The Vietnamese phrase "ăn tiệc" means "to attend a banquet" or "to feast." It is commonly used to describe the act of enjoying a meal or celebration, often in a social setting with a variety of foods and drinks.
In more advanced contexts, "ăn tiệc" can also imply celebrating special occasions, such as birthdays, holidays, or anniversaries. You might come across phrases like "ăn tiệc sinh nhật" (birthday party) or "ăn tiệc cưới" (wedding banquet).
While "ăn tiệc" primarily means to feast, the word "ăn" (to eat) can also mean to consume food in general. So, "ăn tiệc" specifically refers to eating in a festive or celebratory context, not just any meal.
