What does it means when a person doesn't speak English?

Answer 1

In most cases, it turns out that people who do not speak English do speak some other language, such as French, Spanish, Russian, Chinese, Portuguese, etc. There are also people below the age of two who have not yet learned to speak. When they do learn to speak, they may very well learn to speak English. If not, they will probably learn to speak some other language. There are also some people who never speak. Such people may be autistic, or may have some other mental or neurological problem. A stroke can damage the ability to speak.
