sector

SEK-ter /ˈsektər/

formalacademicbusiness

A distinct part or branch of a nation's economy or a particular area of activity.

While 'area' is general, 'sector' implies a formal division within a larger economic or social system.

The story behind the word. The word comes from the Latin 'secare', meaning 'to cut'. Imagine a large pie representing the entire economy; a 'sector' is a slice cut out of that pie to be examined individually.

Word relationships

  • industry: Industry refers to a specific type of business, while sector is a broader economic category.
  • domain: Domain refers to a field of knowledge or influence, not necessarily an economic division.
  • whole: The entire economy rather than a specific division.

Commonly confused with

  • section: A section is a physical part of a whole; a sector is a conceptual or economic division.

Memory hook
