Epps of "House” (4)
I believe the answer is:
omar
'epps of house' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for omar that I've seen before include "and 16 Down: Persian poet" , "Arab" , "old poet" , "- - Sharif (films)" , "- Khayyam, Pers. poet" .)
