rectitude - virtue
The formal word ‘rectitude’ refers to the quality or attitude displayed by people who conduct themselves in a way that is honest, moral, and in line with social conventions. For the most part, this is seen as a highly positive way of being and elicits praise and admiration. However, some may judge such people to be dull and overly righteous.
