1. The Heart of Every Japanese Verb: The Stem

Many beginners feel overwhelmed by the number of verb forms they encounter. However, every Japanese verb is built from two simple parts:

• The stem – the core meaning
• The ending – the part that changes

For example: たべる (taberu) – “to eat”
Stem: たべ (tabe)
Ending: る (ru)

Once you understand that endings create meanings, you no longer need to memorize long lists of separate verbs.

2. From “Taberu” to Many Forms: A Family Tree of Meanings

Here are some common forms that all come from the same stem:

• たべます – polite form (I eat)
• たべない – negative form (I don't eat)
• たべなかった – past negative
• たべたい – want to eat
• たべている – eating / regularly eat
• たべられる / たべれる – can eat (potential)
• たべさせる – to make/let someone eat (causative)
• たべられる – to be eaten (passive)

These are not separate vocabulary items—they are all children of the same parent verb. Once this idea clicks, Japanese verbs begin to feel much simpler.

3. What About “Iku”? Five-Step Verbs Follow the Same Logic

“Iku” (to go) seems irregular, but its pattern is also based on stem + ending.

• いかない – don't go
• いきたい – want to go
• いきます – polite
• いっている – going
• いった – went
• いかせる – to make/let go
• いける – can go

Even if the stem shifts, the underlying rule never changes.

4. “Miru” and “Neru”: Gentle, Easy One-Step Verbs

Two frequent verbs, みる (to see) and ねる (to sleep), change very cleanly.

Miru

• みます
• みない
• みたい
• みている
• みられる

Neru

• ねます
• ねない
• ねたい
• ねている

Their stability often helps learners feel more confident about verb endings.

5. Why Japanese Verb Forms Are Kinder Than English

In English the base word changes entirely: eat → ate → eaten → eating. Japanese keeps the meaning stable and simply modifies the ending. For many learners, this realization makes the language feel much more approachable.

6. Common Mistakes (And Why They Happen)

• ✕ たべたいます → You cannot attach tai and masu directly. Correct: たべたいです.
• ✕ いきたいます → Same rule. Correct: いきたいです.
• たべれる vs たべられる → Spoken vs textbook form. Both appear in real Japanese.

7. Everyday Conversation Examples

A few natural exchanges:

A: なにがたべたい？ (What do you want to eat?)
B: そばがたべたい。 (I want to eat soba.)

A: いついきたい？ (When do you want to go?)
B: あしたいきたいです。 (I want to go tomorrow.)

A: なにをみているの？ (What are you looking at?)
B: ともだちのしゃしんをみています。 (I'm looking at a friend’s photo.)

A: ぜんぶたべられる？ (Can you eat all of it?)
B: うーん…たべられないかも。 (Hmm… maybe I can't.)

9. Final Thoughts: Verbs Are Systems, Not Endless Lists

If you remember only one message from this article, let it be this:

Learn the base verb. Then let the endings do the rest.

Japanese verbs form a gentle, logical system once you understand the idea of the stem. Instead of memorizing hundreds of separate forms, you can build them naturally—just like a family growing from a single root.

I hope this guide helps Japanese feel clearer, kinder, and more enjoyable for you.
