Here's why:
* "Deaf and mute" is the traditional term, but it's important to remember that "mute" can be considered outdated and potentially offensive.
* "Deaf and non-speaking" is a more contemporary and inclusive term that emphasizes the person's lack of verbal communication without using potentially insensitive language.
However, it's important to note that:
* Not all deaf people are non-speaking. Many deaf people communicate fluently using sign language.
* Not all non-speaking individuals are deaf. Some people may be non-speaking due to other conditions, such as cerebral palsy or autism.
Ultimately, it's best to avoid using generalizations and instead use language that respects the individual's specific circumstances and preferences.
