Lover’s letter read out (5)
I believe the answer is:
romeo
I believe this clue is a double definition.
'lover's' is the first definition.
(I've seen this before)
'letter read out' is the second definition.
(NATO codeword)
(Other definitions for romeo that I've seen before include "Juliet's lover of Verona" , "He's a letter read out" , "Don Juan" , "Code word for the letter R" , "Shakespearean character" .)
