Etymology: "Occluded" is the past participle of "occlude," which English borrowed from Latin "occludere," a compound of "ob" ("before" or "against") and "claudere" ("to shut"). The Latin verb pictured something being shut off or closed against, and that sense of blocking passage carried into English. Closing a door or a gap is the physical root, and everything hidden or obstructed follows from that image. The adjective applies the same logic to perception: something occluded is shut away from view, with another object or a barrier standing in front of it. The same root gives "conclude" and "include" (from "claudere" through its Latin relatives), which share the idea of closing something in or off. Astronomers and medical professionals later adopted "occlude" for eclipses and blocked vessels, extending the old image of a shut door to celestial bodies and arteries.
