Romeo embraced by a steamy lover (7)
I believe the answer is:
'lover' is the definition.
(I know that amorist is a type of lover)
'romeo embraced by a steamy' is the wordplay.
'romeo' becomes 'r' (phonetic alphabet: alpha, bravo, charlie etc.).
'embraced by' means one lot of letters goes inside another.
'steamy' becomes 'moist' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'r' placed into 'amoist' is 'AMORIST'.
Can you help me to learn more?
(Other definitions for amorist that I've seen before include "one loves" , "Writer on love" , "Ovid, for one" , "Lover" .)
