Etymology
Origin of fallow1
1275–1325; Middle English falwe; compare Old English fealga, plural of *fealh, as gloss of Medieval Latin occas harrows
Origin of fallow2
before 1000; Middle English fal ( o ) we, Old English fealu; cognate with German falb
Explanation
Something that is fallow is left unused. If you’re smart but lazy, someone might say you have a fallow mind. We use the word to talk about any unused resource, it started as a work about land. Fallow comes from the old English word for plowing, and refers to the practice of leaving fields unplowed in rotation — when a field lies fallow, the soil regains nutrients that are sucked up by over-planting.
