Finished performing Tosca in protective gear? (9)
I believe the answer is:
overcoats
'finished performing tosca in protective gear?' is the definition.
I can't judge whether this definition defines the answer.
'finished performing tosca in' is the wordplay.
'finished' becomes 'over' (over can mean finished or ended).
'performing' indicates anagramming the letters (the letters move around or 'perform').
'in' indicates putting letters inside.
'tosca' is an anagram of 'coats'.
'over' placed inside 'coats' is 'OVERCOATS'.
Can you help me to learn more?
(Another definition for overcoats that I've seen is " things to wear".)
