Finds the total for the drinks (4)
I believe the answer is:
tots
'drinks' is the definition.
(I have seen 'Little drinks' mean 'tots' so perhaps 'drinks' could also mean 'tots')
'finds the total for the' is the wordplay.
'finds the total' becomes 'ots' (I can't justify this - if you can you should give a lot more credence to this answer).
'for' means one lot of letters go next to another (I've seen this in other clues).
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'ots' put after 't' is 'TOTS'.
Can you help me to learn more?
(Other definitions for tots that I've seen before include "Adds up for the youngsters" , "Party drinks" , "Sailors' drams" , "little people" , "Young children - shorts" .)
