“Run” can mean move quickly on foot, operate, manage, flow, or continue for a period of time. Its meaning depends on the words around it and the situation, so learning common patterns is more useful than looking for one definition that fits every sentence.

Movement and flow

The most familiar meaning is moving quickly on foot: Maya runs in the park every morning. The verb can also describe something moving or flowing, often without control: Water ran under the door during the storm. In this use, the subject is the thing that moves or flows.
