A plaque is a flat, thin piece of material, often made of metal, wood, or plastic, that is used for:
* Commemorating or honoring someone or something: This is the most common use, with plaques often displayed on buildings, monuments, or walls to recognize achievements, events, or individuals.
* Providing information or directions: Plaques can be used to provide instructions, directions, or warnings.
* Decorating or embellishing an object: Some plaques are purely decorative and can be used to add visual interest to furniture, walls, or other items.
Note: The Tagalog word "plaka" is a direct borrowing from the English word "plaque".
