 The second type of interpretant that any sign must have is the dynamic interpretant. This is our understanding of the sign/dynamic object relationship at some actual instance in the chain of signs. Peirce describes the dynamic interpretant as the “effect actually produced on the mind” (CP8 .343 1908), or as the “actual effect which the sign, as a sign, really determines” (CP4 .536 1906). The dynamic interpretant, then, is the understanding we reach, or which the sign determines, at any particular semiotic stage.
