ENVULSIONAR non-existent verb in Spanish . Perhaps it meant EMULSIONAR, to mix two immiscible elements, at least one of them fat, to form a homogeneous mixture, as with oil and water in butter. Other possibilities are TO EVOLVE, to become something better, your reverse INVOLUTION, CONVULSIONAR have or produce remezones, and, less likely, REVOLUTION, produce a sudden change (of thought, fashion or other type), and eventually violent, in society.
