The Vietnamese word "biếng ăn" refers to a condition where a person, especially a child, has a poor appetite and does not want to eat. It can be translated to "lack of appetite" in English. In a more serious context, it can also relate to a medical condition known as "anorexia."
Thằng bé này đang bị biếng ăn.
(This boy is experiencing a lack of appetite.)
Khi bị bệnh, tôi thường bị biếng ăn.
(When I am sick, I often have a poor appetite.)
In a more advanced context, you might discuss "biếng ăn" in relation to psychological or health issues. For example, it could be part of a discussion on how stress or depression can lead to a lack of appetite.
While "biếng ăn" mainly refers to a lack of appetite, in some contexts it might imply being picky or selective about food, which can be seen as a behavioral issue, especially in children.
