Fallow
Etymology
From Old English "fealg" ("ploughed land, harrow"). It is a different word from the "fallow" in "fallow deer," which comes from "fealu" ("pale yellowish-brown") — a coincidence of spelling.
adjective · /FAL-oh/
Of farmland, ploughed but left unsown for a season or more to restore fertility; figuratively, resting but full of potential.
What it names
Productive rest — the deliberate pause that renews — a rich metaphor for creative or personal downtime.
Example
He let the project lie fallow for a year and returned to it renewed.
