Definição e Significado de "threshold"

What is a "threshold"?

A threshold is the bottom part of a door frame that sits on the floor and serves as the transition between two spaces, such as from outside to inside a building. It helps to support the door and can also provide a seal against drafts, moisture, and dirt. Thresholds are often made from materials like wood, metal, or stone, and they may have a raised or flat design. In addition to their practical purposes, thresholds can add to the overall appearance of the doorway, enhancing the style of the entrance.
