Glottogonic

Indirectly, this echoes the Neogrammarians, who, upon rejection of the glottogonic separation of stages of language held by their predecessors (cf. 4.10., 5.) affirmed that in the IE languages, "die Schöpfung neuen Stoffes niemals ganz aufgehört hat" ["the development of new grammatical material had never stopped"](Paul 1920 [1898], 175).

There are now quite a few glottogonic theories, some of which are also concerned with the origin of words as, for example, the one that argues that original words are connected with phonosymbolism, […]

Johannes Schmidt was later to argue that it was a natural step for the generation of scholars following Schleicher to discard the glottogonic reconstructions.

The glottogonic view was perhaps the principal difference between the Neogrammarians and their predecessors.
