11. Summary of the new findings of the thesis:

- The thesis identifies 794 typonyms of villages in Northern Delta that have both Vietnamese and corresponding Sino-Vietnamese names. Based on historical-comparative method, the origin of some toponyms was phonologically reconstructed. The results show that there are toponyms which reflect the language contact of Vietnamese and other Austroasiatic, Austronesian and Tai-Kadai languages. Among them, many toponyms was analysed to be originated from the languages of minorities ethnic in Vietnam.

- In terms of grammar: both Vietnamese and Sino-Vietnamese names have complex structure with general name and proper name. The general name of both kinds have simple form. The proper name of Vietnamese is simple while that of Sino-Vietnamese is compound.

-  In terms of semantics: Vietnamese names do not usually have clear meaning. By and large, it is easier to identify the meaning of Sino-Vietnamese names but the correlation between characters and pronunciation should be well aware.

- In terms of the relationship between Vietnamese and Sino-Vietnamese names: phonetic relationship is significantly more dominant than semantic relationship.

- The findings of this study indicate that the process of converting Vietnamese villages names into Sino-Vietnamese mainly focuses on phonetic features. Semantic features are less emphasized. From the phonetic perspective, the integration of Vietnamese words into Sino-Vietnamese relfects the following rules. First, there are two main ways of changing Vietnamese names into Sino-Vietnamese: conserving pronunciation and correspondence pronunciation. Second, with regard to correspondence pronunciation, both syllables and/or one of the two syllables of Sino-Vietnamese names reflect pronunciation correlation. Third, Sino-Vietnamese and Vietnamese syllables which are in the phonetic relationship mostly have identical head vowels and corresponding rhyme. By and large, pronunciation correspondence of geographical names of villages in Northern Delta does not only provide knowledge of the process of changing village names in specific, geographical names in Vietnam in general into Sino-Vietnamese but is also an evidence of changes in Vietnamese pronunciation over time.
