Gain progresio informatibo graduala, hásiz ti informazio thematikoena (tipikoki sujetua) eta bukátuz an rhematikoena (tipikoki an osagarriak)

Genioen herenegun ze esango genuen zerbait gehiago gain Firbas-en teoria funtzionala, eta horrá ondorengo aipua ti bere artikulua titúlatzen "On the concept of communicative dynamism in the theory of functional sentence perspective" (1971):

Sentence linearity is an indisputable fact. It makes the speaker/writer arrange the linguistic elements in a linear sequence, in a line, and develop the discourse step by step. I believe to be right in assuming that the most natural way of such gradual development is to begin at the beginning and proceed in steady progression, by degrees, towards the fulfilment of the communicative purpose of the discourse. If this assumption is correct, then a sequence showing a gradual rise in degrees of CD (i.e. starting with the lowest degree and gradually passing on to the highest degree) can be regarded as displaying the basic distribution of CD. [Firbas, 1971:138]

Hori da planteaméndu orokorra te Firbas: informazioa joango litzake progrésatzen gradualki, hásiz ti informazio thematikoena (tipikoki sujetua) eta bukátuz an parte rhematikoena (tipikoki an osagarriak).
