11. Summary of the new findings of the thesis:

Thesis reviewed different approaches to antonyms in general and Vietnamese antonyms in particular. The thesis focused on researching the system of the Vietnamese antonyms in term of morphology, semantics, and pragmatics.

The Vietnamese antonymy was distinguished from other semantic relationships (hyponymy, meronymy, troponymy, semantic role, causonymy, polysemy, and synonymy) through the important properties such as substitutability, transitivity, hierarchy, co-occurrence, and homomorphism, etc.

The Vietnamese antonyms were identified by a variety of criteria belonging to groups like logical, phonetics, semantics, grammar and pragmatics.

The Vietnamese antonyms are lexical units whose parts of speech, the number of constituents, the mechanics of morphology, the word order, and the origin of words are similar.

The semantic structure of the Vietnamese antonym system could be visualized through the important tool of concepts such as antonyms, antonymous word pairs, antonymous pairs, antonymous clusters, and antonymous chains.

Vietnamese antonyms can co-occur in the contexts of actual usage called lexicogrammar patterns. These lexicogrammar patterns in which antonyms co-occurred were fully and deeply tested in Vietnamese idioms and proverbs, and Truyen Kieu. We also suggested a new taxonomy of Vietnamese antonyms in terms of the discourse functions based on the co-occurrence contexts.

12. Practical applicability, if any:

The Thesis helps lexicographer compile a Vietnamese antonym dictionary quickly and efficiently; improve Vietnamese dictionaries by adding up semantic relationships.

The Thesis also provides a solution from the linguistic perspective for interdisciplinary and modern researching of language, such as the building of the Vietnamese corpus (Vietnamese WordNet...), detecting words automatically, language education, etc.

13. Further research directions, if any:

To study Vietnamese antonyms in quantitative and comparative approaches.
