Work in 2? (7)
I believe the answer is:
operate
'work in 2?' is the definition.
'operate' can be an answer for 'work' (I've seen this before). I'm not sure about the 'in 2?' bit.
'work in 2?' is the wordplay.
'work' becomes 'opera' (musical work).
'in e?' becomes 'te' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'opera'+'te'='OPERATE'
Can you help me to learn more?
(Other definitions for operate that I've seen before include "Perform as surgeon does" , "Control, run, a mcahine say" , "Work, function" , "Work, run" , "Manage, run" .)
