Model male, born one of five (9)
I believe the answer is:
mannequin
'model' is the definition.
('mannequin' can be a synonym of 'model')
'male born one of five' is the wordplay.
'male' becomes 'man' (man is a kind of male).
'born' becomes 'ne'.
'one of five' becomes 'quin' (I've seen this before).
'man'+'ne'+'quin'='MANNEQUIN'
(Other definitions for mannequin that I've seen before include "Life-size dummy for displaying clothes" , "fashion model" , "Display dummy" , "Shop's dummy" , "Dummy figure" .)
