Developmental Language Disorder
What is Developmental Language Disorder?
Developmental Language Disorder (DLD), ICD-11 6A01.2, is a persistent difficulty in understanding and using spoken language that is not explained by hearing loss, intellectual disability, autism or a neurological condition. Early features include late words, short or jumbled sentences, trouble following instructions and word-finding difficulty. Hearing is always checked first, and diagnosis follows a clinician-led assessment.
Your child understands the world and wants to connect — words are simply taking longer to arrive, and that difference has a name.
In short
Developmental Language Disorder (DLD) is a persistent difficulty in learning, understanding and using spoken language that is not explained by hearing loss, intellectual disability, autism or a known neurological condition. In ICD-11 it maps to developmental language disorder (6A01.2) under neurodevelopmental disorders. A child with DLD has the desire and the intelligence to communicate, but the language system itself develops differently — affecting how they grasp words, build sentences or follow conversation.What it can look like
In early childhood, DLD may show as a late first word or slow vocabulary growth, short or jumbled sentences, difficulty following longer instructions, trouble finding the right word, or struggling to tell a simple story in order. Some children mainly have difficulty expressing themselves (expressive), some mainly with understanding (receptive), and many have both. Importantly, these differences persist beyond the typical range of late talking and are not because the child cannot hear, cannot think clearly or does not wish to engage — which is exactly why DLD is recognised as its own profile rather than a passing delay.When to seek a check
A single late milestone is rarely cause for alarm, but it is worth a developmental review if language seems markedly behind peers by around age 2–3, if your child is hard to understand by age 3, if they struggle to follow simple two-step instructions, or if early words appeared and then stalled. Earlier support builds language during the brain's most responsive years — and a check first rules out hearing difficulties, which are always assessed before any language conclusion.The Pinnacle way
This is general information, not a diagnosis — a clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care, never from an app or checklist. Our pathway begins with hearing clearance, then individualises speech therapy to each child's developmental language disorder profile — drawing on 25 million+ therapy sessions of experience across 70+ centres.Trusted sources

What to watch
Late first words or slow vocabulary growth, short or jumbled sentences, difficulty following two-step instructions, trouble finding the right word, and struggling to tell a simple story in order — persisting beyond typical late talking.
Try this at home
Slow your own speech, gain eye contact before speaking, and expand on what your child says — if they say 'car', you reply 'yes, a big red car' — modelling the next step without correcting or pressuring.

Frequently asked
Is Developmental Language Disorder the same as a speech delay?
Not quite. A delay often means language is following the usual path but later than peers and may catch up. DLD is a persistent difference in how language is learned and used that continues beyond the typical late-talking window. A clinician-led review tells the two apart.
Does DLD mean my child has low intelligence?
No. DLD is recognised precisely because language difficulty occurs despite the child having the cognitive ability to communicate. It is not explained by intellectual disability, hearing loss or autism.
At what age can DLD be identified?
Concerns are often raised around age 2–3 when language lags markedly behind peers. Hearing is always checked first, and a clinician forms any conclusion through a structured assessment as language and attention mature.
Can children with DLD improve with support?
Yes. Individualised speech and language therapy during the early, responsive years builds understanding and expression. Many children make meaningful gains with consistent, tailored support.
