Model, short type, with one child of five (9)
I believe the answer is:
mannequin
'model' is the definition.
(synonyms)
'short type with one child of five' is the wordplay.
'short' means to remove the last letter.
'type' becomes 'manner'.
'with' is a charade indicator (letters next to each other).
'one child of five' becomes 'quin' (I've seen this before).
'manner' with its last letter taken away is 'manne'.
'manne'+'quin'='MANNEQUIN'
(Other definitions for mannequin that I've seen before include "Display dummy" , "Shop's dummy" , "Life-size dummy for displaying clothes" , "fashion model" , "Dummy figure" .)
