Summary

The lecture reviews the nine parts of speech in Korean, first grouping them by whether their forms change, then explaining their roles and main subtypes.

1. Inflected and uninflected words

• Inflected words change form as endings are attached. The main examples are verbs and adjectives. The particle 이다 (“to be”) is also exceptional in that it changes form.
• Uninflected words generally keep the same form. These include nouns, pronouns, numerals, determiners, adverbs, particles, and interjections.
• Parts of speech can also be grouped by their sentence roles: substantives, modifiers, relational words, independent words, and predicates.

2. Substantives: nouns, pronouns, and numerals

Substantives can serve as major sentence components, such as subjects or objects.

• Nouns

  • Independent nouns can stand on their own; dependent nouns need a preceding modifier. The lecture uses 것 (“thing”) as an example of a dependent noun.
  • Proper nouns identify a particular person, place, brand, or other individual item. Common nouns name a general class or group.
  • Nouns can also be classified as animate (people and animals) or inanimate (such as plants and water).

• Pronouns

  • Personal pronouns include first-, second-, and third-person forms. The lecture also mentions unknown, indefinite, and reflexive pronouns.
  • Demonstrative pronouns point out people, things, places, or concepts.

• Numerals

  • Numerals express quantity or order, such as “one, two, three” and “first, second, third.”

3. Modifiers: determiners and adverbs

Modifiers describe or qualify other words.

• Determiners modify substantives. The lecture identifies three broad types:

  • Qualitative or state determiners, which describe a quality or condition.
  • Demonstrative determiners, which point out a person or thing.
  • Numeral determiners, which indicate number or amount.

• Adverbs chiefly modify verbs, but may also modify other adverbs or an entire sentence.

  • A constituent adverb modifies one part of a sentence.
  • A sentence adverb expresses the speaker’s attitude toward the sentence as a whole.
  • Conjunctive adverbs, such as words meaning “however” or “but,” clarify the relationship between sentences.

The instructor notes that distinguishing similar categories, such as demonstrative pronouns and demonstrative determiners, is a common test issue.

4. Particles

Particles attach to other words and help show grammatical relationships or add nuance.

• Case particles mark a word’s role in the sentence.
• Conjunctive particles connect words or phrases.
• Auxiliary particles add emphasis or other shades of meaning rather than simply marking grammatical roles.
• Most particles do not inflect. 이다, the predicative particle, is an exception and takes changing forms, as in 학생이다 (“is a student”) and 학생인 (“who is a student”).

5. Interjections

Interjections can stand independently and express emotion, a response, or the speaker’s intention—for example, expressions like “Ah” or “Yes.”

6. Predicates: verbs and adjectives

Predicates inflect and form the core of what is stated about the subject.

• Verbs express actions or processes; adjectives express qualities or states.
• Transitive verbs require an object, while intransitive verbs do not.
• Both verbs and adjectives can be main or auxiliary predicates. Auxiliary predicates add meanings such as continuation, completion, or other nuances to the main predicate. The lecture recommends studying their subtypes in more depth later.
• Adjectives include words describing qualities or states, as well as demonstrative adjectives meaning roughly “like this,” “like that,” or “in that way.”

7. Study advice

The instructor advises students seeking exam information to ask a trustworthy subject instructor rather than relying only on exchanges among students in online communities.
