heirloom

In popular usage, an heirloom is something that has been passed down for generations through family members. Examples are a family bible, antiques, weapons or jewellery. The term originated with the historical principle of an heirloom in English law, a chattel which by immemorial usage was regarded as annexed by inheritance to a family estate. Loom originally meant a tool. Such genuine heirlooms were almost unknown by the beginning of the twentieth century.
