What language-related condition involves an impaired ability to express oneself?

The condition characterized by an impaired ability to express oneself is known as expressive aphasia. This condition specifically affects a person's ability to produce language. Individuals with expressive aphasia may understand what others are saying and know what they want to say but struggle to form the words or sentences needed to effectively communicate their thoughts. This often results in speech that is laborious and may be limited to short phrases or even single words.

In contrast, receptive aphasia involves difficulty in understanding language, while global aphasia affects both expressive and receptive functions, leading to significant impairment in both speaking and comprehension. Conductive aphasia typically results in difficulty repeating phrases despite having the ability to understand and produce language appropriately in other contexts. Thus, expressive aphasia is distinctly focused on the challenges faced in language production, making it the correct choice for the condition described.
