Am with old Queen and I may ring for coffee (9)
I believe the answer is:
americano
'for coffee' is the definition.
(type of coffee drink)
'am with old queen and i may ring' is the wordplay.
'with' says to put letters next to each other.
'old queen' becomes 'ER' (Elizabeth Regina, ie Queen Elizabeth).
'and' means one lot of letters go next to another.
'may' becomes 'can' (synonyms).
'ring' becomes 'O' (letter resembling a ring).
'am'+'er'+'i'+'can'+'o'='AMERICANO'
(Other definitions for americano that I've seen before include "Style of coffee" , "Espresso diluted with hot water" , "drink" .)
