obsesionado
/obsesjoˈnado/ · B1 · adj
obsessed
obsesionado = obsesión + -ado, the Spanish -ed ending: obsess-ed
Spanish -ado works like English -ed, so obsesionado is simply obsessed. Both come from Latin obsidere, to besiege (ob- against + sedere to sit). An obsession is a thought that sits outside your mind's walls and won't leave.
