plud : lead
The Illunse word for lead (metal) is plud. Plud is a rare last name. PLUD is an acronym for People Like Us, Dear (British middle-class slang).
This word is a mixture of the Latin word for lead which is plumbum, and the Old English word for lead which is lead (same as Modern English).
My previous word for lead was ledum. That word seemed too Latin-ish.
Lead is a soft, malleable, heavy metal. Its atomic symbol is Pb, from the Latin plumbum. Lead is one of the seven metals known from antiquity.
