Etymology

It is inherited from Proto-Italic *louko- (“sacred grove”), inherited from Proto-Indo-European *lówk-o- (“light place, clearing”), from the root of lūx “light”.[2][1][3] An old inscription has loucom.[2][3] Cognate with Oscan lúvkeí (“in the grove”), Umbrian vukum, Sanskrit लोक (loká, “open space”) and Old High German lōh (“low bushes”).[2][3] Isidore explains it by contraries, a dense grove that keeps out the light, or from the lights burnt there.[4]

Earliest recorded meaning

De Vaan dates it from Plautus, who speaks of the grove of Silvanus outside the wall.[2][3] An early inscription from Spoletium forbids anyone to violate this grove.[3] Köbler dates Plautus c. 250–184 BC.[5]

Semantic evolution

It was a sacred grove, and Cato prescribes the Roman rite for thinning one (lūcum collūcāre).[3] In poetry it was any wood or grove.[3] Several towns were named from groves, as Lūcus Augustī in Gaul.[6][7]

Medieval writers used it of the groves of idolaters cut down by the Christians, and in charters of a wood.[8][9] It survives in place names such as Italian Lugo.[1]
