Brought over some Frappuccinos and a tea (5)
I believe the answer is:
cuppa
'a tea' is the definition.
(cuppa is a kind of tea)
'brought over some frappuccinos and' is the wordplay.
'brought over' says the letters should be written backwards.
'some' indicates a hidden word (some of the parts of the word are used).
'appuc' can be found hidden inside 'frappuccinos and'.
'appuc' reversed gives 'CUPPA'.
(Other definitions for cuppa that I've seen before include "Drink of tea (colloq.)" , "Refreshing brew" , "Drink of tea (informal)" .)
