Friend is coming, carrying plate (4)
I believe the answer is:
disc
'plate' is the definition.
(disc is a kind of plate)
'friend is coming carrying' is the wordplay.
'carrying' indicates a hidden word.
'DISC' can be found hidden inside 'friend is coming'.
(Other definitions for disc that I've seen before include "Circular flat structure in the spine" , "Layer of cartilege between vertebrae" , "Body without limbs" , "In Olympic event" , "Capital of India" .)
