Definition

A large, bowl-shaped hollow in the ground. Such features occur at volcanic peaks, created by eruptions, and can also be formed by meteorite strikes or bomb explosions.

Example

Ari peered over the edge of the volcanic crater and watched the smoke rise.

collocation: volcanic crater

A huge crater formed in the road after the gas pipeline exploded.

Common collocations
  • volcanic crater
  • impact crater
  • bomb crater
  • crater rim
  • crater floor
  • deep crater
Synonyms
  • hole

    General term for any opening; crater is more specific to large, round depressions from volcanic or impact causes.

  • pit

    A deep hole in the ground, often man-made (e.g., a mine pit), whereas a crater is formed by natural or explosive force.

  • depression

    A sunken area on a surface; more formal and less specific than crater.

  • cavity

    An enclosed hollow space inside something; crater is an open depression on the surface, often larger.

Usage Note

When referring to bomb damage, crater often pairs with compound nouns like bomb crater or shell crater. For volcanoes, the phrase volcanic crater is standard.

Common Mistakes

The dentist filled the crater in my tooth.
The dentist filled the cavity in my tooth.
A 'crater' is a large outdoor depression, not a small hole inside a tooth; 'cavity' is the correct dental term.

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

GreekLatinFrenchEnglish

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.
