JAPANESE SUBJECT PARTICLE が
Welcome to another particle lesson! This time, we will focus on how to use が, the Japanese subject particle.
The Japanese language, like the Korean language, uses several particles to mark a noun, verb, adjective, or sentence.
BASIC STRUCTURE OF SUBJECT PARTICLE が
The subject of a sentence is what “does” the verb, or “is” the adjective or noun.
PATTERN
Subject + が
| japanese | ROMAJI | ENGLISH |
|---|---|---|
| 車がほしい | kuruma ga hoshii | I want a car |
| 彼が読む | kare ga yomu | He reads |
But what about topic particle marker は? Like in this sentence:
| 私はジョンです | watashi wa jon desu | I am John |
There is no subject marked with が in this sentence.
But what is a sentence without a subject?
Many times in the Japanese language, information can be easily inferred through context.
Even though the subject is not stated in the sentence, it is implied that the subject and the topic are the same.
DIFFERENCES BETWEEN は AND が
Differences between は and が can be tricky, as we can also say:
| 私がジョンです | watashi ga jon desu | I am John |
instead of:
| 私はジョンです | watashi wa jon desu | I am John |
The difference between these two sentences, and understanding how to use the subject particle が, comes down to understanding the difference between は and が.
In the sentence 私がジョンです, there is a nuance that speaker is emphasizing the word 私 (I), as in, “I am John (someone else is not John)”. This could be in response to the question, “who is John?”, or, “is he John?”
- In this way, the subject particle が can emphasize the thing that comes before it.
- は, on the other hand, can give more emphasis on what comes after it.
We can only use が when the subject is something uncertain, like なにか (nanika, something), or だ れか (dareka, someone).
USING が WITH CLAUSES
We also need to pay attention to the use of particle が in clauses. It can indicate the subject of a particular clause, but not the subject of the sentence as a whole.
| 私は家が揺れるのを感じた | watashi wa ie ga yureru no wo kanjita | I felt the house shake |
If we break the sentence down into its parts, it is easier to see what the subject, object, and verb of the sentence are.
| 私は | 家が揺れるのを | 感じた |
| I (topic) | the house shake (object) | felt (verb) |
Even though particle ga is after 家 (ie, house), the subject of the sentence is not the house.
It is the subject of the clause. The house is not the thing that “did the verb” of the sentence, which is “felt”. It was “I” who did the feeling. So, “I” is actually the subject of the sentence.
So in the previous example, the topic and the subject were the same.
OMITTING THE SUBJECT
Sometimes, the subject of the sentence is omitted entirely because it can be inferred from the context.
If you just felt the house shake from an earth quake, you could turn to your friend and say:
家が揺れるのを感じた without starting with 私は , and it would be obvious from context you were talking about yourself.
In this next example, the subject has been omitted as well.
| 今日はスーパーに行きます | kyou wa suupaa ni ikimasu | Today I will go to the supermarket |
In this sentence, there is nothing marked with が, and there is something marked with は. But the topic of the sentence is not the subject of the sentence.
Today is not what is going to the supermarket. In this case, it is likely again to be “I”, and there isn’t much need to specify that directly.
If one did choose to say, 今日は私がスーパーに行きます it would probably be to emphasize the fact that today, the speaker is the one going to the supermarket.
It is like saying, “On another day, someone else might be going to the supermarket. But, as for today, I am going to the supermarket.”
EXCEPTIONS
There are times when the difference between using は and が is only a matter of nuance. But there are also times when only one or the other is used.
We can only use が when the subject is something uncertain, like なにか (nanika, something), or だ れか(dareka, someone).
Something that is unknown cannot be the topic of a sentence:
| だれかがきています | dareka ga kiteimasu | Someone is coming. |
We can only use は when the sentence is something ending in a negatively conjugated verb.
| コーヒーは飲みません | kōhī wa nomimasen | I don’t drink coffee. |
Japanese learners will spend a lot of time trying to understand the differences between は and が and how to use the subject particle properly.
The best ways to do this are:
- 1) By trial and error, and being corrected by native speakers
- 2) By listening and reading to native speech and text, and paying attention to the ways they use these particles.
