Fluent aphasia may involve which of the following language features?

Fluent aphasia is characterized by the production of fluent speech that is often grammatically correct but may lack meaningful content or exhibit nonsensical elements. One of the hallmark features of fluent aphasia is the substitution of words, where individuals may replace intended words with incorrect ones. This includes the use of neologisms, which are made-up words that the individual may believe have meaning or relevance. This can lead to speech that flows well in terms of rhythm and syntax but may not communicate clear or appropriate ideas, often making it difficult for listeners to understand the intended message. The presence of these word substitutions and neologisms is a key characteristic that distinguishes fluent aphasia from other types, thereby making this answer the most accurate.
