A quarter of young people have been verbally bullied (called names) in the past year, a survey has found out.
The charity Anti-Bullying Alliance spoke to nearly 1,000 11- to 16-year-olds about how bullying affects them.
This week is Anti-Bullying Week.
Events are taking place around the UK to try to highlight the problem of bullying using words and calling names.
The theme for the week is "Stop and think - words can hurt".
People are worried that bullying with words might be seen as less serious as other kinds, like when bullies hit you.
Campaigners say that bullying with words can be just as hurtful - because of how it makes you feel.
