Final answer:
Aphasia is the condition that Katy is experiencing after her car accident, which has limited her ability to speak to only one word.
Step-by-step explanation:
This scenario is an example of aphasia. Aphasia refers to a language disorder that can occur after a brain injury, such as a stroke or traumatic brain injury. It often affects a person's ability to speak or understand language.
In Katy's case, sustaining serious brain damage from the car accident has led to her being able to speak only one word. This condition is known as expressive aphasia, which is characterized by difficulty producing or forming words.
It is important for Katy to work with healthcare professionals, such as speech therapists, who specialize in treating aphasia to help her regain her language abilities.
