A "bonnet" is a type of headwear that typically covers the head and ties under the chin. It is often associated with children and women, especially in historical contexts. Bonnets can be made from various materials, including fabric and straw, and are designed to provide protection from the sun or cold weather. In automotive terms, the "bonnet" refers to the hinged cover that rests over the engine compartment of a vehicle. This part is crucial for protecting the engine and allowing access for maintenance. In some regions, it is also known as the hood.
