Proto-Mienic or Proto-Yao () is the reconstructed ancestor of the Mienic languages.
Reconstructions of Proto-Mienic (Proto-Yao) include those of Purnell (1970), L-Thongkum (1993), Ratliff (2010), and Liu (2021).
Purnell (1970) and L-Thongkum (1993) do not include any data from the divergent Biao Min and Zao Min languages. Purnell's (1970) Proto-Yao reconstruction is based on Iu Mien (Chiengrai <nowiki>[</nowiki>Chiang Rai, in Hwei Kang Pa à ¸«à ¹Âà ¸§à ¸¢à ¸Âà ¹Âà ¸²à ¸Âà ¸Âà ¸¥à ¸²], Hsing-an <nowiki>[</nowiki>Xing'an<nowiki>]</nowiki>, and Taipan [ÃÂại Bản 大æÂ¿] dialects) and Kim Mun (Haininh <nowiki>[</nowiki>Quảng Ninh<nowiki>]</nowiki> and Ling-chun <nowiki>[</nowiki>Lingchuan<nowiki>]</nowiki> dialects).
Liu's (2021) Proto-Yao reconstruction is based on data from Iu Mien (Jiangdi æ±Â庠and Miaoziyuan åºÂÃ¥ÂÂ溠dialects), Biao Mwan (Luoxiang ç½Âé¦Â), Kim Mun (Liangzi æ¢Âå and Tansan 滩æÂ£ dialects), Biao Min (Dongshan ä¸Âå±± and Shikou ç³å£ dialects), and Zao Min (Daping 大åª). More than 500 lexical items are reconstructed.
Liu (2021:78-80) gives the following consonant inventory for Proto-Mienic.
Initial consonants can be preglottalized, aspirated, or devoiced. Final consonants include /-p, -t, -k, -m, -n, -Ã Â/.
Ostapirat (2016) proposes velarized initials in Proto-Mienic, which are not reconstructed by Liu (2021), Ratliff (2010), and others. Below is a comparison of selected Proto-Mienic reconstructions with initial bilabial stops from Ostapirat (2016), Liu (2021), L-Thongkum (1993) ("Pre-Mjuenic" reconstructions), and Ratliff (2010).
Liu (2021:165) reconstructs 8 Proto-Mienic vowels.
<nowiki>*</nowiki> only occurs as part of the rimes *- and *-.
Liu (2021) reconstructs contrastive vowel length for Proto-Mienic. However, L-Thongkum (1993) and Ratliff (2010) do not reconstruct vowel length for Proto-Mienic, as they consider vowel length in synchronic Mienic languages to be later prosodic developments.
Sound correspondences among the Mienic languages from Liu (2021):
Reflexes of Proto-Mienic initials in synchronic Mienic languages are as follows (Liu 2021). Prenasalized Pre-Mienic initials are reconstructed; these developed into certain preglottalized and aspirated Proto-Mienic initials.
