Glottalic theory
The glottalic theory is that Proto-Indo-European had ejective or otherwise non-pulmonic stops, , instead of the plain voiced ones, as hypothesized by the usual Proto-Indo-European phonological reconstructions. A forerunner of the theory was proposed by the Danish linguist Holger Pedersen in 1951, but he did not involve glottalized sounds.
Alternation (linguistics)
In linguistics, an alternation is the phenomenon of a morpheme exhibiting variation in its phonological realization. Each of the various realizations is called an alternant. The variation may be conditioned by the phonological, morphological, and/or syntactic environment in which the morpheme finds itself. Alternations provide linguists with data that allow them to determine the allophones and allomorphs of a language's phonemes and morphemes and to develop analyses determining the distribution of those allophones and allomorphs.
