* ὕβρις (hýbris): This is often translated as "hubris," and refers to excessive pride, arrogance, and insolence, often leading to a downfall. This is probably the closest single word to a negative form of pride.
* μεγαλοπρέπεια (megaloprepeia): This means "magnificence" or "splendor," and can be associated with a justifiable pride in one's achievements or status. It's a positive form of pride.
* φιλαυτία (philautia): This translates to "self-love" but can carry connotations of excessive self-regard, bordering on narcissism. It's a more self-centered form of pride.
Therefore, depending on the context, ὕβρις (hýbris) is likely the most appropriate if you mean excessive pride, while μεγαλοπρέπεια (megaloprepeia) might be better for a positive, justified pride.
