When making a passive sentence, the verb must be in the passive form. Please refer to yesterday’s post about how to conjugate a verb to its passive form.
Here is an active sentence;
1. Sensei wa Watashi o Home mashita. (The teacher praised me.)
It is the basic of Japanese that the particle “-o” indicates the object of a transitive verb. Actually, some intransitive verbs for movement also use “-o” for the places. But anyway, “Homeru/Homemasu” is a transitive verb. In this particular sentence 1, “Watashi” followed by the particle “-o” is the object of the action of praising. This sentence 1 is grammatically okay. But when a teacher praised you, probably you want to describe the occasion by making “Watashi” the subject of the sentence. This necessitates a passive sentence.
2. Watashi wa Sensei ni Homerare mashita. (I was praised by the teacher.)
The sentence 2 is a passive sentence. Let us examine how words are changed in the conversion from the active sentence 1 to the passive sentence2.
– “Watashi o” in the sentence 1 is the object of the action “praised”.
– “Watashi wa” in the sentence 2 is the subject of the action “was praised”.
– “Sensei wa” in the sentence 1 is the subject of the action “praised”.
– “Sensei ni” in the sentence 2 is the word that the passive action came from. The particle “-ni” has a function to indicate where (who) the action came from in the sentences of giving-receiving, passive and causative.
– “Home mashita” in the sentence 1 is the predicate verb in active voice.
– “Homerare mashita” in the sentence 2 is the predicate verb in passive voice. If you make Nai-form of “Homeru” in order to know which group the Homeru is, you will get “Hom<e>nai”. Then you can tell it is a Group2 verb. The passive form of Group2 verbs can be obtained with [Stem]+rareru/raremasu. Don’t omit “ra”, though youngsters often do.
So far for the sentences 1 and 2, we have been dealing with “Homeru/Homemasu (praise)” which is a transitive verb with the particle “-o”. But what will happen in the conversion from an active to a passive sentence which use a transitive verb with both the particles “-ni” and “-o”?
3. Haha wa Watashi ni Kaimono o Tanomi mashita. (My mother asked me to go shopping.)
This is an active sentence, and a transitive verb predicate sentence using not only “-o” but also “-ni”. In the conversion from the sentence 1 to 2, the object “Watashi o” in the 1 turned to be “Watashi wa” in the 2. But for this sentence3, can you make the word “Kaimono o(shopping)” the subject in a passive sentence? No.
– Kaimono wa Haha ga Watashi ni Tanomi mashita. (When it comes to shopping, my mom aeked me to do it.)
Uh, this is a wa-ga construction which I don’t like. Most importantly. this is not a passive sentence because the predicate verb “Tanomi mashita” is still in active voice. In order to make the sentence 3 a passive sentence, we turn the word with “-ni” to be the subject, that is, “Watashi ni” in the active sentence needs to the subject “Watashi wa” in the passive sentence.
4. Watashi wa Haha ni Kaimono o Tanomare mashita. (I was asked by my mother to go shopping.)
Please compare moves of the words and changes of the particles in the conversion from sentence 3 to 4. It is interesting that the particle “-ni” has different functions in the sentence 3 and 4. In the sentence3, “-ni” of “Watashi ni” is to indicate the destination that the action is heading towards (to whom to ask). On the other, “-ni” of “Haha ni” in the sentence4 is to indicate who (where) the action came from in a passive sentence as well as in the sentence2. The particle “-o” hasn’t changed in the conversion from the sentence 3 to 4. Although “-o” changed in the case of sentence 1 and 2, after all, we need to take note that the object and the particle “-o” is strongly tightened each other in the sentence which uses a transitive verb.
And “Tanomareru/Tanomaremasu” is the passive form of the “Tanomu/Tanomimasu”. Since the Nai-form of Tanomu is “Tanom<a>nai”, it is a Group1(-M) verb. The passive form of Group1 verbs can be obtained with [Stem]+areru/aremasu (Tanom+areru).
The verb used in the sentence 1 and 2 is “Homeru/Homemasu” which is a transitive verb with the particle “-o”. And the verb used in the sentence 3 and 4 is “Tanomu/Tanomimasu” which is a transitive verb with the particle “-ni” and “-o”. Thus, it makes sense to deal with transitive verbs when talking about passive sentence. However, there are some passive sentences using intransitive verbs in Japanese. Typical examples are as follows;
5. Watashi wa Densha no Naka de Kodomo ni Nakare mashita. (I have got a trouble because my kid was crying in a train.)
6. Ie ni Kaeru toki, Watashi wa Ame ni Furare mashita. (On the way home, I got a rainfall.)
“Nakare mashita” in the sentence 5 is the passive voice of the intransitive verb “Naku/Nakimasu”. And “Furare mashita” in the sentence 6 is the passive voice of the intransitive verb “Furu/Furimasu”. Some textbooks may introduce these passive sentences of intransitive verbs. But I think it is better to use transitive verbs only at the first stage of introduction of passive sentences. Teachers know many things. But teaching everything is not always good to help students learn the new items in the second language learning.
