expressive aphasia
Very LowTechnical/Clinical
Definition
Meaning
A language disorder caused by brain damage, where a person has difficulty producing speech and language despite largely preserved comprehension.
A type of aphasia, often resulting from a stroke or head injury affecting Broca's area in the frontal lobe of the brain. It is characterized by non-fluent, effortful, halting speech, with short phrases, omission of function words and grammatical morphemes (agrammatism), and often impaired writing, but with relatively intact understanding of spoken and written language.
Linguistics
Semantic Notes
The term is highly specialized to neurology, speech-language pathology, and cognitive neuroscience. It is not used in general conversation. 'Expressive aphasia' is often used interchangeably with 'Broca's aphasia', though some clinical distinctions can be made, with Broca's aphasia sometimes implying additional motor speech deficits (apraxia).

Usage
Context Usage
Business
Extremely unlikely to be used.
Academic
Primary context. Used in neuroscience, psychology, linguistics, and medical research papers and textbooks.
Everyday
Virtually never used. A layperson might say 'He had a stroke and can't speak properly'.
Technical
Core context. Used in clinical diagnosis, speech-language pathology reports, neurology consultations, and rehabilitation settings.
Examples
By Part of Speech
verb
British English
- The stroke caused him to aphasise expressively, leaving his speech halting and agrammatic.
- Clinicians assess how a patient aphasises to differentiate between fluent and non-fluent types.
American English
- The stroke caused him to become aphasic, with predominantly expressive symptoms.
- The neurologist noted the patient was aphasic, presenting with classic expressive deficits.
adverb
British English
- [No standard adverbial form. The concept would be phrased as 'with expressive aphasia'.]
American English
- [No standard adverbial form. The concept would be phrased as 'presenting expressively aphasic' in very technical jargon, but it's non-standard.]
adjective
British English
- His expressive-aphasic symptoms were most evident in his writing.
- The therapy focused on expressive-aphasic language production.
American English
- Her expressive aphasic speech was characterized by short, meaningful phrases.
- The study compared expressive-aphasic and receptive-aphasic patient groups.
Examples
By CEFR Level
- After his illness, he found it very hard to speak. The doctor called it aphasia.
- My grandfather had a stroke. He understands us but can only say a few words. This is called expressive aphasia.
Learning
Memory Aids
Mnemonic
Think EXPRESSive aphasia: trouble EXPRESSing yourself. The brain's 'express lane' for forming words is blocked.
Conceptual Metaphor
LANGUAGE PRODUCTION IS A MANUFACTURING LINE / LANGUAGE IS A TOOL: In expressive aphasia, the 'assembly line' for constructing sentences is damaged, while the 'warehouse' of word meanings (comprehension) remains intact.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque like '*экспрессивная афазия*'. The standard Russian equivalent is 'моторная афазия' (motor aphasia) or 'афазия Брока' (Broca's aphasia).
- Do not confuse with 'expressive' as in 'emotional' (эмоциональный). Here it refers specifically to language expression.
Common Mistakes
- Misspelling 'aphasia' as '*aphasia*' or '*aphazia*'.
- Confusing it with 'apraxia of speech', which is a motor planning disorder.
- Using it in non-medical contexts.
- Assuming it means the person cannot understand, which is the hallmark of *receptive* aphasia.

FAQ
Frequently Asked Questions
No. Mutism is an inability or refusal to speak. Individuals with expressive aphasia typically can produce some speech, but it is halting, effortful, and grammatically simplified. They are trying to communicate.
Yes, recovery is possible, especially with intensive speech and language therapy. The extent of recovery depends on factors like the size and location of the brain injury, the individual's age, and the timeliness of therapy.
Expressive aphasia is a language disorder affecting the formulation of words and sentences. Apraxia of speech is a motor disorder where the brain has difficulty planning the movements needed for speech. They can co-occur.
Absolutely not. Aphasia affects language processing, not intelligence. The person's thoughts, knowledge, and cognitive abilities outside of language are typically intact. They simply cannot find the words or grammar to express them easily.
