Partner held painting (3)
I believe the answer is:
art
'painting' is the definition.
(I've seen this before)
'partner held' is the wordplay.
'held' indicates a hidden word.
'ART' is hidden within 'partner'.
(Other definitions for art that I've seen before include "Works of beauty created by humans" , "Work such as paintings or sculptures" , "Paintings etc." , "Skill in a specified thing" , "Skill, knack" .)
