English neologism well defined by comrades Katiana and Manuel, derived from gentry, aristocracy, haute bourgeoisie, people of high social status, taken from the realm of urbanism and sociology. Process of residential elitization or urban requalification by the progressive penetration into a neighborhood or urban area of people with a social status higher than that of the residents. This term has slept for some time at the door of the RAE, as its director Santiago Muñoz Machado says and finally they have opened the door as to many other words.
