Summary

Teacher Lee Jung-woo introduces the first five of the eight parts of speech: nouns, pronouns, verbs, adjectives, and adverbs. He emphasizes that understanding both the concept and, especially, the role of each part of speech is foundational to English grammar. The remaining parts of speech—prepositions, conjunctions, and interjections—and sentence components are covered in later lessons.

Key Ideas About Parts of Speech

• The eight parts of speech are nouns, pronouns, verbs, adjectives, adverbs, prepositions, conjunctions, and interjections.
• These categories classify words by their common characteristics. Students do not need to memorize them in a particular order; they should focus on what each category means and does.
• A word may function as more than one part of speech and may have different meanings depending on its use. For example, book can be a noun or a verb, and light can be a noun, adjective, or verb.
• When learning vocabulary, students should memorize a word’s part of speech as well as its meaning. English does not always use words the same way Korean does; for example, an English adjective cannot simply be turned into a verb by changing its ending.

1. Nouns

• Concept: A noun names something, such as a person, object, animal, place, or idea. The thing named can be concrete or abstract.
• Roles in a sentence: Nouns can function as:
  • The subject
  • A complement
  • The object of a transitive verb
  • The object of a preposition

A noun’s role depends on where and how it is used. For example, History is the subject in “History is my favorite subject,” the complement in “My favorite subject is History,” and the object in “Tom likes History.”

2. Pronouns

• Concept: A pronoun replaces a noun, usually to avoid repeating a noun already mentioned. English tends to avoid unnecessary repetition.
• Roles: Because pronouns stand in for nouns, they can fill the same sentence roles: subject, complement, object of a transitive verb, or object of a preposition.
• Types introduced:
  • Personal pronouns, including first, second, and third person; they can refer to people and sometimes to animals or things.
  • Demonstrative pronouns, which point out or indicate something.
  • Indefinite pronouns, which refer to something not specifically determined.
  • Interrogative pronouns, used to form questions.
  • Relative pronouns, which the teacher says will be explained in detail later.

3. Verbs

• Concept: A verb expresses the subject’s action or state.
• The lesson distinguishes be verbs, ordinary verbs, and auxiliary verbs. Auxiliary verbs—such as can, may, will, should, and must—help other verbs grammatically and semantically.
• Verbs carry several kinds of grammatical information. The teacher highlights six areas to learn to recognize:
  • Subject–verb agreement: The verb form corresponds to whether the subject is singular or plural.
  • Tense: The verb indicates time.
  • Voice: The verb helps show whether the subject acts or is acted upon.
  • Auxiliary verbs: These contribute grammatical and semantic meaning.
  • Sentence pattern: The verb helps determine the sentence structure, including what can follow it.
  • Subjunctive mood: Verb forms help express situations contrary to fact or otherwise unreal.

The teacher encourages students to look beyond a verb’s basic meaning and learn to identify the information its form conveys. Labels such as transitive, intransitive, causative, and perception verbs describe groups or characteristics of verbs; the teacher says these terms will be clarified separately.

4. Adjectives

• Concept and role: Adjectives modify nouns and can also function as complements.
• A single-word adjective generally comes before the noun it modifies. An adjective phrase or other longer modifier may come after the noun.
• An adjective following a verb can describe the subject, functioning as a subject complement. In “The sky is beautiful,” beautiful describes the sky.

5. Adverbs

• Concept and role: Adverbs modify adjectives, other adverbs, verbs, or an entire sentence. They do not modify nouns.
• Do not identify an adverb by its spelling alone. Many adverbs end in -ly, but the suffix is not decisive: words such as friendly and lovely are adjectives.
• Determine whether a word is an adjective or adverb by asking what it modifies:
  • In “a very delicious cake,” very modifies the adjective delicious.
  • In “speak too slowly,” too modifies the adverb slowly, while slowly modifies the verb speak.
  • In “He runs fast,” fast modifies the verb and acts as an adverb; in “a fast horse,” it modifies the noun and acts as an adjective.
• An adverb at the beginning of a sentence may modify the whole sentence.

Overall Lesson

The teacher presents nouns, verbs, adjectives, and adverbs as the central parts of speech for understanding English sentence structure. Pronouns can be grouped with nouns because they take noun roles. Students should learn each word’s function in context—particularly what it modifies or what role it fills—rather than relying only on its meaning or form.
