A red flag意思

"A red flag" is an English idiom that means a warning or indication of a problem or something to be cautious about. It is often used to describe a situation or behavior that suggests potential danger, trouble, or a cause for concern. The phrase is derived from the practice of raising a red flag as a signal of warning or danger.

For example, if someone is interviewing a potential roommate and the roommate mentions that they've been evicted from their last place, that could be considered a red flag. It suggests that there might be some issue with the person's behavior or lifestyle that could lead to problems if they move in.

In the context of relationships, a red flag might be if someone you're dating reveals that they have a history of controlling behavior or if they become angry very easily. These are signs that the relationship could potentially be unhealthy or problematic.

In the context of investing or business, a red flag might be if a company's financial statements show irregularities or if there are signs of mismanagement. These could be indications that the company is not a good investment or a safe place to work.
