Does not exist in Spanish. Perhaps a poetic form for whiteness; or a composite for "pale face"; may also appoint any feature of the great crested grebe, because in Arabic his name sounds like "albatoza" (as the ship, but I don't think it has to do with the nautical); If it comes from the catalan, it would be a synonym of "naivety" (by albat); and suspicious of albato esperanto ("shock", "blow") because he never contributed to the Spanish.
* Only one "like" per meaning and day, the more "likes" the meaning will appear higher in the list
