Trianon

Definition: a smaller building on the grounds of a larger estate

The name comes from some structures on the royal grounds in France.

A treaty signed in the Grand Trianon building to end Hungarian involvement in World War I was known as The Treaty of Trianon.

I couldn’t find an raw translation for the word. Google Translate doesn’t believe it’s French, and any etymologies I found just referred to the buildings in France. It might refer to a French hamlet which King Louis purchased to build the original buildings, so they just inherited the name.

Why I Looked It Up

The The Covenant, the homestead on one of the settler farms was called “Trianon.”

Then, in Where'd You Go, Bernadette, an Airstream trailer parked on the grounds of a larger home was jokingly referred to as “Petit Trianon.”
