Patience maybe displayed by manager in firm with rising ambition (5,5)
I believe the answer is:
comic opera
'patience maybe' is the definition.
(Patience is an example)
'manager in firm with rising ambition' is the wordplay.
'manager' becomes 'coper' (someone who manages or copes).
'in' indicates putting letters inside.
'firm with' becomes 'co' (a firm is a company. I am not sure about the 'with' bit.**).
'rising' says the letters should be written in reverse (going up in a down clue).
'ambition' becomes 'aim' (I've seen this before).
'aim' reversed gives 'mia'.
'co'+'mia'='comia'
'coper' put into 'comia' is 'COMIC OPERA'.
'displayed by' is the link.
(Other definitions for comic opera that I've seen before include "Eg, The Barber of Seville" , "Milton perhaps" , "Amusing stage work" , "Amusing stage show" , "The Marriage of Figaro, for instance" .)
