means A dull silvery-gray alloy made mostly of tin, hardened with metals like copper, antimony, or historically lead, long used for tankards, plates, and tableware.

from From Middle English 'pewtre,' borrowed from Old French 'peutre,' which traces back to an unrecorded Vulgar Latin form likely related to 'plumbum,' the Latin word for lead — fitting, since old pewter often carried a lead content. The deeper roots are murky, but the lead connection echoes through every European version of the name.
