pride [OE] In Old English pryde was ‘excessive self-esteem’, and from medieval times pride was regarded as the first of the Seven Deadly Sins. Also medieval is its use to mean ‘a social group of lions’, although it died out only to be revived in the 19th century. As lions are the kings of beasts, the term was presumably felt to be appropriate for them. Both pride and proud [OE] go back via French to Latin prodesse ‘be of value, be good’. Pride goes (or comes) before a fall [LME] is a reworded version of a sentence from the biblical Book of Proverbs: ‘Pride goeth before destruction, and an haughty spirit before a fall.’

Your pride and joy is the thing you are most proud of; the expression is recorded only from the beginning of the 20th century, but since the Middle Ages something a person is very proud of has been their ‘pride’. Pride and joy may have been suggested from the poem Rokeby (1813) by Sir Walter Scott: ‘See yon pale stripling! when a boy, / A mother’s pride, a father’s joy!’
