From Generative Anthropology

A Sign is a sound-image affixed or conferred meaning, in reference to an object which may have no correlation to the form of the sound-image, especially in declarative signing: A la Saussure, the sign is split into two parts: the signifier, which is physical, and the sound-image; the signified, which is immaterial, and the intended meaning pointed to by the signifier. Correlation between a sound-image and its meaning relies on the ability to trace the intention of another language user, as well as faith: that they mean what they say, and mutually that you sufficiently understand their intended meaning.
