Orlandi Giorgio.. On the classification of the Ng Yap dialects: some thoughts on the subgrouping of Sinitic languages. Journal of Language Relationship, 17, 1-2, 128. https://doi.org/10.31826/jlr-2019-171-212., The Ng Yap (formerly Sze Yap) dialects are routinely considered a branch of the Yue subfamily. This paper seeks to demonstrate that, contrary to this widespread opinion, these dialects show a wide range of distinctive features which, for formal purposes of language/dialect classification, may warrant their separation from the Yue subfamily. This paper also discusses the criteria which are often at the basis of language subgrouping in the field of Chinese linguistics. Nevertheless, this work should be regarded only as an attempt of stimulating a further discussion into a topic which has been overlooked for far too long.
