In this lesson, I am going to introduce another function of Japanese particle de (で).
You know that most Japanese particles have multiple functions. Depending on situations, the same particle can represent different meanings in a sentence.
Japanese particle de (で) sometimes indicates a cause or a reason. But there's a regulation that you need to take note of.
Let's see what's the sentence pattern like...
The "Noun" that is often used with this particle de (で) as a cause is a noun which indicates a particular kind of event, such as 事故 (jiko - accident), 火事 (kaji - fire), 大雨 (ooame - heavy rain), 大雪 (ooyuki - heavy snow), 地震 (jishin - earthquake), 津波 (tsunami - tidal wave), 病気 (byouki - sickness), 仕事 (shigoto - work), etc.
As you can see, these events are mostly natural phenomena, disasters, happenings, events, etc.
Let's use some examples to show how to use this function of Japanese particle de (で)...
事故 で 電車が止まりました。
jiko de densha ga tomarimashita
Meaning: The train was stopped due to accident.
台風 で 家が壊れました。
taifuu de ie ga kowaremashita
Meaning: The house was destroyed due to typhoon.
大雨 で 木が倒れました。
ooame de ki ga taoremashita
Meaning: The tree fell down due to heavy rain.
地震 で 屋根が崩れました。
jishin de yane ga kuzuremashita
Meaning: The roof of the house collapsed due to earthquake.
火事 で 怪我をしました。
kaji de kega wo shimashita
Meaning: I got injured due to fire.
病気 で 会社へ行けませんでした。
byouki de kaisha e ikemasendeshita
Meaning: I couldn't go to the office due to illness.
You cannot have expression containing speaker's volitional action in the Result sentence. Therefore this particle is used in the following way:
-> Due to a cause/reason, an uncontrollable event happened.
Let's use some examples to show what it means in the regulation...
病気 で 学校を休むつもりです。 X
byouki de gakkou wo yasumu tsumori desu X
病気 で 学校を休みたいです。 X
byouki de gakkou wo yasumitai desu X
病気 で 学校を休みました。 O
byouki de gakkou wo yasumimashita O
Based on the regulation, only example 3 is correct because the other two examples show the speaker's volitional actions in the Result sentences.
In example 1, you are thinking of being absent from school. You have a choice of going or not going to school. But you are thinking of not going to school because of your illness. This is a volitional action and thus failed to meet the regulation.
In example 2, you want to be absent from school. It's your desire since たい-form is being used. As this's also a volitional action, it failed to meet the regulation.
For example 3, the Result sentence 学校を休みました (gakkou wo yasumimashita) can be a volitional action by itself. However, because it's used together with the particle de (で) in the sentence, it's no more a volitional action. You couldn't go to school due to your illness and you have no choice but to stay at home.
For example 2 and 3, you have to use から (kara) or ので (node) to make the sentences correct.
病気だ から 学校を休むつもりです。 O
byouki da kara gakkou wo yasumu tsumori desu O
Meaning: I am sick, therefore I am thinking of not going to school.
病気な ので 学校を休みたいです。 O
byouki na node gakkou wo yasumitai desu O
Meaning: I am sick, therefore I want to be absent from school.
Therefore, for Noun で Result, the Result has to be:
Let's do some practice to check if you understand when to use Japanese particle de (で) as a cause/reason correctly. Connect the two sentences in the following examples. The first sentence is the reason and the second sentence is the result. Use the particle de (で) if you think it can be used. Use から (kara) if you think otherwise.
raishuu wa natsu yasumi desu. nihon e asobi ni ikimasu
taifuu desu. soto e deraremasen
byouki desu. gakkou wo yasumou to omoimasu
byouki desu. byouin e ikimashita
ii tenki desu. sanpo wo shimasu
ii tenki da kara, sanpo wo shimasu
Meaning: The weather is good, therefore I am going for a walk.
You can decide to go for a walk or do other things that you like. So it's a controllable event. Therefore you have to use から (kara) here.
How well have you done? Have you got all your answers right?
