gilt

Think of an old mirror frame in a grand house. If it is gilt, it has a thin layer of gold on the surface, so it shines and looks rich. This is the most common descriptive use of the word, especially for frames, furniture, and the edges of books.

But gilt is not only about decoration. In farming, a gilt is a young female pig, especially one that has not had piglets yet. In British finance, gilts are government bonds. So the word can take you from golden surfaces to the farmyard, and even to the world of money.

Gilt has several lives as a word, and they are not closely related. First, it is the past form and past participle of gild, and it is also used as an adjective for something covered with a thin layer of gold. Think of a gilt frame, a gilt mirror, or gilt lettering on a book cover. In this sense, the word points to a bright, rich surface rather than something made of solid gold.

There is also an important noun sense in agriculture. A gilt is a young female pig, usually one that has not yet had a litter. Farmers use the word in a practical, everyday way: one pig in the pen may be a sow, another may still be a gilt.

In British English, especially in finance, a gilt is also a government bond. The name comes from the old practice of printing certificates with gilded edges, which gave rise to the term gilt-edged securities. Today, people often shorten that to gilts when talking about UK government debt.

Because of its link with gild, the word may sometimes suggest shine, status, or beauty, but that is only one branch of its story. Depending on the context, gilt may describe a gold-covered object, name a young female pig, or refer to a British government bond. The sentence around it tells you which path the word is taking.
