- lead (n.1)
- heavy metal, Old English lead, from West Germanic *loudhom (cognates: Old Frisian lad, Middle Dutch loot, Dutch lood "lead," German Lot "weight, plummet"). The name and the skill in using the metal seem to have been borrowed from the Celts (compare Old Irish luaide), probably from PIE root *plou(d)- "to flow."
