Initial clusters

In 14 compilations 112 different initial clusters have been found. Comparative examination of catalogue membership reveals unanimous agreement on 22 clusters and near unanimity on 8 others. Beyond these there is frequent disagreement, in relatively minor degree accounted for by apparent oversight and limitation of source, and in relatively major degree due, first, to differing phonetic and dialectal assumptions resulting primarily in differential appearance of clusters ending in /j/, and second, to inconsistent appearance of variously qualified clusters. In the comparative membership support is seen for the concept that phoneme combination is a matter of greater or lesser probability rather than of possible vs. impossible.
