Overview

The potential form is used to say that someone can or is able to do something. It is one of the most useful verb forms for talking about your abilities and skills.

Forming the potential

The potential form changes depending on the verb group.

ru-verbs: drop る and add られる

see → can see

u-verbs: change the final vowel from the u-row to the e-row, then add る

write → can write
read → can read
speak → can speak
drink → can drink

Irregular verbs:

きごう→
do → can do
きごう→
come → can come

できる — the most important potential verb

For する-compound verbs (勉強する, 運動する, etc.), the potential is できる. It is also used on its own to express general ability.

Can you speak Japanese?

が or を

With potential verbs, the object can be marked with が or を. が is very natural and common, especially in spoken Japanese.

Saying "I can't do X"

Use the negative form: ~られない (ru-verbs) or the e-row + ない (u-verbs).

Saying "I could do X" (past)

Conjugate the potential verb in the past tense.

Yesterday
I was finally able to cook by myself.

Note: potential and passive look the same for ru-verbs

For ru-verbs, the potential and passive forms are identical.

can eat (potential) OR is eaten (passive)
Context and particles clarify the meaning.

Dialogue

It's already been six months since I started studying Japanese. At first, I couldn't even read hiragana, but now I can read it fluently. I've also become able to read katakana a little.

Last week, I was able to speak a little with a Japanese friend. I was nervous, but I can say simple greetings. I can say "arigatou" and "douzo" with confidence.

But I still can't write kanji very well. I also can't read difficult texts all the way through yet. With listening, I can't understand unless the other person speaks slowly.

Even so, today in class I was able to catch a little of what the teacher said, and I was very happy. My goal is to become able to write emails in Japanese. I think if I practice a little every day, I will surely become able to do it.
