(Nguyễn Du, Truyện Kiều)

2. Lesson on "The Development of Vocabulary" (continued) number 5
A. KEY CONCEPTS
I. Creating New Vocabulary
1. Recently, new words have been formed based on the following terms: telephone, economy, mobile, ownership, knowledge, special zones, intelligence. Please explain the meanings of these new terms.
Recently, new terms have emerged from words such as telephone, economy, mobile, ownership, knowledge, special zones, and intelligence: intellectual property, knowledge economy, economic zones, mobile phone.
Mobile phone refers to a wireless device that transmits voice over a distance, not fixed to one location, used within the coverage area of a cellular provider.
Intellectual property refers to the legal rights over products created through intellectual efforts, protected by laws such as copyright, patents, and inventions.
Market economy is an economic system primarily focused on the production, distribution, and circulation of products with high knowledge content.
Special economic zones are areas designated to attract foreign investment and technology, with preferential policies compared to other regions.
Knowledge economy: an economic system that relies heavily on producing, circulating, and distributing products with high knowledge content.
2. In Vietnamese, there are words formed using the pattern X + tặc. Find examples of such words. New terms following the pattern + tặc include: skyjacker, pirate, wood thief, hacker...
II. Borrowing Vocabulary from Foreign Languages
Question 1. Identify the Chinese-Vietnamese terms in the two excerpts below:
a. The spring day of the third month, the ritual is tomb sweeping and the festival is walking in the fields. From near and far, the crowd gathers for a feast, Sisters prepare for a spring outing. The noble scholars and beautiful women stroll together, horses and carriages flow like water, clothing sharp as a needle.
(Nguyễn Du, Truyện Kiều)
b. The fateful soul of this unfortunate one, abandoned by spouse and children, bound by destiny, suffering from disgrace, the river god, all-powerful, please bear witness. If I remain pure and faithful, as a lady, I pledge to remain loyal. Entering the river, I will become a jewel of Mị Nương; descending to earth, I will be a blade of Ngu Mĩ grass. If I were to deceive my husband or betray my children, let me be the prey for fish and shrimp, the food for vultures and crows, enduring all the scorn of people.
(Nguyễn Dữ, Chuyện người con gái Nam Xương)
Chinese-Vietnamese terms:
a. thanh minh, tiết, lễ, tảo mộ, đạp thanh, yến anh, bộ hành, xuân, tài tử, giai nhân; bạc mệnh, duyên, phận, thần, linh, chứng giám, thiếp, đoan trang, tiết, trinh bạch, ngọc.
b. bạc mệnh, duyên phận, thần, linh, chứng giám, thiếp, đoan trang, tiết, trinh bạch, ngọc, Mị Nương, Ngu mĩ, nhược.
Question 2. What terms does Vietnamese use to describe the following concepts?
a. A disease that causes the loss of immunity and leads to death.
b. A systematic study of the conditions for goods consumption (such as research on customer needs, preferences…). Where do these terms come from?
a. AIDS: A disease that causes the loss of immunity, leading to death.
b. Marketing: Systematic research on the conditions for goods consumption, including studying customer needs, preferences, etc. These terms originate from foreign languages. As society develops in all aspects and international exchange continues to expand, when new concepts emerge and there are no corresponding terms in the native language, borrowing the original terms from foreign languages is one of the most effective ways to express them. This method fits well with the context of current international exchanges.
Question 3. Remember
Creating new words to expand the vocabulary is one way to develop the Vietnamese language.
Borrowing words from foreign languages is also a way to develop the Vietnamese vocabulary. The most important foreign loanwords in Vietnamese are those borrowed from Chinese.
B. EXERCISES AND SOLUTIONS

Question 4: Briefly describe the ways vocabulary can develop and discuss whether the vocabulary of a language can remain unchanged. Answer: In my opinion, vocabulary development occurs mainly through two methods: by expanding the meanings of existing words and by increasing the number of words. Expanding meanings involves deriving new uses from original terms, while increasing vocabulary may involve creating new words or borrowing terms from foreign languages.
Vocabulary always changes to meet the needs of social communication today.

Vocabulary can grow in both meaning and in the number of words.
Two main ways vocabulary expands are by creating new words and borrowing terms from other languages.
As a result, a language's vocabulary must evolve alongside societal and global progress. Without growth in vocabulary, a language would fail to meet the communication and cognitive needs of its speakers.
