Definition

Circulation is the movement of something around a system or through a group of people.

Circulation refers to how something moves continuously from place to place, often in a repeated cycle. It can describe the flow of blood through the body, the movement of air or water, or the way information and publications are distributed among people. It is also used for how easily people or vehicles can move through an area.

Examples

  • Regular breaks help maintain circulation when I’m stuck at my desk for hours.
  • The architect improved circulation by widening the hallway and removing an unnecessary partition.
  • Rumors spread fast on campus once they enter circulation.
  • The magazine expanded its circulation by partnering with independent bookstores.
  • If you open the windows on both sides, you’ll get better air circulation in the studio.

Common mistake

Learners often confuse circulation with cycle, but circulation emphasizes movement through a system or among people rather than just repeating stages over time.
