Possibly miss standing in party heels with cup getting drunk (6,7)
I believe the answer is:
supply teacher
'possibly miss standing' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'party heels with cup getting drunk' is the wordplay.
'with' means one lot of letters go next to another.
'getting drunk' indicates anagramming the letters.
'party'+'heels'+'cup'='partyheelscup'
'partyheelscup' anagrammed gives 'SUPPLY TEACHER'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for supply teacher that I've seen before include "Stand-in educator" , "Temporary educator" , "Stopgap in school" , "A short-term replacement" .)
