Definition

A sector is a part or division of a larger whole, especially in the economy, society, or an area of activity. In math, it can also mean the part of a circle between two lines and the curve.

Usage & Nuances

Very common in business, government, and academic contexts: 'public sector', 'private sector', 'health sector'. It is more formal and broad than 'field' or 'area'. In math, use it specifically for a circle shape, not for any general section.
