplay.
'confine' becomes 'pen' (I've seen this in another clue).
'guy's' becomes 'man's' (guy can informally mean a man).
'joint' becomes 'hip joint' (part of body).
'pen'+'mans'+'hip'='PENMANSHIP'
'and' acts as a link.
(Other definitions for penmanship that I've seen before include "hand" , "Skill in handwriting" , "Calligraphy" , "Writing skill" .)
