The action or process of spreading widely in different directions; a scattering or dispersal.
From disspread (dis- + spread) + -ing (gerund/participle suffix). The -ing form converts the verb into a noun describing the ongoing action or process itself.
The -ing suffix is one of English's superpowers—it lets any verb become a noun describing an action, which is why you can talk about 'spreading,' 'disspreading,' 'respread,' etc., all as distinct concepts.
