禁止形

「禁止形」 is a verb form used to give commands, instructing others not to perform a certain action. This form carries a strong tone of imposition or threat, so its usage is quite limited. Here are some contexts where the prohibitive form can be used:
- Everyday conversations: In most cases, this form is used by men. Men in a higher position or older age may use it when speaking to those beneath them, such as a father to a child, a superior to a subordinate, etc. When men speak to each other, the softening particle よ is sometimes added at the end of the sentence to make it gentler.
- When there is little concern for the feelings of the person being communicated to. For example, when giving instructions in a workshop, in emergency situations like fires, earthquakes, etc. Even in these cases, the users are typically men in higher positions.
- When shouting slogans or cheering during rehearsals, school sports activities, club activities, etc. In these cases, the users are often women.
- When emphasizing simplicity for effective communication, such as in traffic signs.
