Easy Languages are standard language varieties that have been contentually, lexically and structurally adapted to make them more readable and understandable. All Easy Languages consist of verbal signs that have been made “easy”, i.e., linguistically or cognitively accessible for a new target group – tailored to meet this group’s lifelong or more temporary specific language- and communication-related needs. Making texts more comprehensible involves a process that can be considered translating. Easy Language adaptations are, in fact, investigated within translation studies, as well as other disciplines, and can be approached, as here, as a combination of intralingual-interlingual-intersemiotic translation activities. Within translation semiotics, adaptations into Easy Language can be equated with sign translation – semiosis, or sign action and sign interpretation. As both approaches are based on Peircean semiotics, we must examine the theoretical, semiotic ground for the adaptations to be able to find both the potential and possible outcomes of adopting Peirce’s views as a paradigm for future research on sign tailoring. Perceiving feeling, skill and knowledge here as an outgrowth of Peirce’s triadic thinking makes them apposite for highlighting Peirce’s universal categories and exemplifying the empowering agency of the signs in the life and world of the subject.
