What the analysis shows

  • Every part of the sentence

    Topic, subject, object, predicate, modifiers and adverbials, each named with its role in the sentence.

  • Particles and endings broken down

    See what 은/는, 이/가, 을/를 and endings such as -았-, -어요 and -(으)면 add to each word.

  • Long sentences split into clauses

    Clauses joined by endings like -아서, -지만 or -는 것 are separated and analyzed one at a time.

  • Explained in English

    Explanations are in English; the Korean stays exactly as you wrote it.

Example analysis

This is the kind of result you get. Each part of the sentence is named, then broken down into the word, its particle or ending, and what they do.

Input저는 어제 친구와 함께 영화를 봤어요.
Result

Structure: topic + time + adverbial (with whom) + object + predicate

  1. 저는: topic / subject
    • 저 (I, the humble form of 나) + 는 (topic particle; 은 after a final consonant)
  2. 어제: time adverb, "yesterday". It needs no particle.
  3. 친구와 함께: adverbial, who with
    • 친구 (friend) + 와 ("with"; 과 after a final consonant) + 함께 ("together")
  4. 영화를: object
    • 영화 (movie) + 를 (object particle; 을 after a final consonant)
  5. 봤어요: predicate
    • 보다 (to watch) → 보 + 았 (past tense), contracted to 봤 + 어요 (polite ending)

Meaning: "I watched a movie with my friend yesterday."

How it works

  1. Paste one Korean sentence (up to 600 characters) and press Analyze sentence.
  2. An AI model, given a fixed analysis format, splits the sentence into its parts and explains each particle and ending.
  3. The analysis appears as it is written. Copy it, or analyze the next sentence.

The analysis is AI-generated. It is reliable for standard written Korean, but can be wrong on slang, typos or unusual word order. Check anything important with a teacher or the Standard Korean Language Dictionary.
