[1] The concept of "interpretant" is part of Charles Sanders Peirce's "triadic" theory of the sign.
For Peirce, the interpretant is an element that allows taking a representamen for the sign of an object, and is also the "effect" of the process of semeiosis or signification.
Peirce delineates three types of interpretants: the immediate, the dynamical, and the final or normal.
"[3] An Immediate interpretant can take a variety of forms "it may be a quality of feeling, more or less vague, or an idea of an effort or experience awaked by the air of previous experience or it may be the idea of a form or anything of a general type".
is the "direct effect actually produced by a Sign upon an Interpreter of it".
