| Form | Hangul | Romanization | When to Use |
|---|---|---|---|
| Standard | 이 | i | Most everyday situations |

Number Basics and Pronunciation
Reading and Writing 이 in Hangul
The core word for "2" is 이 (i), written with two strokes in Hangul as ㅇ + ㅣ. It appears in many compound numbers like twenty 둘스물 (dulmeot) and twenty-two 스물이 (seumul-i).
Formal vs Casual Contexts
In everyday settings, 이 is neutral and widely used. Honorific contexts may still use 이 but with polite verb endings, while native Korean du (두) suits informal counting of items or people among peers.
Essential Vocabulary and Examples
Numbers Built on 이
Combine 이 with other elements to form common numbers. Twenty is 스물 (seumul), thirty is 서른 (seoreun), and twelve is 열두 (yeoldu), illustrating how the base adapts in different positions.
Phone Numbers and Addresses
For phone numbers and addresses, speakers typically use the Sino-Korean style, so 2 becomes 이 (i) and appears as part of sequences such as 이일이이삼 (2123) or street numbers like 2가 (2-ga).
Grammar and Usage Details
Counters and Measure Words
When counting with native Korean numerals, pair du (두) with appropriate counters like 개 (gae) for general objects. With Sino-Korean 이, general counters are less common in everyday enumeration beyond fixed phrases.
Position in Compound Numbers
In numbers above twenty, 이 shifts to the ones place and often appears with euphonic changes, such as 스물이 (seumul-i) in speech, where sound linking improves natural flow.
Practical Tips and Everyday Practice
- Practice saying pairs of common numbers, such as twelve (열두) and twenty-two (스물둘), to internalize how 이 connects in different positions.
- Use flashcards that pair Hangul, Romanization, and audio to reinforce accurate pronunciation of 이 in isolation and within compounds.
- Integrate the number into daily routines by stating prices, floor numbers, or time expressions aloud during commutes or at home.
- Observe how native speakers combine 이 with counters and time expressions in dramas or vlogs to notice natural linking and stress patterns.
FAQ
Reader questions
How do I pronounce 이 correctly in Korean?
The pronunciation is a crisp "ee" similar to the "ee" in "see," produced with the tongue high and front in the mouth, avoiding any diphthong ending.
Should I use du or i when telling age?
Use du (두) in casual speech for ages, while choose i (이) or the full Sino-Korean form for more structured or semi-formal settings, especially around adults outside your peer group.
What does 이 appear in dates and years?
In dates and years, 이 is part of the Sino-Korean system, so February is 이월 (iwol), the 2nd day is 이일 (il), and 2024 is 이천이십사 (icheonsipsa).
Are there exceptions or special readings for this number?
Yes, when 2 appears as a prefix in month names, it becomes 이월 instead of a du-based form, and historical or formal readings may favor Sino-Korean patterns over native alternatives.
