Japanese verb conjugation is one of the most important parts of learning Japanese. Unlike English with its hundreds of irregular verbs, Japanese has only 2 irregular verbs. Once you learn the patterns, you can conjugate almost any verb correctly.

📚 The Three Verb Groups

Group 1: う-verbs

End in a う-column sound

  • 飲む (nomu) — drink
  • 書く (kaku) — write
  • 話す (hanasu) — speak
  • 待つ (matsu) — wait
  • 買う (kau) — buy

Group 2: る-verbs

End in -eru or -iru

  • 食べる (taberu) — eat
  • 見る (miru) — see
  • 起きる (okiru) — wake up
  • 教える (oshieru) — teach

Group 3: Irregular

Only two verbs!

  • する (suru) — do
  • 来る (kuru) — come

That's it. Japanese has only 2 irregular verbs. English has hundreds.

✨ Masu Form (Polite Present)

This is the form you'll use most in daily conversation. It's polite and safe in any situation.

Group 1Change last う-sound to い + ます → 飲む → 飲みます
Group 2Drop る + ます → 食べる → 食べます
Group 3Memorize → する → します、来る → きます

🔗 Te Form (て形)

The most versatile form. Used for requests (〜てください), progressive (〜ている), and connecting sentences.

む, ぶ, ぬ → んで → 飲む → 飲んで
く → いて → 書く → 書いて
ぐ → いで → 泳ぐ → 泳いで
す → して → 話す → 話して
つ, る, う → って → 待つ → 待って
Group 2 → て → 食べる → 食べて
Irregular → する → して、来る → きて

❌ Negative Form (ない形)

Group 1 — Change to あ + ない → 飲む → 飲まない
Group 2 — Drop る + ない → 食べる → 食べない
Group 3 — する → しない、来る → こない

⏪ Past Form = Te Form Pattern

The past form follows the exact same pattern as te-form — just replace て with た (and で with だ):

飲んで → 飲んだ | 書いて → 書いた | 食べて → 食べた

食べるnegative form食べない
話すpast form話した
するte-formして
来るnegative formこない

How to check yourself

  • Group 1 verbs change the final kana row before adding the ending.
  • Group 2 verbs usually drop る and attach the ending directly.
  • する and 来る must be memorized because they are irregular.
