grupusculismo 18
Although debatable, the neologism can be interpreted as the tendency of some groupings which at first share a common idea to disintegrate, to separate into small groups by personal ambitions, difference of nuances in ideology or by trifles that prevent the formation of a block of weight in their field. It is clearly derogatory, and is formed by small groups ("small group, especially of people") the suffix -ism (in its double sense of "doctrine" and "attitude"). See isms.
