Today we are going to learn expressions to say someone can do something.
1. [Person] wa [Action Noun] ga Dekimasu.
This sentence seems to be a Wa-ga construction. Although I wanted to use [Subject] for the part of [Person], but in the realm of Japanese teaching, wa-ga construction is thought to be understood by the following format;
2. [Topic] wa [Subject] ga [Stative Predicate].
I don’t think 2 is applicable to a sentence that describes “Someone can do something”. Let me say as follows; The subject of the sentence is [Person wa], and in order to identify what the person can do, particle “ga” is used just behind the action noun.
Examples of this construction are shown below;
3. Satou-san wa Eigo ga Dekimasu. (Sato-san can speak English.)
4. Suzuki-san wa Kuruma no Unten ga Dekimasu. (Suzuki-san can drive a car.)
“Eigo” in 3 may not be an action noun, but the word “Eigo” seems to have meanings of action like speaking English and listening to it. “Unten” in 4 apparently describes the action of driving, although it is a noun.
The construction 1 to say someone can do something uses an action noun. But, when it comes to an “action”, don’t you think it is better to use a verb? Yes, a verb can be used when saying someone can do something. In order to do this, you need to pay attention that Japanese is a language for which you have to distinguish nouns or verbs strictly. Therefore, the following is WRONG:
<WRONG> [Person] wa [Verb] ga Dekimasu.
The right expression should be as below, with a little simplification of 1;
1’. [Person] wa [Noun] ga Dekimasu.
In order to make “WRONG” right, you need to convert a verb to a noun. But how???
