Language Disorder
Language disorder affects the acquisition and use of language. Difficulties may involve vocabulary, sentence structure and the ability to connect ideas in conversation, explanation or narrative.
Understanding and expression can differ
A child may speak often but struggle with complex instructions, time concepts or abstract language. Another may understand more than they can express. The pattern may affect spoken, written, signed or another form of language and can influence literacy, friendships, learning and the ability to ask for help.
Language disorder is different from a speech sound disorder, where the primary difficulty is producing sounds. Multilingualism does not cause it. Valid assessment examines every language the child uses and their genuine exposure, because normal second-language development should not be misclassified as disorder.
Assessment
- Persistent difficulties in understanding or producing language include reduced vocabulary, limited sentence structure and/or difficulty organising connected discourse.
- Skills are measurably below age expectations and restrict effective communication, participation, education or later employment.
- The pattern begins during early development and is assessed through history, observation, appropriate language measures and hearing evaluation.
- Hearing or sensory loss, motor difficulty, neurological conditions, intellectual development and broader developmental delay are considered without treating multilingual difference as impairment.
Communication support
Individual speech and language therapy may target vocabulary, grammar, comprehension, narrative and communication strategies. Caregivers can follow the child’s interests, expand what they say and allow response time without turning conversation into repeated testing.
School support includes short instructions in steps, visual information, checking understanding, pre-teaching vocabulary and extra processing time. The home language should be maintained. When speech alone does not meet communication needs, symbols or a communication device can provide immediate access and do not prevent speech development.
When to seek help
Seek assessment when a child consistently struggles to understand or express ideas compared with peers who have similar language exposure, or when frustration, play and learning are affected. Loss of previously acquired words or comprehension—especially sudden loss—requires medical and developmental assessment.
