Nyereg

Nyereg is a Hungarian noun meaning saddle. The most common sense is the seat for a rider mounted on a horse or other riding animal, typically made of leather or synthetic materials and attached to the animal's back with a girth. There are many varieties designed for different activities, including English, dressage, jumping, and Western saddles, as well as pack saddles used to carry loads.

The term also refers to the bicycle saddle, a padded seat attached to the bicycle's seat post that supports the rider while cycling. Bicycle saddles vary in shape, padding, and width to suit different riding styles and ergonomic needs.

In geography, nyereg denotes a saddle or col: a low, saddle-shaped pass between valleys or between mountain ridges. Such features form natural routes for trails and roads and are often exploited as mountain passes or crossings.

In mathematics and related fields, nyereg or nyeregpont is used to describe a saddle point, a point in a multivariable function that is a minimum along some directions and a maximum along others. This concept is central in calculus, optimization, and game theory.
