Korean is a fascinating language spoken by over 75 million people worldwide. Understanding Korean grammar is essential for fluency, and the good news is that Korean follows highly consistent patterns once you learn the fundamentals.
What Makes Korean Grammar Unique?
Subject-Object-Verb (SOV) Word Order
Korean places the verb at the end of sentences, unlike English's Subject-Verb-Object order.
- English: I eat rice (Subject-Verb-Object)
- Korean: 저는 밥을 먹어요 (I rice eat - Subject-Object-Verb)
You must wait until the end of a sentence to know what action is being performed.
Particles System (조사)
Korean uses particles—small words attached to nouns—to indicate grammatical relationships. These show whether a word is the subject, object, location, or serves another function.
Key particles:
- 이/가 (i/ga) - subject marker
- 을/를 (eul/reul) - object marker
- 에 (e) - location or time
- 은/는 (eun/neun) - topic marker
Politeness Levels (존댓말/반말)
Korean has a sophisticated politeness system built into the grammar. Verb conjugations change based on your relationship with the listener, their age, social status, and formality of the situation.
Three main levels:
- Formal polite (합니다체): Formal situations, presentations, news
- Informal polite (해요체): Everyday polite conversation
- Casual (반말): Close friends, family, younger people
Honorifics System (높임말)
Beyond politeness levels, Korean has honorifics that show respect to the person you're talking about. Special verb forms, vocabulary, and particles are used when discussing someone of higher status or elders.
Agglutinative Nature
Korean adds suffixes to words to express grammatical relationships. A single verb can have multiple endings attached:
- 먹다 (meokda) = to eat
- 먹었어요 (meogeosseoyo) = ate (polite, past)
- 먹고 싶어요 (meokgo sipeoyo) = want to eat (polite)
- 먹을 수 있어요 (meogeul su isseoyo) = can eat (polite)
Korean Grammar Core Components
1. Verb Stems and Endings
Every verb has a stem (core meaning) and endings that indicate tense, politeness, and mood.
2. Particles
Attach to nouns to show their grammatical function in the sentence.
3. Conjugation Patterns
Regular rules for changing verb and adjective forms across tenses and politeness levels.
4. Sentence Connectors
Ways to link clauses and create complex sentences (-고, -지만, -아서/어서, etc.).
5. Modifiers
How to describe nouns and create relative clauses using verb/adjective endings.
Verbs and Adjectives
In Korean, adjectives function like verbs—they conjugate for tense and politeness. This differs from English where adjectives are static.
- 크다 (keuda) = to be big
- 커요 (keoyo) = is big (present, polite)
- 컸어요 (keosseoyo) = was big (past, polite)
Key Features That Simplify Korean
No Articles
Korean doesn't use articles like "a," "an," or "the."
Optional Plural Markers
Plural forms are often optional when context makes the number clear.
No Grammatical Gender
Unlike Spanish, French, or German, Korean has no grammatical gender for nouns.
Phonetic Writing System
Hangul is completely phonetic—what you see is what you say (mostly).
Consistent Rules
Korean has far fewer irregular verbs compared to English or French.
No Tones
Unlike Chinese or Thai, Korean doesn't use tones to distinguish meaning.
