diskonigi

Three pieces, and this one really does come apart. Dis- is the prefix for scattering in all directions - disdoni to distribute, disiri to disperse, disrompi to smash to bits. Koni is to know in the sense of being acquainted with something. -ig- makes a causative: to cause the state named by the root. Put them together and diskonigi is to cause something to be known in all directions, which is a rather better description of publicity than the English word manages.

Note where the -ig- sits, because it is doing real work.Koni is what you do; konigi is to make something known to somebody; diskonigi is to make it known everywhere. The igi and iĝi article is the place to get this straight, and the short version is that -ig- pushes the action outwards onto an object while -iĝ- turns it inwards: diskoniĝi is what the news itself does when it gets around, with nobody pushing. La novaĵo diskoniĝis - the news spread. Ni diskonigis la novaĵon - we spread it.

Against the neighbours. Sciigi is to inform, and it points at a particular person: you sciigas somebody of something. Anonci is to announce, a single formal act at a moment in time. Eldoni is to publish in the publisher's sense, to issue a book or a paper. Diskonigi is broader and slower than any of them: it is the campaign rather than the announcement, which is why it is the verb the Esperanto movement uses about itself more than almost any other. Diskonigado is the ongoing effort, and it turns up in association minutes constantly.
