Language is a code. Particular sign is constitued by a relationship between an engram (potential form) and hidden coded ?meaning?. Actual Meaning (or the multiplicity of Actual Meanings) can be observed in Discourse. It must be remarqued that we distinguish also Coded Distribution (Combinability, Distribution Class) and Actual Distribution (in a discourse or in a corpus). Our documentation has permited to specify, adjust and amend what our predecessors said about Linguistic Fields (paradigmatical ? unidimensional, bidimensional or arborescent) or several kinds of Developped Fields), composed or monomorphons, of developped units, of polysynthetic units or of syntetic complex onomatological groups (cf. it. far un salto, esp. dar saltos, fr. esquisser un sourire, angl. have a shave, have a smoke ... vs. to smoke, to shave ...). Etymological units occur within very diversified, coded or not coded structure.
