Perhaps Gabriel will get over teaching Albert? (6)
I believe the answer is:
angelo
'albert?' is the definition.
Both the definition and answer are singular nouns.
Maybe there's an association between them I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for angelo that I've seen before include "Man" , "Duke's deputy" , "Shakespearean role" , "See 5" , "Italian male name meaning messenger" .)
