"May I have a cup of tea?"
Translation:Ga i baned?
ga i baned o de is accepted as well. The usual meaning of paned is 'a cup of tea', if no other content is specified.
'Ga i panad' is a common abreviation to ask for either a cup of tea or for a cup of coffee. But technically you should specify 'ga i panad o de' or 'ga i panad o cofi'. To ask for a cup of hot chocolate, you'd normally just ask for hot chocolate which would be 'ga i siocled boeth'
