The Vietnamese word "tai hại" is an adjective that means "disastrous" or "catastrophic." It is used to describe situations, events, or actions that cause great harm or damage, often with serious consequences.
Simple Example: "Quyết định đó đã dẫn đến hậu quả tai hại."
(That decision led to disastrous consequences.)
Advanced Example: "Thiên tai đã gây ra thiệt hại tai hại cho nhiều vùng nông thôn."
(Natural disasters have caused catastrophic damage to many rural areas.)
While "tai hại" primarily means disastrous or catastrophic, it can also imply something that is harmful or detrimental. It focuses on the severity of the damage or the seriousness of the situation.
