Can - Dekiru

Untitled Document

A YOUNG CLAY: "Teacher, Can I use the bathroom?"
TEACHER:
"I don't know, Can you?"

This page is dedicated to the teacher who taught me the difference between "can" and "may"


Let's look at how to say "can" in Japanese:

First the 2 ways that use できる dekiru or the -masu form できます dekimasu (they both mean "can do", "able to do")

NOUN + GA + DEKIMASU

日本語ができる。
nihongo ga dekiru.
[lit. Japanese can do.]
(I) can speak Japanese.

This just says, "Japanese can", but of course what is meant is (I) can speak (or write) Japanese. Usually pronouns are left out when the context is clear. For more on pronoun usage, click here.

Notice ga is used with dekiru.

EXAMPLES:

できません。
dekimasen.

(I) can't do (it) (or
できない。 dekinai)

スカイダイビングができますか?
sukai daibingu ga dekimasu ka?

Can (you) sky-dive?

 

SIMPLE VERB + KOTO GA + DEKIMASU

日本語を話すことができる。
nihongo o hanasu koto ga dekiru.
[Japanese speaking-thing can do]
I can speak Japanese.

To add a verb, you must stick koto ga dekiru to the simple verb. A simple verb usually ends with a 'ru' or a 'su,' and is the shortest form of the verb.

X tabemasu (masu form of 'to eat')
O taberu (simple form) + koto ga dekiru

X hanashimasu (masu form)
O hanasu (simple form) + koto ga dekiru

EXAMPLES:

納豆を食べることができません。
natto o taberu koto ga dekimasen.

(I) can't eat natto. (or
できない。 dekinai)

トイレに行くことができます。
toire ni iku koto ga dekimasu.

(I) can go to the bathroom.

And one that doesn't use dekiru

VERB + ~RARERU or ~ERU

日本語が話せる。
nihongo ga hanaseru.
[Japanese can speak]
I can speak Japanese

This basically means the same thing, but uses a different way. I won't say much on this now, as I want to concentrate on dekiru. But "can" can be acheived by changing the verb's ending. To learn about verb groupings click here

GROUP 1: ADD ~eru
話す hanasu (to speak) Arrow Image 話せる hanaseru (can speak)
書く kaku (to write) Arrow Image 書ける kakeru (can write)

GROUP 2: add ~rareru ; Most verbs fall into this category
食べる taberu (to eat) Arrow Image 食べられる taberareru (can eat)
見る miru (to see) Arrow Image 見える mieru

GROUP 3: These are the irregular verbs. These 2 are all you have to worry about
来る kuru (to come) Arrow Image 来られる korareru (can come) [A shorter version 来れる koreru is also in use - Maybe recent Japanese has been working to shorten these long tongue twisters.]
* する suru (to do) becomes できる dekiru (as discussed above)

EXAMPLES:

ピーマンを食べられますか?
pi-man o taberaremasu ka?
Can you eat green peppers? (It seems a lot of Japanese children hate green peppers)

パーティーに来られますか?
pa-ti- ni koraremasu ka?
Can (you) come to the party?

ima ne watashi wa setsumei

ima ne watashi wa setsumei wo shite iku
(I'm gonna explain this)
~(verb)koto ga arimasu= have done something
you cannot use KANOU DOUSHI可能 動詞 え団 (verbs in potencial plain) in this conjugation, you just have to put the verb plain
ex: tabemasu (masu-kei)
taberu (jisho kei)(dictionary form)
I can eat a cake:ke-ki wo taberu koto ga dekimasu
ke-ki wo taberareru (可能 kanou)
ke-ki wo taberaremasu
taberu : 2nd Group
I baked a cake: ke-ki ga dekimashita
ke-ki ga dekita
die (shinu)
you can die: anata wa shinde mo ii desu
anata wa shinemasu

P.D:do not get confused among KANOU AND UKEMI are diferent
KANOU is potencial and UKEMI is passive voice

来られるは受身形で

来られるは受身形です
来れるは可能形です
可能形と受身形は違います

so how do you say 'may i

so how do you say 'may i (eat this)?'

(^.^)Y !!!!

Hi, "Koto ga dekimasu" or "dekiru" is the same, you can use any... And, if the verb is closely associated w/ its direct object, you can attach either Koto ga dekiru or dekiru to it.
Hope this helps. Bye-bye!!!!(^0^)

What about the verb, ”die”

How would I use that?

Shinu

しぬ・死ぬ

まったん's picture

死ねる

あなたが死ぬ事ができる。

あなたが死ねる。

Both say "You can die."

This is so confusing...

but it's really helpful. I'm going to have to go over it a few times to get it completely.

Nevermind!!!

I have come to the realization!!!

XD

I ended up answering my own question!!!

I thought Hanaseru looked familiar.

I remember Hanasemasu.. being used somewhere.

Therefor it should be Hanasemasen for the negative?

Oni's picture

Yup

Yuppers.
話せません is negative (polite)
話せない is also negative (plain)

Negative eru

How would I put eru in the negative?

Would I simply add nai?

As in..

Chugokugo ga hanaseru nai.

中国語が話せるない。

?

Would this be: I can't speak Chinese.

Or, for the negative.. Am I better off using Dekinai and Dekimasen?

Oni's picture

~える is like any other

~える is like any other ~る verb. Just drop the る then add ない・ません.

話す→話せる→話せない (can't speak)
