Japanese Verb Conjugation Lecture Notes

Introduction

  • Focus on Japanese verb conjugation.
  • Five vowels in Japanese: A, I, U, E, O.
  • All verbs end with U row kana.
  • Main purpose of conjugation: attach helper verbs/adjectives, unlike English which changes verb meaning.

Japanese Verb Conjugations

Basic Concept

  • Shifting the U to different rows alters conjugation.
  • Examples: 飲む becomes 飲み, 飲ませる, etc.

Types of Verbs

  • 五段 (Godan) Verbs: Regular pattern, e.g., 飲む (to drink), 使う (to use), 話す (to speak).
  • 一段 (Ichidan) Verbs: Simpler changes, e.g., 食べる (to eat).

Verb Stems and Their Uses

E-Stem (電用形 - Connective Form)

  • Most versatile; attaches to many words.
  • Used for helper adjectives/verbs like たい.
  • Examples: 飲みたい (want to drink), 話し合う (discuss).
  • Can nominalize a verb: 休む (rest) to 休み (a rest), 夏休み (summer vacation).

A-Stem

  • Simple, mainly for negative forms.
  • Negative helper verbs/adjectives: ない, ず, ぬ.
  • Example: 知る (to know) becomes 知らない (do not know).
  • Exception: Verbs ending in う change to は.
  • Receptive verbs: れる/られる (receiving action).

O-Stem

  • Takes helper verb う to form volitional "let's".
  • Examples: 飲もう (let's drink), 使おう (let's use).

Imperative and Hypothetical Forms

  • Imperative: Commanding form, e.g., 飲め (drink!), 死ね (die!).
  • Hypothetical: Uses particle ば or helper verb る to indicate condition or potential.
  • Examples: 飲めば (if drink), 行ける (can go).

Advanced Concepts

Combination of Forms

  • Complex sentences by combining different forms: causative, receptive, negative, past.
  • Example: 飲ませられなかった (was not made to drink).

Sentence Structure

  • A does B: Verb-ending sentence structure.
  • A is B: Adjective-ending sentence structure using helper adjectives like たい.

Common Misconceptions

  • Traditional charts sometimes combine O-Stem and A-Stem as 未然形.
  • Understanding the separation of conjugations and helper verbs avoids errors.
