Eastern Han Chinese syllables consisted of an initial consonant, optional medial
glides, a vowel and an optional coda.
Initial consonants The consonant clusters postulated for Old Chinese had generally disappeared by the Eastern Han period. One of the major changes between Old Chinese and Middle Chinese was palatalization of initial
dental stops and (in some environments)
velar stops, merging to form a new series of palatal initials. Several Eastern Han varieties show either or both of these palatalizations. However,
Proto-Min, which branched off during the Han period, has palatalized velars but not dentals. The retroflex stops and sibilants of Middle Chinese are not distinguished from plain stops and sibilants in the Eastern Han data. There is some uncertainty whether the Middle Chinese initials , and can all be derived from a single Old Chinese initial *, or whether an additional fricative initial * or * must be reconstructed. Most Eastern Han dialects have a single initial * in such words, but some of them distinguish * and *. Some Eastern Han dialects show evidence of the voiceless sonorant initials postulated for Old Chinese, but they had disappeared by the Eastern Han period in most areas. The Old Chinese voiceless lateral and nasal initials yielded a * initial in eastern dialects and * in western ones. By the Eastern Han, the Old Chinese voiced lateral had also evolved to * or *, depending on syllable type. The gap was filled by Old Chinese *, which yielded Eastern Han * and Middle Chinese . In some Eastern Han dialects, this initial may have been a lateral
tap or flap.
Medial glides Most modern reconstructions of Old Chinese distinguish
labiovelar and labiolaryngeal initials from the velar and
laryngeal series. However, the two series are not separated in Eastern Han glosses, suggesting that Eastern Han Chinese had a * medial like Middle Chinese. Moreover, this medial also occurs after other initials, including syllables with Old Chinese * and * before acute codas (*, * and *), which had broken to * and * respectively. Most OC reconstructions include a medial * to account for Middle Chinese retroflex initials, division-II finals and some
chongniu finals, and this seems to have still been a distinct phoneme in the Eastern Han period. Since the pioneering work of
Bernhard Karlgren, it has been common to project the palatal medial of Middle Chinese division-III syllables back to an Old Chinese medial *, but this has been challenged by several authors, partly because Eastern Han Buddhist transcriptions use such syllables for foreign words lacking any palatal element. However, Coblin points out that this practice continued into the Tang period, for which a medial is generally accepted. Scholars agree that the difference reflects a real phonological distinction, but there have been a range of proposals for its realization in early periods. The distinction is variously described in Eastern Han commentaries: • He Xiu (; mid 2nd century) describes syllables that gave rise to Middle Chinese as 'outside and shallow' ( ), while others are said to be 'inside and deep' ( ). •
Gao You (early 3rd century) describes the former as 'urgent breath' ( ) and the latter as 'slack breath' ( ).
Pan Wuyun and
Zhengzhang Shangfang interpreted this as a
vowel length distinction, but a more literal reading suggests a
tenseness contrast.
Vowels Most recent reconstructions of Old Chinese identify six vowels, *, *, *, *, * and *. Eastern Han rhyming practice indicates that some of the changes found in Middle Chinese had already occurred: • The vowels * and * had merged before *, * and *. • The finals * and * had merged (Middle Chinese ). • The following splits and mergers of finals had occurred: The Middle Chinese finals and occur with finals of all kinds, while occurs only after plain sibilant and palatal initials, with no known conditioning factor.
Codas The Middle Chinese codas , , , and are projected back onto Eastern Han Chinese. The Middle Chinese coda also appears to reflect in most cases, but in some cases reflects vocalic codas in some Eastern Han varieties.
Baxter and
Sagart argue that these words had a coda in Old Chinese, which became in
Shandong and adjacent areas, and elsewhere. Middle Chinese syllables with vocalic or nasal codas fell into three
tonal categories, traditionally known as even, rising and departing tones, with syllables having stop codas assigned to a fourth "
entering tone" category.
André-Georges Haudricourt suggested that the Middle Chinese departing tone derived from an Old Chinese final , later weakening to . Several Buddhist transcriptions indicate that was still present in the Eastern Han period in words derived from Old Chinese . Other departing tone syllables may have become by the Eastern Han period, as suggested by a slight preference to use them to transcribe Indic long vowels. Based on Haudricourt's analysis of Vietnamese tones,
Edwin Pulleyblank suggested that the Middle Chinese rising tone derived from Old Chinese . Syllables in this category were avoided when transcribing long vowels in the Eastern Han period, suggesting that they were shorter, possibly reflecting this final glottal stop. == Grammar ==
