Something, like a piece of
jewellery or an antique, that has been passed down in a family line. These things often have great sentimental value, whether they are worth a lot of money or not.
Heir - a descendant
Loom - a tool
My
Oma left me some
heirloom jewellery when she passed away. Some may think that the jewellery is junk, but it is precious to me.
