Doctor sees new right for worker in theatre (7)
I believe the answer is:
dresser
'worker in theatre' is the definition.
'dresser' can be an answer for 'worker' (dresser is a kind of worker). I'm not certain of the 'in theatre' bit.
'doctor sees new right' is the wordplay.
'doctor' becomes 'dr' (synonyms).
'new' indicates an anagram.
'right' becomes 'r' (common abbreviation).
'sees' anagrammed gives 'esse'.
'dr'+'esse'+'r'='DRESSER'
'for' is the link.
Can you help me to learn more?
(Other definitions for dresser that I've seen before include "Open-shelved cupboard for displaying dishes" , "another" , "Chest of drawers" , "Sideboard - backstage assistant" , "one coming into line?" .)
