Self Introduction
Introduce your name, nationality, and role using polite speech.
Self-introduction in Korean follows a predictable structure: name, nationality, occupation, and optionally a closing phrase. The full pattern is 안녕하세요. 저는 [name]이에요/예요. [nationality] 사람이에요. [job]이에요. 잘 부탁드립니다. The choice of 이에요 vs 예요 depends on whether the preceding word ends in a consonant or vowel — 이에요 after consonants (학생이에요), 예요 after vowels (의사예요).
잘 부탁드립니다 is a closing phrase with no clean English equivalent. Literally 'please take care of me', it functions in Japanese-influenced Korean business culture similar to よろしくお願いします. It is appropriate in any first-meeting context — at work, in a class, when meeting your partner's family. For English speakers it can feel oddly humble, but it is the expected formal closing for Korean self-introductions, and skipping it can come across as abrupt.
은/는 (Topic Marker)
Use 은/는 after a noun to mark the topic. Use 은 after a consonant, 는 after a vowel.
이/가 (Subject Marker)
Use 이/가 to mark the subject. 이 follows consonants, 가 follows vowels.
How It Works
은/는 and 이/가 are the pair that causes more confusion than anything else in beginner Korean, and the reason is that English marks neither of them. Both attach to nouns, both can appear where English would use a subject, and dictionaries translate both as nothing at all.
The mechanical part is easy. 은 and 이 follow consonants; 는 and 가 follow vowels. 이름은, 학생은 versus 저는, 누구는. This is the same euphonic alternation you have seen throughout Korean.
The functional difference is what takes time. 은/는 marks the topic — it announces what the sentence is about, often with a sense of 'as for X'. 이/가 marks the grammatical subject and tends to introduce new or specifically identified information. 저는 학생입니다 sets you up as the topic and then describes you: 'as for me, student'. 이름이 지수예요 identifies which thing has the property: 'the name is Jisu'.
A useful early heuristic: use 은/는 when you are establishing what you are talking about, especially for yourself at the start of a conversation, and use 이/가 when answering 'which one' or introducing something for the first time. This will not cover every case — the full distinction takes months — but it is accurate enough to carry you through self-introductions without sounding wrong.
Where You'll Hear It
Self-introduction is where you will produce these particles first, and the pattern is highly formulaic. 저는 이름이 [name]이에요 or more simply 저는 [name]이에요. In a classroom or a first day at work you will hear a series of people running the same template, which makes it excellent listening practice.
Nationality and occupation follow immediately. 저는 일본 사람이에요 and 저는 회사원이에요 are sentences you will say many times, and 한국 사람 / 일본 사람 is the standard construction — Korean builds nationality as 'country + person' rather than with a dedicated adjective.
The particles matter beyond introductions, though. Korean drops pronouns constantly, so the particle is often the only marker of who is doing what. 저는 is frequently the one word that tells a listener you are talking about yourself rather than continuing about someone else. Learners who omit particles to save effort end up with sentences that are grammatically ambiguous in exactly the way Korean speakers rely on them not to be — and in casual speech, where particles genuinely do get dropped, the omission follows rules of its own rather than being free.
Cultural & Language Note
The 은/는 versus 이/가 distinction maps almost perfectly onto Japanese は versus が, which is an enormous advantage. 저는 학생이에요 and 私は学生です carry the same topic-marking nuance, and the contrastive reading of 은/는 works the same way too. English speakers have to learn this distinction from scratch; Japanese speakers largely already have the instinct and mainly need to attach it to new forms.
Common Mistakes to Avoid
The particle choice is not the hard part for Japanese speakers — the form is. 은 and 이 attach after a consonant, 는 and 가 after a vowel. 저는 (vowel) but 선생님은 (consonant). Learners also over-use 저 in casual settings; 저 is the humble 'I' and pairs with polite speech, while 나 is the plain form used with friends.
How to Practice This Lesson
Do not try to master 은/는 versus 이/가 now. It is a multi-year distinction and attempting to nail it at this stage produces paralysis. Instead, memorise three complete sentences and use them as templates: 저는 [name]이에요, 저는 [nationality] 사람이에요, 저는 [job]이에요.
Get the phonetic rule fully automatic, because that part you genuinely can finish today. Write ten nouns, half ending in vowels and half in consonants, and attach the correct particle to each. Check, then do it again until you stop pausing.
Japanese speakers should lean on the は/が intuition — it transfers well and will be right most of the time — but should make a note each time they meet a sentence where Korean and Japanese diverge. Keeping a short list of those mismatches is far more useful than reading another explanation of the distinction.
