Corn servings (4)
I believe the answer is:
ears
'corn servings' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ears that I've seen before include "Sense organs" , "Organs of hearing" , "Seed-bearing parts of corn" , "Shakespeare 'Friends, Romans, countrymen, lend me your . . . .'" , "Listening organs" .)
