Paddy’s food (4)
I believe the answer is:
rice
This clue is a double definition.
'paddy's' is the first definition.
(thesaurus)
'food' is the second definition.
(rice is a kind of food)
(Other definitions for rice that I've seen before include "Cereal grain" , "Cereal grown in paddy fields" , "Asian staple food" , "Cereal plant" , "Seeds from the paddy field" .)
