Self-conceit is defined as an exaggerated sense of self-importance or an excessively high opinion of oneself. Synonyms that can be used instead of self-conceit include narcissism, vanity, arrogance and egotism. Narcissism refers to self-obsession and excessive admiration of oneself while vanity is a preoccupation with one's appearance. Arrogance is an attitude that displays superiority over others while egotism is similar to self-conceit as it denotes an inflated sense of self-worth. Any of these synonyms can be used to describe someone who thinks too highly of themselves, often to the detriment of their relationships with others. It is important to avoid these negative traits and cultivate an attitude of humility and self-awareness.
