Tell someone the arrangement? (5)
I believe the answer is:
order
This could be a double definition.
'tell someone' is the first definition.
'order' can be an answer for 'tell' (synonyms). I'm unsure of the 'someone' bit.
'arrangement?' is the second definition.
(order is a kind of arrangement)
'the' is the link.
Can you help me to learn more?
(Other definitions for order that I've seen before include "booking" , "Reserved goods" , "Directive for harmony" , "peace" , "rule of law" .)
