They're performed with nothing to spare, possibly (6)

I believe the answer is:

operas

I'm a little stuck... Click here to teach me more about this clue!

'they're performed' is the definition.
The definition suggests an adverb but the answer is not.

'nothing to spare possibly' is the wordplay.
'nothing' becomes 'O' (looks like zero - 0).
'to' means one lot of letters go next to another.
'possibly' indicates an anagram.
'spare' is an anagram of 'peras'.
'o'+'peras'='OPERAS'

'with' acts as a link.

Can you help me to learn more?

(Other definitions for operas that I've seen before include "Musical dramas" , "Plays in which the words are sung" , "Dramatic musicals in which words are sung" , "La Traviata, Aida" , "eg Faust, Salome" .)
