Breadcrumb (noun)

1. A navigation aid, typically in the form of a series of links, that shows the user's location within a website or application.
2. Small pieces of bread that are used as a coating for food, typically meats or fish, before they are fried.

Origin:

The word "breadcrumb" is thought to come from the fact that breadcrumbs were traditionally used as a way to mark a trail so that one could find their way back, similar to hansel and gretel leaving breadcrumbs in the fairy tale. the word first appears in the late 17th century in the meaning of "small piece of bread" and later in the early 20th century to refer to a navigation aid.

Examples:

1. The website uses breadcrumbs to help users navigate through the different sections.
2. I used breadcrumbs to coat the chicken before frying it.
3. The breadcrumb trail on the top of the website helps you keep track of your location.
4. I mixed together some breadcrumbs, parmesan cheese, and herbs to make a coating for the fish.
5. The breadcrumb navigation allows users to easily retrace their steps in the website.
