Definition

Noun A type of aphasia, a language disorder, characterized by severely impaired ability to produce fluent speech or writing. Individuals with this condition typically understand language much better than they can express it. Their speech is often effortful, halting, and limited to short phrases, but the meaning is usually preserved.

Usage and Examples

This term is used in medical, neurological, and psychological contexts to diagnose and describe a specific language impairment.

• The stroke patient was diagnosed with Broca's aphasia, as he could only say single words like "yes" and "no" despite understanding questions.
• Her Broca's aphasia manifested as telegraphic speech, omitting small connecting words like "is" or "the."
• Research compares language recovery patterns in Broca's aphasia and Wernicke's aphasia.

Advanced Usage and Context

• Clinical Diagnosis: The term is used precisely to localize the likely brain area of damage (Broca's area in the frontal lobe) and to distinguish it from other aphasias, such as fluent (Wernicke's) aphasia or global aphasia.
• Synonyms in Context: It is often described as "non-fluent aphasia," "expressive aphasia," or "motor aphasia" to emphasize the characteristic difficulty in language production.

Variants and Related Words

• Aphasia: The general term for language disorder caused by brain damage.
• Broca's Area: The region in the brain's frontal lobe associated with speech production, damage to which typically causes Broca's aphasia.
• Telegraphic Speech: A common feature of Broca's aphasia where speech is reduced to essential content words, resembling a telegram.

Synonyms

• Expressive aphasia
• Non-fluent aphasia
• Motor aphasia

Related Phrases and Terms
