Defining and Constructing the Causative-passive Form

In Japanese grammar, the causative-passive form denotes that someone or something caused an action to occur and emphasizes the subject that experienced or endured that action. This form combines two important grammatical functions: causation and passivity.

To create the causative-passive form, follow these simple steps:

1. Begin with the causative form of the verb.
2. Transform the verb into its passive counterpart.

Let us consider the verb “to read” – 読む (よむ, yomu).

1. First, change it into the causative form: 読ませる (よませる, yomaseru).
2. Next, convert it to the passive form: 読ませられる (よませられる, yomasareru).

Now, we have the causative-passive form: 読ませられる (よませられる, yomasareru).

Rules for Conjugating Verbs in the Causative-passive Form

The conjugation rules for verbs in the causative-passive form depend on the verb type: ru-verbs (group 1), u-verbs (group 2), or irregular verbs (group 3).

Group 1: Ru-verbs

1. Drop the る (ru) ending of the verb.
2. Add させられる (saserareru) to the remaining stem.

Example: 食べる (たべる, taberu) → 食べさせられる (たべさせられる, tabesaserareru)

Group 2: U-verbs

1. Change the final う (u) sound of the verb to an あ (a) sound.
2. Add せられる (serareru) to the remaining stem.

Example: 書く (かく, kaku) → 書かせられる (かかせられる, kakaserareru)

Group 3: Irregular verbs

1. Memorize the specific conjugation rules for the two irregular verbs, する (suru) and 来る (くる, kuru).

Example: する (suru) → させられる (saserareru) and 来る (くる, kuru) → 来させられる (こさせられる, kosaserareru)

Using the Causative-passive Form in Sentences

The basic structure of a causative-passive sentence is as follows:

[Experiencer/Subject] は/が [Causer] に [Verb in Causative-passive form] ます。

For example: 私は先生に宿題を出させられました。 (わたしはせんせいにしゅくだいをださせられました。- Watashi wa sensei ni shukudai o dasaseraremashita.)
Translation: I was made to submit my homework by the teacher.

Note that the particle に (ni) indicates the actor that caused the action.

Practical Tips for Mastering the Causative-passive Form
