Synonym discussion
Sense: noun/1
Crater, hole, pit, cavity, and depression all describe empty spaces or hollows, but they differ in cause, size, and location. A crater is a large, bowl-shaped depression formed by volcanic activity, meteorite impact, or explosion — it is always open at the top and usually found outdoors. A hole is the most general word: any opening or gap in a surface. A pit is a deep hole in the ground, often dug by people (e.g., a mine pit or a trap pit). A cavity is an enclosed hollow space inside a solid object, such as a cavity in a tooth or inside a wall. A depression is a formal term for any sunken area, which can range from a small dent to a large basin. For example: 'The hikers stood at the crater's edge,' but 'The dentist filled the cavity in my tooth.' To describe bomb damage, crater is the precise term; for a man-made excavation, use pit.

Etymology
Crater entered English in the early 1600s from Latin 'crater', meaning a bowl-shaped mixing vessel. The Latin word itself came from Greek 'krater' (κρατήρ), a large wide-mouthed bowl used in ancient times for mixing wine and water. The geological meaning arose in the 1700s when scientists noticed that the bowl-shaped openings of volcanoes resembled the shape of these ancient vessels.
