Provision rejected in Edinburgh (4)
I believe the answer is:
grub
'provision' is the definition.
The definition and answer can be both to do with ownership as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
'rejected in edinburgh' is the wordplay.
'rejected' says the letters should be written backwards.
'in' says the answer is hidden in the clue.
'burg' can be found hidden inside 'edinburgh'.
'burg' in reverse letter order is 'GRUB'.
Can you help me to learn more?
(Other definitions for grub that I've seen before include "Food (informal)" , "Nosh - larva" , "Caterpillar - food" , "Larva; dig shallowly" , "Common food" .)
