Humble pie

The phrase ‘to eat humble pie’, i.e. to apologise, derives from a dish that originated in Britain in the medieval to early modern period known as ‘umble pie’. The dish was a simple pie made from offal that was mainly eaten by the lower classes and its name came from the fact that the old English word for innards was umbles. Due to the humble nature of the dish and the dialect which tended to drop the h, a link was made between umble pie and humble and the phrase ‘eating humble’ was born.
