What Do the Words occlusion, recluse, seclusion, and exclude Have in Common?
Occlusion is a descendant of the Latin verb occludere, meaning "to close up." Occludere in turn comes from the prefix ob-, here meaning "in the way," and the verb claudere, meaning "to close or shut." Occlusion is one of many English terms derived from claudere. Some others are recluse, seclusion, and exclude. An occlusion occurs when something has been closed up or blocked off. Almost all heart attacks are the result of the occlusion of a coronary (heart) artery by a blood clot. When a person's upper and lower teeth form a malocclusion, they close incorrectly or badly. An occlusion, or occluded front, happens when a fast-moving cold front overtakes a slow-moving warm front and slides underneath it, lifting the warm air and blocking its movement.
