Arrangement to request food? (5)
I believe the answer is:
order
I believe this is a triple definition!
'arrangement' is the first definition.
(order is a kind of arrangement)
'to' is the second definition.
(thesaurus)
'request food?' is the third definition.
(I've seen this in another clue)
(Other definitions for order that I've seen before include "Type of column" , "pattern" , "demand" , "rule of law" , "Enjoin in harmony" .)
