If you've ever had a set of stationery with your initials printed on it, you know what a monogram is — it's those three letters at the top.
When you buy a towel, a blanket, or a sweater you can often pay a little extra for a monogram, to get the initials of your first, middle, and last names embroidered on them. Writing paper, wedding invitations, envelopes, and other paper goods are commonly printed with a monogram — or monogrammed. Fancy silverware can also be imprinted with a monogram, as can gold and silver jewelry. The root is Greek, monogrammon, which means "intertwined letters."
