Succotash morsel (4)
I believe the answer is:
lima
'succotash morsel' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lima that I've seen before include "Mail it to Peruvian city" , "Mail to Peru's capital" , "Kind of bean" , "city (like 22)" , "Peruvian capital" .)
