There are several synonyms that can be used to describe vain people. Some of these are narcissistic, conceited, egotistical, self-obsessed, self-centered, boastful, and arrogant. Vain people are those who are overly concerned with their appearance, achievements, or status, which they often flaunt to gain attention and praise from others. They have an inflated sense of self-importance and believe that they are better than others. This kind of behavior can be extremely annoying and even harmful, as it can lead to a lack of empathy towards others. Therefore, it is essential to recognize the signs of vanity in oneself and others to cultivate a more compassionate and enlightened approach to life.
