Expressive language disorder is a communication disorder in which a child has ongoing trouble putting thoughts into words and sentences. The child may have a small vocabulary, use short or incomplete sentences, make grammar errors, or struggle to tell a story in order, even though they often understand much of what others say. Expressive language disorder (sometimes shortened to ELD) is not about how clearly a child pronounces sounds. It is about finding the right words and combining them to share thoughts and feelings. Today, specialists usually diagnose it as a language disorder or developmental language disorder (DLD).
What is expressive language?
Expressive language is the way we use words, sentences, gestures, and writing to share information, ideas, needs, and feelings. It includes vocabulary (knowing and finding the right words), grammar and sentence structure, and discourse, which means organizing language into longer explanations or stories. Receptive language is the other side: understanding what others say or write.
Most children develop both skills without special teaching. A child with an expressive language disorder develops expressive language more slowly or differently than expected for their age, and the difficulty does not simply go away with time.
Receptive vs. expressive language disorder
Parents often search for the difference between receptive vs expressive language disorder. The key difference is direction:
- Expressive language disorder: trouble using language to express ideas. The child may know what they want to say but cannot put it into words easily.
- Receptive language disorder: trouble understanding language, such as following directions, answering questions, or understanding stories.
- Mixed receptive-expressive language disorder: difficulties with both understanding and using language.
In practice, many children have some difficulty in both areas, even if one is more obvious. The current diagnostic manual used by clinicians, the DSM-5, combines these older categories into one diagnosis called language disorder, with a description of which areas are affected.
Developmental language disorder (DLD)
Developmental language disorder is the term many researchers and speech-language pathologists now use for a language disorder that is not explained by another condition, such as hearing loss, autism, intellectual disability, or a brain injury. It was agreed on by an international panel of experts to replace older, inconsistent labels such as specific language impairment (SLI), language delay, and expressive language disorder.
DLD is common. It is one of the most frequent developmental conditions in young children, yet it is often missed because the child may seem quiet, shy, or inattentive rather than obviously struggling. When a language disorder happens alongside another condition, such as autism, it is usually described as a language disorder associated with that condition.
Signs of expressive language disorder by age
Children's language development follows different paths, and a toddler with a language delay may still catch up. No single sign means a child has a disorder. The following are common signs that may be worth discussing with a pediatrician or speech-language pathologist.
Toddlers (about 18 months to 3 years)
- Says few words for their age, or learns new words slowly
- Is not combining words into short phrases by around age 2
- Relies mainly on pointing, gestures, or leading adults by the hand
Preschool (about 3 to 5 years)
- Uses shorter, simpler sentences than peers
- Leaves out small words and word endings ("He go park," "two cat")
- Has trouble asking and answering questions
- Uses general words like "thing" or "stuff" instead of specific names
School age
- Struggles to retell a story or explain events in order
- Has word-finding problems, pauses often, or talks around a word
- Makes grammar errors that peers no longer make
- Finds written expression hard, including organizing ideas for essays
- Has trouble joining conversations, which can affect social communication and friendships
Language problems can also affect reading. Many children with DLD have trouble with reading comprehension, and some also have difficulty with decoding or dyslexia. Frustration with communication can also show up as behavior problems.
Causes and risk factors
In most cases, there is no single known cause. Research suggests genetics play a role, because language disorders often run in families. Other factors linked to a higher risk include a family history of language or reading difficulties, being born prematurely, and being male, though any child can have a language disorder. Language disorders are not caused by parenting style or by children learning more than one language. Bilingual children with a language disorder show the difficulty in all of their languages, not only in English.
A language disorder can also occur with other conditions, including hearing loss, autism, ADHD, intellectual disability, and traumatic brain injury.
How expressive language disorder is diagnosed
A speech-language pathologist (SLP) diagnoses language disorders. An evaluation usually includes:
- A parent interview about development, health, and family history
- Standardized tests of expressive and receptive language
- A language sample, such as having the child tell a story or talk about a picture
- Observation of how the child communicates at home or school
- A hearing screening or referral for a full hearing test, to rule out hearing loss
For children under 3, families can ask for a free evaluation through their state's early intervention program under IDEA Part C. For bilingual children, the SLP should look at both languages. In schools, a speech-language evaluation can be part of a full special education evaluation, and parents can request one in writing. Schools also have a duty under Child Find to identify children who may need services.
Expressive language disorder treatment and classroom support
Speech therapy with a speech-language pathologist is the main expressive language disorder treatment. The SLP sets goals based on the child's needs, such as building vocabulary, using complete sentences, using correct grammar, or telling stories with a clear beginning, middle, and end. Therapy is often play-based for young children and linked to classroom work for older students. Progress takes time, and many children continue to need some support as language demands grow in later grades.
Teachers and parents can help in everyday settings:
- Give extra wait time before expecting an answer.
- Model correct language by repeating the child's idea in a complete sentence ("Yes, the dog is running fast").
- Teach new vocabulary directly, with pictures and repeated practice.
- Use visual supports, sentence starters, and graphic organizers for writing.
- Allow other ways to show knowledge, such as drawing, choosing answers, or using assistive technology.
IDEA category: speech or language impairment
Under the IDEA, one of the 13 disability categories is "speech or language impairment." The federal definition describes it as a communication disorder, such as stuttering, impaired articulation, a language impairment, or a voice impairment, that adversely affects a child's educational performance. A child with an expressive language disorder may qualify for an IEP under this category if the disorder affects their learning and the child needs special education.
Speech-language services can be the child's main special education service or a related service alongside other support. Some children with language disorders qualify under a different category, such as specific learning disability when written language is a main concern. Children who do not need special education may still receive accommodations through a Section 504 plan.
This article gives general information only. If you are worried about your child's speech or language development, talk with your child's doctor or a licensed speech-language pathologist.
Frequently asked questions about expressive language disorder
What is an example of expressive language disorder?
A 6-year-old who understands stories well but says, "Me want go outside. Him took my thing," and cannot explain what happened on the playground in order, may have an expressive language disorder. Only a speech-language pathologist can make that determination.
Is expressive language disorder a form of autism?
No. A language disorder can happen in autistic children, but many children with language disorders are not autistic. Autism involves differences in social communication and restricted or repetitive behaviors, while a language disorder is about learning and using language itself.
Can expressive language disorder be cured?
Some late-talking toddlers catch up on their own, but a true language disorder usually continues in some form into the school years and beyond. There is no quick cure, but with speech therapy and support many children make strong progress and learn to communicate effectively.
Is expressive language disorder a disability?
It can be. Under IDEA, a language disorder that adversely affects a child's educational performance and creates a need for special education can qualify as a speech or language impairment. Eligibility is decided by the school team after an evaluation.
What is the difference between a speech disorder and a language disorder?
A speech disorder affects how sounds are made, such as articulation, fluency (stuttering), or voice. A language disorder affects understanding or using words and sentences. IDEA groups both under "speech or language impairment."
