Floozie back to Rhode Island opening authentic Italian restaurant (9)
I believe the answer is:
trattoria
'italian restaurant' is the definition.
(I've seen this in another clue)
'floozie back to rhode island opening authentic' is the wordplay.
'floozie back' becomes 'trat' (I can't explain this - if you can you should give a lot more credence to this answer).
'rhode island' becomes 'ri' (US postal abbreviation).
'opening' indicates taking the first letters.
The initial letter of 'authentic' is 'a'.
'trat'+'to'+'ri'+'a'='TRATTORIA'
Can you help me to learn more?
(Other definitions for trattoria that I've seen before include "Italian restaurant" , "where Italians eat" , "Place to eat" , "Italian eating establishment" .)
