Esthesic and poietic
Like 'emic' and 'etic', both words appear to be derived from a suffix, -poietic (from Greek: ποιητικός "creative") meaning productive or formative and -esthesic (from αἴσθησις "sense") being receptive or perceptive, in relation to the neutral level. The neutral level is the "trace" left behind, the physical or material creation of esthesic and poietic processes.
Thus, "a symbolic form... is not some 'intermediary' in a process of 'communication' that transmits the meaning intended by the author to the audience; it is instead the result of a complex process of creation (the poietic process) that has to do with the form as well as the content of the work; it is also the point of departure for a complex process of reception (the esthesic process) that reconstructs a 'message.'" (Nattiez 1990, p. 17)
