Purchased a branch on time (6)
I believe the answer is:
bought
'purchased' is the definition.
('buy' can be a synonym of 'purchase')
'a branch on time' is the wordplay.
'a branch' becomes 'bough' (bough is a kind of branch).
'on time' becomes 't' (abbreviation. I am not sure about the 'on' bit.).
'bough'+'t'='BOUGHT'
Can you help me to learn more?
(Other definitions for bought that I've seen before include "Obtained" , "paid for" , "Purchased" , "Puchased" .)
