Overview of Japanese Verb Types

Japanese verbs are categorized mainly into three groups based on their conjugation patterns: Group 1 (Godan verbs), Group 2 (Ichidan verbs), and irregular verbs. Understanding these categories is essential for mastering all Japanese verb conjugation.

• Group 1 (Godan verbs): These are the most common verbs, characterized by their stem ending changes depending on the conjugation form. They typically end with -u sounds like -ku, -su, -tsu, -nu, -bu, -mu, and -ru.
• Group 2 (Ichidan verbs): Also called ru-verbs, these verbs end in -iru or -eru and have a simpler conjugation pattern where the -ru ending is dropped before adding conjugation endings.
• Irregular verbs: These include verbs like する (to do) and くる (to come), which have unique conjugation patterns that must be memorized separately.

The Basics of All Japanese Verb Conjugation

Conjugation in Japanese modifies verbs to express tense, mood, voice, politeness, and other grammatical nuances. The main conjugation forms every learner should master include:

• Plain form (Dictionary form): The base form of the verb used in casual speech and dictionary entries.
• Polite form (ます form): Used in formal contexts, created by attaching ます to the verb stem.
• Negative form: Expresses negation, commonly formed with ない in plain speech and ません in polite speech.
• Past tense: Indicates completed actions, formed by changing the verb ending accordingly.
• Te-form (て form): Used for connecting clauses, making requests, and forming continuous tenses.
• Potential form: Expresses ability or possibility.
• Volitional form: Used to express intention or suggestion.

Mastering these forms allows learners to build sentences accurately and communicate effectively in Japanese.

Detailed Guide to Group 1 Verb Conjugation

Group 1 verbs, or Godan verbs, conjugate by changing the final syllable of the verb stem. Here are the essential conjugation patterns for all Japanese verb conjugation in this group:

Plain and Polite Forms

• Dictionary form: e.g., 書く (kaku) – to write
• Polite form: Replace the final -u with -i and add ます → 書きます (kakimasu)

Negative Form

• Plain negative: Replace final -u with -a and add ない → 書かない (kakanai)
• Polite negative: Replace final -u with -i and add ません → 書きません (kakimasen)

Past Tense

The past tense in Godan verbs involves replacing the final syllable with its corresponding past form:

• For verbs ending in -ku: 書く → 書いた (kaita)
• For -su: 話す → 話した (hanashita)
• For -tsu: 待つ → 待った (matta)
• For -nu: 死ぬ → 死んだ (shinda)
• For -bu: 遊ぶ → 遊んだ (asonda)
• For -mu: 飲む → 飲んだ (nonda)
• For -ru: 取る → 取った (totta)

Te-Form

The te-form is similar to the past tense endings but ends with て or で:

• -ku → -いて (書く → 書いて)
• -gu → -いで (泳ぐ → 泳いで)
• -su → -して (話す → 話して)
• -tsu, -ru, -u → -って (待つ → 待って)
• -mu, -nu, -bu → -んで (飲む → 飲んで)

Potential Form

For Godan verbs, change the final -u to -e and add る:

• 書く → 書ける (can write)
• 話す → 話せる (can speak)

Volitional Form

Change the final -u to -ō (using the long vowel sound):

• 書く → 書こう (let’s write)
• 飲む → 飲もう (let’s drink)

Detailed Guide to Group 2 Verb Conjugation

Group 2 verbs, also known as Ichidan or ru-verbs, have a simpler conjugation pattern. These verbs end with -iru or -eru.

Plain and Polite Forms

• Dictionary form: 食べる (taberu) – to eat
• Polite form: Drop -る and add ます → 食べます (tabemasu)

Negative Form

• Plain negative: Drop -る and add ない → 食べない (tabenai)
