🎤Pronunciation

🇺🇸 US/əbˈsesɪv/
🇬🇧 UK/əbˈsesɪv/

🌳Etymology

Prefixob--
Rootsess
Suffix--ive

Origin

The word derives from Latin obsessus, the past participle of obsidere, formed from ob- (before, in front of) and sedere (to sit). Originally meaning 'to besiege' or 'to sit before,' the term evolved metaphorically to describe a state of mind where thoughts persistently occupy one's attention, as if constantly watched over.

Breakdown

ob- (before, in front of) + sess- (sit, from Latin sedere) + -ive (adjective suffix forming a quality or state). The root sess reflects the Latin sedere meaning 'to sit,' while -ive transforms the past participle base into an adjective describing a persistent or habitual condition.
