Plural of dignity; the state of being worthy of respect, or high offices and ranks of honor.
From 'dignity' (from Latin 'dignitas'), plus the plural '-ies'. The word can mean both the abstract quality and the concrete offices/positions held by important people.
In medieval texts, 'dignities' literally meant the high church offices themselves—Archbishop, Bishop, Canon—making rank and title inseparable from the virtue they supposedly represented!
