Korean and English belong to completely different language families, so there are very few words that sound similar between the two.

When you learn Spanish or French, you get a lot of “free” words that sound like English.

In Korean, you have to build your vocabulary from scratch.

Staring at a long list of words and trying to force them into your brain isn’t going to work.

Instead, you need to use strategies that help your brain store information long-term.

Here are my top methods that I recommend for memorizing Korean vocabulary effectively:

Use spaced repetition systems (SRS)

The absolute best way to memorize anything is through a method called Spaced Repetition.

What’s Spaced Repetition?

When you learn a new word, your brain will naturally forget it within a few days. Spaced repetition works by testing you on that word right before you’re about to forget it.

Every time you successfully remember the word, the gap between reviews gets longer. You might review a word after 1 day, then 3 days, then a week, and eventually, a month.

You don’t need to do this math yourself. There are plenty of free apps that use this algorithm for you.

• Anki (Highly recommended and incredibly customizable)
• Memrise
• Quizlet (Using the “Learn” feature)

Learn words in context (not isolated lists)

A massive mistake beginners make is trying to memorize single words in a vacuum.

If you just memorize that 사과 (sa-gwa) means “apple”, your brain has no anchor for that word. It has nothing to connect it to.

Instead, you should practice what language experts call “sentence mining”. This simply means learning new words inside of full sentences.

When you learn a word in a sentence, you learn the grammar, the correct particles, and the natural flow of the language all at once.

Group words by their Hanja roots

Did you know that over 60% of the Korean vocabulary comes from Chinese characters?

These are called Hanja (한자). While you absolutely don’t need to learn how to write the complex Chinese characters, learning the basic Korean sounds associated with these roots is like a superpower for your vocabulary.

When you learn one root word, you can instantly guess the meaning of dozens of other words.

For example, the Hanja root 학 (hak) means “learning” or “school”. Look at how many words use this root:

Once you know that 학 means learning, it becomes incredibly easy to group these words together in your brain.

Create fun mnemonics and associations

A mnemonic is a memory trick that connects a new word to something you already know.

Because Korean words sound so different from English, making silly English associations is a great way to force the word into your memory quickly.

The weirder and funnier the image, the better your brain will remember it.

Here are a few simple examples:

• 바지 (ba-ji) means “pants”. Imagine you’re wearing really baggy pants.
• 거미 (geo-mi) means “spider”. Imagine a spider eating a gummy bear.
• 오리 (o-ri) means “duck”. Imagine a duck covered in Oreo cookie crumbs.

You can make these up yourself! Whatever pops into your head first is usually the strongest memory trigger.

Practice active output immediately

The final step to locking a word into your memory is to actually use it.

If you only read and listen (input), your brain treats the word as passive knowledge. You need to speak and write (output) to tell your brain, “Hey, this word’s important for my survival, keep it!”

Talk to yourself in your room. Write a quick journal entry. Text a Korean exchange partner.

This is also a great time to practice local vocabulary! If you have friends from different parts of Korea, using regional dialects (Satoori) will make your conversations much more memorable.

For example, if you want to say something’s “really” good, you’d use 진짜 (jin-jja) in standard Seoul Korean.

But if your friend’s from Busan (the Gyeongsang region), you could try using the local dialect word 억수로 (eok-su-ro) instead!

Seeing the surprised and happy reaction from your language partner when you use local words will create a strong emotional memory, ensuring you never forget the vocabulary.
