Developmental language disorder in a multilingual childhood

A child may chat comfortably about a favourite game but struggle to explain an event, understand a long instruction or learn unfamiliar words. Adults can misread those differences as inattention or lack of effort. Language involves more than pronunciation: understanding and expressing vocabulary, sentences and connected ideas can affect participation. The useful question is not only 'Can the child talk?' but 'Can they use and understand language for the demands they face?'

Researcher Karla McGregor's clinical-focus article highlights how developmental language disorder can remain under-recognised and underserved. It draws on literature and bibliometric work, not a Hong Kong prevalence survey. Its message is still useful for families: a difficulty that is less visible can deserve substantial support. Strong interests, friendly conversation or good performance in another subject should not automatically close the discussion about a child's language needs.^[1][2]

The CATALISE consensus led by Dorothy Bishop and colleagues recommends language disorder terminology for difficulties with significant functional impact and a poor prognosis, with developmental language disorder used when there is no known differentiating biomedical condition. The terminology is intended to improve professional communication. It is not a checklist for families to apply independently, and it does not mean that a professional can predict a child's whole future from a brief encounter.

The panel also recognised that DLD can co-occur with other neurodevelopmental difficulties and does not require a large discrepancy between verbal and nonverbal abilities. This matters when a child has several overlapping needs. An explanation should make daily barriers clearer, not become a reason to debate whether a child is 'bright enough' to qualify for help. Ask the professional which term fits, why it is being used and what remains uncertain.^[2]

A Hong Kong child may hear Cantonese at home, encounter written Chinese and learn English at school, with different people using different languages. Knowledge and confidence can vary across those settings. A difficulty in the less familiar language cannot be interpreted as if exposure and teaching were identical. ASHA's multilingual guidance calls for culturally responsive assessment, an appropriate language history and language support such as a trained interpreter when required.

Do not interpret a language difference as a disorder, or dismiss a persistent difficulty simply because a child is multilingual. Share how communication works with familiar people in each language, including understanding as well as speech. ASHA also supports multilingualism rather than telling families to avoid languages. Keeping a home language can matter for relationships and identity; choosing assessment and support should not require parents to speak a language in which they cannot communicate comfortably.^[3]

Bring a few examples: instructions that were misunderstood, stories that were hard to explain, words that did not seem to stick, and occasions when communication went well. Ask which languages and abilities will be assessed, how the tools fit the child's experience and how school information will contribute. A translated test is not automatically equivalent to a test validated for that language and population. Request an explanation of what the results can and cannot show.

Also discuss listening, reading and classroom participation where relevant. Hulme and Snowling's review separates word decoding from reading comprehension, reminding us that recognising print is not the whole literacy task. A child who reads words accurately may still need help with the language of a passage. This connection supports broader questions, not a diagnosis of DLD from a reading score or an assumption that all literacy difficulties share one cause.^[3][4]

Work with the teacher and speech-language professional on a small, specific adjustment. Examples to discuss include explaining unfamiliar vocabulary before a lesson, presenting an instruction in shorter parts and asking the child to show what they understood. Simply asking 'Do you understand?' may not reveal the barrier. A visual example can be useful for some tasks, but it should clarify meaning rather than add another confusing stream of information.

These suggestions are not a complete intervention programme or a promise of benefit. Ask what skill is being taught, who will practise it with the child and how it will be used beyond a session. McGregor calls for clearer family communication and classroom collaboration; EDB's whole-school resources offer a local starting point for that discussion. Set a review date and include the child's account of whether participation has become easier.^[1][5]

At home, choose conversations and shared activities that allow the child time to respond. Let communication have a purpose beyond correction: making a choice, sharing a joke, asking for help or telling you something important. Ask the treating professional how any recommended practice can fit naturally into your household. A family should not have to turn every meal into a test or abandon enjoyable interaction in pursuit of a perfect sentence.

If a child continues to struggle, revisit the explanation and support rather than assuming they are not trying. DLD terminology can help adults coordinate, but the useful outcome is better access to learning and relationships. Respectful, language-sensitive support keeps both questions in view: what does this child need to learn, and what must the environment change so that they can already belong and take part?^[2][3][5]
