Is she extremely disruptive, tucking into drink? (7)
I believe the answer is:
ladette
'is she' is the definition.
I can't judge whether this defines the answer.
'extremely disruptive tucking into drink?' is the wordplay.
'extremely' means to remove the middle letters (only the extremes of the word are used).
'tucking into' means one lot of letters goes inside another.
'drink?' becomes 'latte' (type of coffee drink).
'disruptive' with its middle removed is 'de'.
'de' inserted within 'latte' is 'LADETTE'.
Can you help me to learn more?
(Other definitions for ladette that I've seen before include "Party girl?" , "She knocks back too much" , "binge-drinker" , "Young woman with a loutish lifestyle?" , "Loutish girl" .)
