Transcortical sensory aphasia is characterized as a fluent aphasia. Fluency is determined by direct qualitative observation of the patient’s speech to determine the length of spoken phrases, and is usually characterized by a normal or rapid rate; normal phrase length, rhythm, melody, and articulatory agility; and normal or paragrammatic speech.

[3] [7] Expressive aphasia differs from dysarthria, which is typified by a patient's inability to properly move the muscles of the tongue and mouth to produce speech. Expressive aphasia also differs from apraxia of speech, which is a motor disorder characterized by an inability to create and sequence motor plans for conscious speech. [8]
William James was the first psychologist to describe the tip of the tongue phenomenon, although he did not label it as such. The term "tip of the tongue" is borrowed from colloquial usage, [2] and possibly a calque from the French phrase avoir le mot sur le bout de la langue ("having the word on the tip of the tongue").
Aphasia, also known as dysphasia, [a] is an impairment in a person’s ability to comprehend or formulate language because of damage to specific brain regions. [2] The major causes are stroke and head trauma; prevalence is hard to determine, but aphasia due to stroke is estimated to be 0.1–0.4% in developed countries. [3]

Aphasia does not affect a person's intellect or speech but Instead affects the formulation of language. [20] All areas of language are affected by aphasia including expressive and receptive language abilities. [20]
This is attributed to a reduced left hemisphere functional specialization for language. Taken from a measure of cerebral blood flow (SPECT) in phonemic discrimination tasks, children with mixed receptive-expressive language disorder do not exhibit the expected predominant left hemisphere activation.
