Could you give you some emotions?
Yes, of course you can give yourself good emotions and bad emotions.
How would you choose to express your strongest emotions if you did not have or could not use language?
If a person's language could not communicate emotions, the person would use their physical bodies through gestures, pointing, hitting, kicking, etc. If a person could not use language or their bodies to express emotions, they could still use facial expressions. If a person could not use language, their bodies, or facial expressions to express emotions, they would need to use assistive devices.
