In short. You learn that 3 is 삼, then hear someone count people with 세 instead. Dotori Learn Korean Numbers helps beginners work out which reading fits the situation. Choose a number and a counter, compare the readings and open the explanation. You can start with the expression you need, then practise its rule in a short lesson or quiz.
Dotori Learn Korean NumbersLearn Korean numbers through meaning, counters and short practice.
The same written counter can have different meanings
Three minutes is 삼 분, or sam bun. Three people, when counted politely with 분, is 세 분, or se bun. The written number and counter look the same. The meaning tells you which number system to use. The app places these two expressions side by side. Each has a button that explains the reading.
| Situation | Expression | Reading |
|---|---|---|
| Minutes of waiting | 3분 | 삼 분 — sam bun |
| People, counted politely | 3분 | 세 분 — se bun |
| The hour on a clock | 3시 | 세 시 — se si |
| Counting animals | 3마리 | 세 마리 — se mari |
This is why learning two lists of numbers is only the beginning. A counter is the word used with a number to count something. Learn the number together with that word and its meaning to get an expression you can use. The comparison screen also covers other easily confused meanings. For example, 번 appears in both numbered items and repetitions.
Clock time brings both systems into one expression
Three oh three is 세 시 삼 분. The hour uses a native Korean number. The minutes use a Sino-Korean number. Open the clock view and change the hours and minutes to see the whole expression. It is a useful example when you know both number lists but hesitate when they appear together.
Native numbers also change before counters. 셋 becomes 세 in 세 마리, for example. See the result, then check its explanation to connect the form with its rule. Selected examples include dictionary-style pronunciation, IPA and romanization as reading aids.
Go from a comparison to lessons and review
Seven lessons cover both number systems, ten-thousand grouping and native numbers. They also cover forms before counters, everyday counters, meaning differences, time and age. They are all open from the start. Look up an expression first and return to its lesson when you want to understand the pattern.
