One making a drink in a part broken jug? (6)
I believe the answer is:
brewer
'one making a' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'drink in a part broken jug?' is the wordplay.
'drink' becomes 'r' (I can't explain this - if you can you should give a lot more credence to this answer).
'in' means one lot of letters goes inside another.
'a part' says to take the initial letters.
'jug?' becomes 'ewer' (type of vessel).
The initial letter of 'broken' is 'b'.
'b'+'ewer'='bewer'
'r' inserted within 'bewer' is 'BREWER'.
Can you help me to learn more?
(Other definitions for brewer that I've seen before include "one needing teapot?" , "Reference" , "Bookmaker" , "Producer of beer" , "I make tea" .)
