Etymology
Origin of loaf1
First recorded before 950; Middle English lo(o)f, Old English hlāf “loaf, bread”; cognate with German Laib, Old Norse hleifr, Gothic hlaifs
Origin of loaf2
An Americanism first recorded in 1825–35; back formation from loafer
Explanation
A loaf is a delicious mass of bread. The kitchen smells great — it must be time to pull that loaf of sourdough out of the oven! If you're a lazy lover of baked goods, your dream vacation might look like this: the chance to loaf around eating one fresh-baked loaf of bread after another. The verb loaf means "laze around doing nothing," but its origin remains a mystery to word experts — although you might look like a bit like a loaf of bread when you loaf on the sofa covered in blankets.
