Kitchen appliance for an MC (7)
I believe the answer is:
toaster
'kitchen appliance' is the definition.
(toaster is a type of kitchen appliance)
'for an mc' is the wordplay.
'for' becomes 'to' (eg both can mean 'in the opinion of').
'an mc' becomes 'aster' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to'+'aster'='TOASTER'
Can you help me to learn more?
(Other definitions for toaster that I've seen before include "wedding present?" , "Machine for making brown bread?" , "Kitchen device" , "Device using sliced bead" , "At store (anag.)" .)
