Let’s dive in!
1. What Are Ru-Verbs?
Japanese verbs are divided into 3 groups:
- Ru-verbs (る-verbs) ← today’s focus
- U-verbs (う-verbs)
- Irregular verbs
Ru-verbs are verbs that usually end in -eru or -iru, such as:
- 食べる（たべる / taberu）– to eat
- 見る（みる / miru）– to watch
- 寝る（ねる / neru）– to sleep
- 起きる（おきる / okiru）– to get up
Be careful: some verbs that end in -iru or -eru are not ru-verbs (you’ll learn more in future lessons!).

5. FAQ – Frequently Asked Questions
- QHow do I know if a verb is a ru-verb?
- A
Ru-verbs usually end in -eru or -iru, and the syllable before る has an i or e vowel sound. But be careful — there are exceptions! For example:
かえる (kaeru – to return) is a u-verb, not a ru-verb.
- QCan I use “ます / ません” with all verbs?
- A
Yes, but the way you add ます or ません depends on the verb group. Ru-verbs are the most regular, so they’re a great starting point.
- QWhat does “dictionary form” mean?
- A
It’s the plain, base form of a verb – the one you’ll find in dictionaries.
Example: たべる, みる, ねる, etc.
- QWhat’s the difference between ru-verbs and u-verbs?
- A
U-verbs have different conjugation rules. For example, のむ (to drink) becomes のみます, not のます. You’ll learn more about u-verbs in the next unit!
