WebGrassmann introduced an extensive formation as the totality of elements obtained by variation of the generating element [HGW11, 28]. He then defined an extensive magnitude as the class of extensive forms that are generated according to the same law by means of equal variations [Grassmann 1995, 47], in other words, the class of all extensive ...

Grassmann's law, named after its discoverer Hermann Grassmann, is a dissimilatory phonological process in Ancient Greek and Sanskrit which states that if an aspirated consonant is followed by another aspirated consonant in the next syllable, the first one loses the aspiration.
