Nurse embracing Romeo, in a fashion (5)
I believe the answer is:
trend
'fashion' is the definition.
(I've seen this in another clue)
'nurse embracing romeo' is the wordplay.
'nurse' becomes 'tend' (tend can mean to nurse or look after).
'embracing' is an insertion indicator.
'romeo' becomes 'R' (phonetic alphabet: alpha, bravo, charlie etc.).
'tend' going around 'r' is 'TREND'.
'in a' acts as a link.
(Other definitions for trend that I've seen before include "Style, vogue" , "The way things are going?" , "Direction, tendency" , "Vogue, tendency" , "swing" .)
