Red flag

A "red flag" is a warning sign indicating that something may be problematic or cause concern. It’s often used to identify issues early on, whether in relationships, job situations, or other areas. Recognizing red flags helps individuals make informed decisions and take precautions before problems deepen. For example, repeated dishonesty or controlling behavior might be red flags in a relationship. Overall, red flags serve as signals to pay closer attention and consider whether the situation is healthy or warrants further investigation.
