cannot/must not (social/moral)
Category: Expectation and Judgment
The grammar pattern "V(dictionary) / V(ない) + わけにはいかない" is used to express that one cannot do something or must do something due to social common sense, duty, or conscience. The dictionary form of the verb is used to convey the idea that something is not allowed or is a moral obligation, while the negative form of the verb is used to emphasize the necessity of doing something. This pattern is often used in situations where one feels a sense of responsibility or duty towards others, and is not suitable for expressing physical inability or general facts.
| Form | Pattern | Example |
|---|---|---|
| Dictionary form | V(dictionary) + わけにはいかない | 行くわけにはいかない (cannot go) |
| Negative form | V(ない) + わけにはいかない | 行くわけにはいかない (must go) |
| Adjective form | Adj + わけにはいかない | 大事なわけにはいかない (cannot be careless) |
