This article seeks to define what is semiotic and what is Semiotics. Provided first is a brief presentation of various perspectives of Semiotics. Pursuant to this, we will seek to uncover Semiotics’ particulars by evaluating various approaches. We will commence by framing the definitions of the word “Semiotic” to consider then Semiotics via eight particular anthropic – human-related – levels. This partition, derived by the author from a Rastier typology, defines the following levels: noumenophysical, phenophysical, semiotic, representational (“mental images” and (...) concepts), sens (physical), felt (affects), cognitive other and transcendental. From here, we will consider the place of Semiotics among disciplines. Finally, the text presents a typology of relationship between disciplines, including semiotics: anadisciplinarity, disciplinarity, valodisciplinarity, intradisciplinary (such as intertheoricity), multidisciplinary, interdisciplinary, transdisciplinary, metadisciplinarity).
