How to use it

'ly'/'cốc' can refer to the cup itself or to a serving of a drink, such as 'một ly cà phê' (a cup of coffee) or 'một cốc nước' (a glass of water). Regional preferences differ, but both are widely understood. Do not use 'chén' for drinks; 'chén'/'bát' are more for bowls or food.

  • Both 'ly' and 'cốc' are common for ordering drinks.
  • 'ly' is more common in the South, 'cốc' in the North, but both are understood.
  • To refer to the cup as an object, use 'cái cốc'.
