Code word for the letter R (5)
I believe the answer is:
romeo
'code word for the letter r' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for romeo that I've seen before include "He's a letter read out" , "Latin lover" , "He's on the lookout for it?" , "Lover boy" , "He was known for loving" .)
