Rose paid for the drinks (5)
I believe the answer is:
stood
'rose' is the definition.
(I've seen this before)
'paid for the drinks' is the wordplay.
'paid' becomes 'sod' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'for' becomes 'to' (eg both can mean 'in the opinion of').
'the drinks' means one lot of letters goes inside another.
'sod' enclosing 'to' is 'STOOD'.
Can you help me to learn more?
(Other definitions for stood that I've seen before include "Remained upright" , "Paid" , "Was situated" , "Tolerated; stayed upright" , "Was a candidate for election" .)
