Why frequency order beats a random word list
In any language a small set of words does most of the work, and Korean is no exception: a few hundred high-frequency items carry a large share of everyday conversation. Learning theme-by-theme from a textbook inverts this. You memorize fruit names before you can say "I think so".
The second principle: learn words inside short sentences rather than as isolated entries. Memorizing 물 (water) alone leaves you stuck at the moment of speaking; memorizing 물 주세요 ("water, please") gives you something usable immediately. Read the tables below aloud in phrases and they will last far longer.

25 core verbs and adjectives
Korean verbs and adjectives all end in -다 in dictionary form, but conversation uses the polite -아요/어요 form, so the table lists both. Adjectives behave like verbs in Korean. 좋다 conjugates the same way 가다 does, which is one less rule to learn.

| 하다 (hada) | 해요 (haeyo) | to do |
| 가다 (gada) | 가요 (gayo) | to go |
| 오다 (oda) | 와요 (wayo) | to come |

Korean numbers: two systems, learned side by side
Korean has two number systems. The Sino-Korean set (일, 이, 삼) is used for dates, money, phone numbers, and minutes; the native Korean set (하나, 둘, 셋) is used for ages, counting objects, and the hour. They routinely appear in the same sentence. 3:30 is 세 시 삼십 분, native for the hour and Sino for the minutes.
| Number | Sino-Korean (dates, money, minutes) | Native Korean (age, counting, hours) |
|---|---|---|
| 1 | 일 (il) | 하나 (hana) |
| 2 | 이 (i) | 둘 (dul) |
| 3 | 삼 (sam) | 셋 (set) |
| 4 | 사 (sa) | 넷 (net) |
| 5 | 오 (o) | 다섯 (daseot) |
| 6 | 육 (yuk) | 여섯 (yeoseot) |
| 7 | 칠 (chil) | 일곱 (ilgop) |
| 8 | 팔 (pal) | 여덟 (yeodeol) |
| 9 | 구 (gu) | 아홉 (ahop) |
| 10 | 십 (sip) | 열 (yeol) |
Two practical notes: the native system only goes up to 99, after which Sino-Korean takes over; and 하나·둘·셋·넷 shorten to 한·두·세·네 before a counter word: 한 개 (one item), 두 시 (two o'clock), 세 명 (three people). Learning that shift early removes most number stumbles.
The small words that hold sentences together
Nouns and verbs alone produce choppy speech. The words below carry little meaning on their own but connect clauses and add nuance. They make a beginner sound more fluent than their vocabulary size suggests.
| KoreanRomanization | Meaning |
|---|---|
| 그리고geurigo | and (between sentences) |
| 그런데geureonde | but, by the way |
| 그래서geuraeseo | so, therefore |
| 정말jeongmal | really, truly |
| 조금jogeum | a little |
| 많이mani | a lot |
| 빨리ppalli | quickly |
| 천천히cheoncheonhi | slowly |
| 같이gachi | together |
| 다시dasi | again |

How to make the words stick
- Ten words a day, each inside a short sentence, so 물 주세요 rather than 물 alone.
- Use spaced repetition: review after 1, 3, 7, and 14 days, right as the word starts to fade.
- Say them out loud. Words you have only seen do not surface when you need to speak.
- Use the day's words in a real conversation once. Retrieval under pressure moves them into long-term memory.
The most common slip after memorizing words is dropping the particles that turn them into a sentence. Pairing this list with 은/는, 이/가, and 을/를 makes vocabulary start behaving like speech.
Frequently asked questions
How many Korean words do I need to hold a conversation?
Roughly 500 to 1,000 high-frequency words carry most everyday conversation. The 100 here are the starting core, with nouns, verbs, adjectives, numbers, and connectors in balance, which is enough to build your first real sentences.
Why does Korean have two sets of numbers?
One set came from Chinese (일, 이, 삼) and one is native Korean (하나, 둘, 셋), and each kept different jobs. Dates, money, and minutes use the Sino set; ages, counting, and the hour use the native set, so telling the time requires both.
Can I learn Korean words in romanization?
It helps for the first few days, but leaning on it locks in wrong pronunciation. Hangul takes only days to learn, so reading the alphabet first and then memorizing words in Hangul is faster overall.
