Crossword Genius

Obtained leave to finish breakfast (3)

Ross

I believe the answer is:

'obtained' is the definition.
('get' can be a synonym of 'obtain')

'leave to finish breakfast' is the wordplay.
'leave' becomes 'go'.
'to finish' suggests the final letters.
The final letter of 'breakfast' is 't'.
'go'+'t'='GOT'

(Other definitions for got that I've seen before include "Obtained", "Caught", "Landed", "Acquired", "came by".)
