One employed in first ENO Rigoletto? (5)
I believe the answer is:
tenor
'one' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
'employed in first eno rigoletto?' is the wordplay.
'employed in' says the answer is hidden in the clue.
'TENOR' is hidden in the letters of 'first eno rigoletto'.
Can you help me to learn more?
(Other definitions for tenor that I've seen before include "Caruso or Domingo" , "Voice classification of Jose Carreras" , "Singer; drift" , "Pitch range" , "General drift or meaning" .)
