Case of Drambuie for all that come out (5)
I believe the answer is:
debut
'that come out' is the definition.
(I've seen this in another clue)
'case of drambuie for all' is the wordplay.
'case of' says to hollow out the word (remove centre letters) (like emptying a case).
'for all' becomes 'but' (I can't justify this - if you can you should give a lot more credence to this answer).
'drambuie' with its middle taken out is 'de'.
'de'+'but'='DEBUT'
Can you help me to learn more?
(Other definitions for debut that I've seen before include "Aurora" , "Initial appearance" , "First appearance, a coming-out" , "Introduction" , "First public appearance of performer" .)
