A good turn is an act of kindness or generosity. It can be as simple as holding a door open for someone, or as grand as donating money to a charity. The term 'good turn' can be broken down into three words: FAVOR (5 letters), FAVOUR (6 letters), and doa (3 letters). FAVOR and FAVOUR are both nouns that refer to an act of kindness or generosity, while doa is an acronym for 'deed of assistance, ' which is another way of saying 'good turn.'
