Romeo and Oscar in bath with a gloomy singer (10)
I believe the answer is:
troubadour
'singer' is the definition.
(I know that troubadour is a type of singer)
'romeo and oscar in bath with a gloomy' is the wordplay.
I cannot really understand how this works, but
'romeo' could be 'r' (phonetic alphabet: alpha, bravo, charlie etc.) and 'r' is located in the answer.
'oscar' could be 'o' (phonetic alphabet: alpha, bravo, charlie etc.) and 'o' is found within the answer.
'bath' could be 'tub' (synonyms) and 'tub' is present in the remaining letters.
'a' is found in the answer.
'gloomy' could be 'dour' (I've seen this in other clues) and 'dour' is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for troubadour that I've seen before include "Minstrel" , "composer of lyrics" , "love poet" , "Poet-singer" , "Mediaeval singer-poet" .)
