Is this a "real" word? Or did somebody just think it was neat to combine "dispose" and "phobia" in this way? What, have we all become 10th-graders now? I mean, does anyone even bother anymore trying to find out if there is an applicable Greek stem that would go with -phobia here? (Qroqqa, can you help? Would apobolophobia work? In any case, it's much nicer than "disposophobia" *shudder*.)
If I were running the world, everyone would have to go through a couple of years of Greek and Latin, with some Hebrew, Sanskrit and Taoist/Confucian Chinese thrown in as well. Oh, and a bit of Quranic Arabic wouldn't hurt either. And maybe some Swahili, too. Not, of course, that I am afraid to throw away any of the great, culture-defining languages of the world.
Disposophobia means compulsive hoarding (or pathological hoarding). It is the excessive acquisition of possessions (and failure to use or discard them), even if the items are worthless, hazardous, or unsanitary. Compulsive hoarding impairs mobility and interferes with basic activities, including cooking, cleaning, hygiene, sanitation, and sleeping.
