Language is a code. Particular sign is represented by the relationship between the engram (potential form) and the hidden, encoded meaning. The Actual Meaning (or the multiplicity of Actual Meanings) can be observed in the Discourse. It is necessary to say that we also distinguish the Coded Distribution (Combinability, Distribution Class) and the Actual Distribution (in a discourse or in a corpus). Our documentation has made it possible for us to specify, adjust and amend what our predecessors said about Linguistic Fields (paradigmatic, one-dimensional, bi-dimensional or arborescent or several kinds of Developed Fields, composed or homomorphous, of developed units, polysynthetic units or synthetic complex onomatological groups (e.g. It. far un salto, Sp. dar saltos, Fr. esquisser un sourire, Eng. have a shave, have a smoke ... vs. to smoke, to shave...). Etymological units occur within very diversified, coded or not coded structures.
