Etymology: "Obsessively" is a straightforward formation: the adjective "obsessive" with the adverbial suffix "-ly" attached. The adjective itself is built from "obsess," a verb that comes from Latin "obsidere," meaning to besiege or sit down in front of something, with the sense of a blockade that holds a place until it gives way. That physical image of being hemmed in and pressed upon is what the modern psychological sense grew out of. The adjective "obsessive" carries the suffix "-ive," which comes through Old French "-if" from Latin "-īvus," a marker of tendency or quality. English took it in and attached it to "obsess," giving a word meaning inclined to obsess. The "-ly" at the end is the Old English "-līċe," which turned adjectives into adverbs describing manner. Adding it to "obsessive" produces "obsessively," describing an action carried out in that compulsive, fixated way.
