Nurse in advance, let’s suppose? (7)
I believe the answer is:
pretend
'suppose?' is the definition.
(thesaurus)
'nurse in advance let's' is the wordplay.
I cannot really see how this works, but
'nurse' could be 'tend' (I've seen this before) and 'tend' is present in the answer.
The remaining letters 'pre' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for pretend that I've seen before include "Dissemble" , "Simulate - make up" , "Make believe - imply falsely" , "Imagined" , "Simulated" .)
