Place for a stirrup (3)
I believe the answer is:
ear
'place for a stirrup' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ear that I've seen before include "Organ involved with balance" , "Seed-bearing part of corn" , "See 8" , "Shell-like; corn" , "It's used in hearing" .)
