One makes music and drink around gutted boozer (8)
I believe the answer is:
clarinet
'one makes music' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'drink around gutted boozer' is the wordplay.
'drink' becomes 'claret' (claret is a kind of drink).
'around' indicates putting letters inside.
'gutted' suggests removing the centre (to gut something is to remove its insides).
'boozer' becomes 'inn'.
'inn' with its centre removed is 'in'.
'claret' placed around 'in' is 'CLARINET'.
'and' is the link.
Can you help me to learn more?
(Other definitions for clarinet that I've seen before include "Find an instrument in claret" , "Musical wind instrument as played by Benny Goodman" , "Woodwind instrument - Artie Shaw played one" , "musician" , "Music-maker" .)
