Word-by-word breakdown

One lane per word — no nested boxes, just the gist.

단어(dan-eo, daneo)

The smallest independent unit of meaning in language

When to use

dictionary lookup, independent meaning, spacing unit

The nuance

단어 is a spacing unit that can stand alone with complete meaning or be found in a dictionary.

(gu)

A group of two or more words forming a meaningful unit but not a complete sentence

When to use

partial meaning unit, sentence part, incomplete subject-predicate

The nuance

A 구 consists of words performing a grammatical function but lacks a subject-predicate structure to be a full sentence.

문장(mun-jang, munjang)

A unit of speech with subject and predicate conveying a complete meaning

When to use

complete meaning, subject and predicate included, independent unit

The nuance

문장 includes subject and predicate and can independently convey complete meaning.

Real-world examples

  • 사과는 빨갛다.

    sa-gwa-neun ppal-gah-da., sa gwa neun ppal gah da.

    It is a complete sentence with subject (사과) and predicate (빨갛다).

  • 빨간 사과

    ppal-gan sa-gwa, ppal gan sa gwa

    A phrase formed by two words creating a meaningful unit, but not a full sentence.

  • 사과

    sa-gwa, sa gwa

    A single word with independent meaning, found in dictionaries.

  • 빨갛다 사과

    ppal-gah-da sa-gwa, ppal gah da sa gwa

    The word order is incorrect, so it is neither a natural phrase nor sentence.

  • 나는 학교에 간다.

    na-neun hak-gyo-e gan-da., na neun hak gyo e gan da.

    It has subject (나) and predicate (간다), making it a complete sentence.

  • 학교에 간다

    hak-gyo-e gan-da, hak gyo e gan da

    A sentence with omitted subject, still natural and complete.

  • 간다 학교에

    gan-da hak-gyo-e, gan da hak gyo e

    Word order is unnatural, so it is neither a natural sentence nor phrase.

  • 맛있는

    mas-iss-neun, mas iss neun

    A word functioning as an adjective with independent meaning.
