- In the context of art and culture, the culture of the indigenous peoples of the northern polar region of the earth, including the Arctic Ocean and the northernmost parts of Asia, Europe, and North America. The term may also refer to the animals, plants, climate, geology, geography, and oceanography of the area.
- Refers to the cultures of the continent of North America, which is bounded by the Atlantic Ocean, the Pacific Ocean, the Arctic Circle, and Central America. In classifications schemes based on physical geography, Central America, and North America are parts of the same continent.
- Any relatively insoluble organic, inorganic, natural or artificial substance that imparts a color to another substance or mixture and always appears as the same specific color when viewed in white light. It is the constituent of paint or ink that provides the color. Distinguished from a dye, which is soluble in the vehicle, a pigment is insoluble in the vehicle, but instead is held in a suspension.
- Three-dimensional works of art in which images and forms are produced in relief, in intaglio, or in the round. The term refers particularly to art works created by carving or engraving a hard material, by molding or casting a malleable material (which usually then hardens), or by assembling parts to create a three-dimensional object. It is typically used to refer to large or medium-sized objects made of stone, wood, bronze, or another metal. Small objects are typically referred to as "carvings" or another appropriate term. "Sculpture" refers to works that represent tangible beings, objects, or groups of objects, or are abstract works that have defined edges and boundaries and can be measured. As three-dimensional works become more diffused in space or time, or less tangible, use appropriate specific terms, such as "mail art" or "environmental art."
- General term for any of 32 species of web-footed aquatic mammals that live chiefly in cold seas and whose body shape, round at the middle and tapered at the ends, is adapted to swift and graceful swimming. There are two types of animals often called by this term: the earless, or true, seals (family Phocidae); and the eared seals (family Otariidae), which comprise the sea lions and fur seals.
