Can – Dekiru
An article on できる – can
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
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 が ga is used with dekiru.
(I) can’t do (it) (or できない。 dekinai)
sukai daibingu ga dekimasu ka?
Can (you) sky-dive?
|SIMPLE VERB + KOTO GA + DEKIMASU
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
natto o taberu koto ga dekimasen.
(I) can’t eat natto. (or できない。 dekinai)
toire ni iku koto ga dekimasu.
(I) can go to the bathroom.
And one that doesn’t use dekiru
|VERB + ~RARERU or ~ERU
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) 話せる hanaseru (can speak)
書く kaku (to write) 書ける kakeru (can write)
GROUP 2: add ~rareru ; Most verbs fall into this category
食べる taberu (to eat) 食べられる taberareru (can eat)
見る miru (to see) 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) 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)
pi-man o taberaremasu ka?
Can you eat green peppers? (It seems a lot of Japanese children hate green peppers)
pa-ti- ni koraremasu ka?
Can (you) come to the party?
