There's the simple bread that we eat; there's the religious "daily bread"; and there are a hundred and one hidden etymologies for when we eat our words.
The Old English word for bread was hlaf, from which we get loaf; and the old English division of labour was that women made bread and men guarded it. The woman was therefore the hlaf-dige and the man was the hlaf-ward.
Hlafward and Hlafdige
Hlaford and Hlafdi
Lavord and Lavedi

And gritty was not first applied either to dramas or to roads but to dear old, mere old bread.
