lignum

lignum uital.-lat.

From Proto-Italic *legnom, from Proto-Indo-European *leǵ-no-m (“that which is collected”), from *leǵ- (“to collect”), with the Italic form interpreted as "wood collected for firemaking".

An alternative derivation from Proto-Indo-European *legʰ- (“to lie”), and associated interpretation as "stray wood", seems equally possible, phonetically and semantically.
