Editors Fuchs, Toda and Zygis describe in their introduction that a complete understanding of obstruent sounds would require experts from fields as far ranging as phonology, dentistry and aerodynamics.
The primary focus of this paper is LR's ongoing convergence to a ser to distinguishing phonetic and phonological elements shared between the two source languages, including: final obstruent devoicing, glottalization, and final consonant deletion.
If it were the case that obstruent + fricative sequences were universally less marked than obstruent + stop sequences, then we could have an explanation for the selection of [a:rdsag[?
Examples of complete obstruent devoicing are plenty in the case of changes like in OE burz > burh 'town' or PGmc hlass > hlaf 'loaf', etc.
The phonological facts pertinent to RS include the following (6): (1) the Italian syllable consists of a nucleus, optional onset, and optional coda; (2) an onset cluster may be two or three consonants; (3) a two-consonant cluster consists of an obstruent followed by a liquid or a sibilant followed by a stop (sdegno); (4) a sibilant preceding an obstruent and a liquid forms a triple cluster (stretto); (5) gemination occurs only intervocalically (dramma) or following a vowel and preceding a liquid (dottrina); (6) a coda can have a maximal cluster of two consonants with first being a liquid or a nasal; and (7) a CV structure is favored.
Page after page of obstruent data and marching columns of Pearson correlations in the new book The Bell Curve by Murray and Herrnstein, which holds that success in life is mainly determined by inherited IQ and that statistically significant differences in inherited intellect exist among the races, imply that the issues at play in the IQ dispute are so sophisticated only readers of high intelligence can grasp them.
