The term 'vulgarization' is built upon the Latin root vulgus, meaning "the common people, the multitude." From this root, the adjective 'vulgar' originally meant "pertaining to the common people," carrying a neutral sense of "ordinary" before acquiring its modern pejorative connotations of coarseness and lack of refinement. The suffix '-ization', a productive English formative derived ultimately from Greek '-izein' via Latin and French, denotes the process of causing or making. Therefore, the literal morphemic logic of 'vulgarization' is "the process of making (something) common or of the people." Over time, this evolved into the dual modern abstract meanings: the often-negative process of debasing sophistication to appeal to popular taste, and the neutral process of popularizing or disseminating knowledge to the general public.
