Almost a century ago, in the introduction to his Dictionary, Jäschke said that the graphic symbol འ, now sometimes called ''a-chung'', represented ''the vowel absolute, the pure vocalic note, freed altogether from any presence of a consonant'' (xiv), whether it was used before symbols representing vowels or stops or after symbols representing consonants. The nasal reflexes of a-chung before stops, found ''throughout Khams, and in the rest of Tibet at least in compound words'' (xv) he attributed to a carelessness in closing the nasal passage. Clauson and Yoshitake (1929), similarly, interpreted preconsonantal a-chung as ''a very short vowel, like the Hebrew sh'va'', and suggested that ''in practice, it will be found very difficult to pronounce this sound without some of the breath escaping through the nose and giving a nasal element to it, particularly if the monosyllable in which it occurs is in the middle, and not at the beginning of the sentence, and if care is taken to avoid introducing the glottal stop'' (p. 849). |
