Can be rented – by a nurse? (6)
I believe the answer is:
tender
'a nurse?' is the definition.
(I've seen this before)
'can be rented' is the wordplay.
'can be' indicates anagramming the letters.
'rented' with letters rearranged gives 'TENDER'.
'by' acts as a link.
(Other definitions for tender that I've seen before include "Soft, delicate or loving" , "A gentle kind of bid" , "Compassionate - sore" , "Not hardy (but it may be legal)" , "Not tough - make a bid" .)
