1. Focus on Related Words
To effectively learn and retain vocabulary, concentrate on words that are related or synonymous. For instance, if you're learning vocabulary related to professions, focus solely on words pertaining to various occupations or activities within the field. Avoid random learning, as studying related words enhances memory retention and makes learning easier and more cohesive.
Grouping vocabulary by theme is crucial, as related words often go hand in hand, facilitating easier memorization. When starting out, stick to simple themes such as emotions, weather, objects, time, clothing, school, etc. Set daily learning goals for yourself, both in terms of quantity and retention, and make sure to regularly review vocabulary related to the chosen theme.


2. Get yourself an illustrated dictionary
Science has proven that the human brain has a region dedicated to storing images, much like a camera. This has been demonstrated by the fact that learning through mind maps helps in quicker memorization compared to reading plain text in books. And vocabulary learning is no different; you should acquire an illustrated dictionary, as they help stimulate better retention of vocabulary.
No method makes learning vocabulary faster and more long-lasting than associating it with its visual representation. Therefore, for anyone starting to learn Korean, investing in a Korean-Korean dictionary with illustrations is advisable. Consulting a Korean-Korean dictionary will help you remember vocabulary better through visualizing the illustrations encountered during learning.


3. Learn Vocabulary in Fields You Love
It's obvious that when you're doing something you love, you're more effective than when you're doing something out of obligation. Vocabulary learning works the same way. When you have a passion for a particular field, you'll be curious about how that field uses Korean, and that curiosity will motivate you to seek answers. As a result, you'll feel enthusiastic, your brain will be more active, and you'll be more interested and able to memorize vocabulary faster.
For example, if you're passionate about soccer, sports, cooking, fashion, design, etc., look for vocabulary related to these topics. Remember, what you love is what you want to talk about and is part of who you are. If you don't know how to express them in a new language, it can make you anxious when discussing the things you love.


4. Create a Vocabulary Tape
Create your own vocabulary tape, where you read in Vietnamese first, then pause for a moment before reading in Korean. This pause allows you to mentally visualize the meaning of the Korean word. You can also download audio clips from Korean language learning websites for better pronunciation. And make sure to listen to them regularly, utilize any available time, whether on the bus, during breaks, or leisure time... Continuous listening will significantly enhance your vocabulary.
In your free time, like when walking, waiting for friends, or riding the bus, you can play the recorded vocabulary clips to listen to. Repeated listening will help you remember better. Additionally, you can listen to Korean music if you find it boring.


5. Utilize video resources
Similar to learning through images, using videos is equally effective for enhancing your Korean vocabulary. While watching a movie, make an effort to notice and jot down 5 to 10 Vietnamese words for objects whose Korean meanings you don't know, then look them up in a dictionary to memorize them. This method will help you learn vocabulary quickly. Additionally, watch Korean movies with Vietnamese subtitles, which will help you practice listening to Korean for free from native speakers while also learning vocabulary through the subtitles.
With the video method, every time you watch a movie, slow down and read along with them. Look up any unknown words in the dictionary and then continue watching the movie. Practice like this many times and regularly until you can naturally speak the words or dialogue.


6. Practice New Words While Writing Essays
When writing an essay, regardless of the topic, make an effort to incorporate the Korean vocabulary and new words you've learned into your writing. Remember, if you don't use and review the vocabulary regularly, you'll quickly forget them, rendering your learning efforts seemingly futile. Therefore, the only way to remember effectively is to practice regularly, especially through essay writing.
Writing essays and practicing using new words in Korean essays also helps you develop vocabulary arrangement and logical thinking while writing.


7. Purchase a Thesaurus
Get yourself a notebook, jot down the vocabulary you've learned or encountered somewhere, and arrange them in order of synonyms and antonyms. When practicing speaking, try to use one sentence but replace it with different words with the same meaning, this will expand your vocabulary and significantly demonstrate your proficiency in Korean.
Although sometimes you may use a word that doesn't quite fit the context of the sentence, it doesn't prevent you from using this useful book to build a rich vocabulary in Korean for yourself.


8. Practice New Words While Speaking
Every day, list 5 to 10 vocabulary words you've learned and want to use, then try to apply them in conversations whenever you practice speaking Korean. This will stimulate your interest in learning Korean vocabulary and also significantly enhance your listening and speaking skills.
While many people find Korean vocabulary challenging to memorize, applying the method of practicing new words while speaking, most people find it effective and improve their Korean vocabulary.


9. Practice New Words While Doing Grammar Exercises
Don't think that you only need to pay attention to new words when speaking or writing. When doing grammar exercises, besides remembering structures and tips for doing exercises, you should also take note of the new words you encounter. Additionally, you must maintain the habit of spending 20 to 30 minutes each day reviewing old lessons, avoiding relying on looking back only when studying. Because that period will help you quickly forget those vocabulary and make them harder to remember when studying again.
Practicing new words while doing grammar exercises is one of the methods and secrets to effectively learning vocabulary.


10. Read a Lot
No one is naturally good except through effort. And learning Korean specifically and learning languages in general require you to read a lot, to immerse yourself in that language as much as possible every day to improve your skills. In the readings, there are often words related to each other, so when you read, you can infer the meaning of other words from one word and the context.
Reading a lot not only helps improve speaking skills but also helps build a rich vocabulary. Usually, each reading will be a different topic and link together because of that, so you can use the words you've learned to guess the meanings of new words.
