Display exuberant paintings etc, stuck up in eatery (9)
I believe the answer is:
trattoria
'eatery' is the definition.
(thesaurus)
'display exuberant paintings etc stuck up' is the wordplay.
'display' becomes 'air' (air can mean to display or show something).
'exuberant' becomes 'ott' (I am not sure about this - if you are sure you should believe this answer much more).
'paintings etc' becomes 'art' (works of art).
'stuck up' says the letters should be written in reverse.
'air'+'ott'+'art'='airottart'
'airottart' in reverse letter order is 'TRATTORIA'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for trattoria that I've seen before include "Place to eat" , "where Italians eat" , "Italian restaurant" , "Italian eating establishment" .)
