Odd props tend to have sat for art (5)
I believe the answer is:
posed
'sat for art' is the definition.
'posed' can be an answer for 'sat' ('pose' can be a synonym of 'sit'). I'm not certain of the 'for art' bit.
'odd props tend' is the wordplay.
'odd' indicates alternate letters.
'props'+'tend'='propstend'
The alternate letters of 'propstend' are 'POSED'.
'to have' is the link.
Can you help me to learn more?
(Other definitions for posed that I've seen before include "Struck attitude, perhaps for painter" , "Presented (a question)" , "Took a stance" , "Faced the camera" , "Presented (a problem)" .)
