noun

The study of shapes, spaces, and how parts are connected. In mathematics, it looks at what stays the same when shapes are stretched or bent.

  • Topology studies how spaces are connected.
  • She is taking a course in topology.
  • The shape changed, but the topology stayed the same.

Adinary Nuance

Topology is more specific than 'geometry'. Geometry studies size, angles, and exact shape, while topology studies connection and structure. It is also more technical than 'shape' or 'layout', which are used in everyday English. In academic writing, topology usually means the mathematical field, not a general description of form.
