ABSTRACT
Following the publication of Meillet's Introduction in 1937, Indo-Europeanists agree in general on the phonological system of the protolanguage. It has been determined by application of the comparative method, the results of which are treated phonemically. The phonemes are also examined for their morphological roles, especially in verbal roots and bases. In contrast, the system given in the older standard handbooks is based essentially on phonetic analysis, extended by the procedures that Brugmann labeled purely systematic (1897: ix).
