Abstract: A method, called Interwriting, that builds one or more independent texts within a bigger normal text, referred to as ordinary text, by selectively highlighting or otherwise signalizing some of the words in the ordinary text. Although recycling some of the same words, the ordinary text and the signalized text, each communicates its own distinctive message without disrupting one another's content. A signalized text conveys its own distinct message only when read separately from the ordinary text that houses it.
