Word History

Etymology

Middle English, in be obscessed "be tormented by (the Devil, an evil spirit)," borrowed from Latin obsessus, past participle of obsidēre "to sit so as to occupy a position, occupy, frequent, besiege, blockade, beset, assail" (Late Latin, "[of a demon] to possess"), from ob- "toward, facing, against" + sedēre "to sit, be seated" — more at ob-, sit entry 1

Note: This verb in its participle form obsessed is fairly common in early Modern English as a metaphorical extension of its Latin etymon in the sense "besiege, beset," the torment attributed to the Devil being compared to the besieging of a fortress. The same applies to the associated noun obsession. With these meanings the word is sometimes accompanied by its synonyms possessed and possession. From about 1660 to the early nineteenth century obsess and obsession are exceedingly rare in English text outside of dictionaries. They then begin to revive, but without any religious connotation, perhaps stimulated by parallel use in French of obséder and obsession.
