What is term for inability to speak?

The term for inability to speak is aphasia. Aphasia is a language disorder that affects a person's ability to understand or produce language. It can be caused by damage to the brain, such as from a stroke, head injury, or brain tumor. Aphasia can affect a person's ability to speak, understand speech, read, and write. There are several different types of aphasia, each with its own unique symptoms. The most common type of aphasia is Broca's aphasia, which affects a person's ability to produce speech. Wernicke's aphasia is another common type of aphasia, which affects a person's ability to understand speech. Aphasia can range in severity from mild to severe. Mild aphasia may only affect a person's ability to speak or understand certain words. Severe aphasia can make it impossible for a person to communicate at all. There is no cure for aphasia, but there are treatments that can help people with aphasia improve their communication skills. These treatments may include speech therapy, language therapy, and occupational therapy.
