Understanding Japanese Conjugation: The Foundation of Japanese Grammar

Japanese conjugation differs significantly from English and many other languages, as it involves changing the endings of verbs and adjectives rather than using auxiliary verbs. These changes indicate tense, mood, voice, and politeness level, which are crucial for accurate and culturally appropriate communication.

Types of Verbs in Japanese

Before diving into conjugation patterns, it’s important to understand the classification of Japanese verbs, as each type follows different conjugation rules:

• Godan Verbs (五段動詞): Also known as consonant-stem verbs, these verbs conjugate by changing the final consonant of the stem.
• Ichidan Verbs (一段動詞): Also called vowel-stem verbs, these verbs conjugate by dropping the final -ru and adding endings.
• Irregular Verbs: A small set of verbs (e.g., する “to do”, 来る “to come”) that conjugate uniquely.

Understanding these categories is the first step to mastering Japanese conjugation.

Essential Japanese Verb Conjugations

Japanese verbs conjugate to express various grammatical functions. Below are the most important conjugations every learner should master:

1. The Plain (Dictionary) Form

The base form of a verb, used in casual speech, dictionary entries, and when forming other conjugations.

2. The Polite Form

Used in formal or respectful contexts, this form typically ends with -ます (masu). For example:

• 食べる (taberu) → 食べます (tabemasu) — to eat
• 行く (iku) → 行きます (ikimasu) — to go

3. The Negative Form

Used to indicate negation, this form differs depending on verb type:

• Godan verbs: Replace the final -u sound with the corresponding -a sound + ない (nai), e.g., 書く (kaku) → 書かない (kakanai)
• Ichidan verbs: Drop -る and add ない, e.g., 食べる (taberu) → 食べない (tabenai)

4. The Past Form

Indicates actions completed in the past. The endings vary by verb class:

• Godan verbs: Change the final -u to the corresponding -ta or -だ form, e.g., 話す (hanasu) → 話した (hanashita)
• Ichidan verbs: Drop -る and add た, e.g., 食べる (taberu) → 食べた (tabeta)

5. The Te-Form

The te-form is crucial for connecting clauses, making requests, and forming continuous or progressive tenses. Examples include:

• 書く (kaku) → 書いて (kaite)
• 食べる (taberu) → 食べて (tabete)

Advanced Japanese Conjugation Forms

Once comfortable with the basics, learners should explore more complex conjugations to express nuances in meaning and politeness.

1. Potential Form

This form expresses the ability or possibility of doing something.

• Godan verbs: Change the final -u to the corresponding -e sound + る, e.g., 書く (kaku) → 書ける (kakeru)
• Ichidan verbs: Replace -る with -られる, e.g., 食べる (taberu) → 食べられる (taberareru)

2. Passive Form

Used to indicate that the subject is acted upon.

• Godan verbs: Change the final -u to the -a sound + れる, e.g., 書く → 書かれる
• Ichidan verbs: Replace -る with -られる, e.g., 食べる → 食べられる

3. Causative Form

Expresses making or letting someone do something.

• Godan verbs: Change the final -u to the -a sound + せる, e.g., 書く → 書かせる
• Ichidan verbs: Replace -る with -させる, e.g., 食べる → 食べさせる

4. Conditional Form

Used to express “if” statements.

• ば-form: Add ば to the verb stem (e.g., 食べれば – if eat)
• と-form: Use と for natural consequences (e.g., 行くと – if/when go)

Japanese Adjective Conjugation

In addition to verbs, Japanese adjectives also conjugate to show tense and politeness, which is vital for descriptive expressions.

1. i-Adjectives

• Present positive: おいしい (oishii) — delicious
• Past positive: おいしかった (oishikatta)
• Present negative: おいしくない (oishikunai)
• Past negative: おいしくなかった (oishikunakatta)

2. na-Adjectives

• Present positive: 静か (shizuka) — quiet
• Past positive: 静かだった (shizukadatta)
• Present negative: 静かじゃない (shizuka janai)
• Past negative: 静かじゃなかった (shizuka janakatta)
