Model to get progressively larger employment (7)
I believe the answer is:
waxwork
'model' is the definition.
(thesaurus)
'get progressively larger employment' is the wordplay.
'get' says to put letters next to each other.
'progressively larger' becomes 'wax' (I am not sure about this - if you are sure you should believe this answer much more).
'employment' becomes 'work' (synonyms).
'wax' next to 'work' is 'WAXWORK'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for waxwork that I've seen before include "Figure made from candle material" , "Still representation of a famous person" , "Image" , "Candle material effigy" , "Life-sized representation of a celebrity" .)
