Last updated on 10 June 2026

Sign language is not just for deaf people. It goes without saying, but it goes even better by saying it. Parents, educators, teachers, teachers, students, many people are in contact with deaf people.
Sign language is a language in its own right. It's even pretty trendy right now. So much better. For example, it is used in a simplified version to communicate with a baby or a very small child.
