Use てほしい to tell someone directly or indirectly that you want them to do something. It's common in everyday conversation when making requests or expressing wishes about another person's actions. The subject of the desire (the person who wants) is usually 'I' (watashi), but it can be shown with は or が. The person you want to act is marked with に.

This pattern is softer than a direct command like ～てください, but it still expresses a clear wish. You can use it when asking a friend to help, telling a family member to do something, or even complaining about someone's behavior. Unlike ～てください, which is a direct request, てほしい often implies 'I wish you would...' and can sound a bit demanding if used with people you're not close to, so it's best with friends or people you know well.

For negative, use ～ないでほしい to say you don't want someone to do something. For example, '来ないでほしい' means 'I don't want you to come.'
