Nurses entering theatre at surgeon's request (6)
I believe the answer is:
treats
'nurses' is the definition.
The answer and definition can be both related to bodily activities as well as being verbs in their -s form.
Perhaps they are linked in a way I don't understand?
'entering theatre at surgeon's request' is the wordplay.
'entering' indicates a hidden word.
'TREATS' is hidden within 'theatre at surgeons request'.
Can you help me to learn more?
(Other definitions for treats that I've seen before include "Entertains at one's own expense" , "Stands a round, say." , "Gives medical care or pays the bill" , "Behaves towards or deals with in a certain way" , "doctors" .)
