means To move on foot faster than a walk, with a stride that briefly leaves the ground entirely — or, by extension, to operate, manage, or flow continuously, as a business, a machine, or a river runs.

from From Old English 'rinnan' and 'ærnan,' part of a tangled family of Germanic verbs for flowing and racing — kin to Old Norse 'rinna' and Dutch 'rennen.' The two old roots merged over time into one verb that now covers everything from sprinting to a nose running to a factory running round the clock, which is why 'run' has more dictionary senses than almost any other English word — it absorbed centuries of motion into a single syllable.
