You moved abroad for a better life. But somewhere between the school runs, the Zoom calls, and the packed weekends, you noticed something: your child has stopped replying in your language. They understand everything. They just will not speak it. And that gap between what they know and what they use feels like something quietly slipping away.
This guide is for you. It covers what heritage language actually is, why NRI families specifically face this challenge at a structural level, what the research says, and what you can do starting today.
What is a heritage language, and why does it matter more than you think?
A heritage language is any language that connects a person to their family, cultural history, and ethnic identity even if they are not fully fluent in it. For NRI families, this is typically the language your parents or grandparents brought from India: Hindi, Tamil, Punjabi, Bengali, Gujarati, Marathi, Telugu, Kannada, Malayalam.
It is not just a communication tool. Researchers increasingly describe heritage languages as an identity anchor, the thread that connects a child growing up in Leeds or New Jersey to a grandmother in Kochi or Chandigarh. When that thread breaks, what breaks with it is harder to quantify: the ease of extended family relationships, the cultural self-knowledge, and the sense of belonging to something older and larger than a single postcode.
Why is heritage language for NRI families harder than it looks?
NRI parents who struggle to pass on their heritage language are not failing. They are up against forces that are structural, not personal. Understanding the actual mechanism helps enormously.
The volume problem
Your child spends six to eight hours every school day in an English-medium environment, absorbing English through instruction, friendships, sport, media, and social belonging. By the time they get home, English is not just a language. It is the default mode of thought. Research published in peer-reviewed bilingualism journals has consistently shown that children between ages six and ten undergo phases of linguistic convergence, gravitating toward whichever language dominates their social environment.
The shame mechanism
Heritage language researchers have identified shame as one of the most powerful drivers of language abandonment in children of immigrants. A single incident, being laughed at by a relative for a mispronunciation, or corrected harshly in front of peers, can trigger years of resistance. What looks like stubbornness from the outside is often a child protecting themselves from the memory of humiliation.
Research note: emotional stressors specific to heritage learners
A 2024 study published in the International Journal of Bilingual Education and Bilingualism documented that heritage language learners experience distinctive emotional stressors, including shame, frustration, and discomfort, that are qualitatively different from second-language learners. Understanding this distinction changes how parents and tutors approach the experience.

The "enough at home" trap
Most NRI parents assume that being spoken to in the heritage language at home is sufficient. Research consistently shows it is necessary but not sufficient. Children develop active speaking ability through communicative necessity. They need real, meaningful reasons to use the language. Passive exposure builds receptive ability, understanding, but not productive ability, speaking. This is why so many second-generation NRI children understand everything but respond only in English.
What does the research actually tell us about heritage language and NRI children?
Mental health and behavioural benefits
A peer-reviewed study published in the Journal of Youth and Adolescence (University of Turku, 2023) found that speaking the heritage language within immigrant families is associated with improved behavioural and mental health outcomes in children, particularly when family relationships are warm and cohesive. Heritage language use was linked to fewer internalising problems such as anxiety and withdrawal, and fewer externalising problems such as conduct issues.
Identity, self-esteem, and belonging
Research published in the UK on heritage bilingual students across first and second generations found clear links between heritage language proficiency, stronger heritage identity, and improved psychological wellbeing. Students with higher heritage language use reported more bicultural orientation, the ability to hold both identities simultaneously, which is associated with lower rates of identity conflict and higher self-esteem in diaspora youth.
The family language policy finding
A 2025 study in Frontiers in Psychology examining heritage language maintenance across transnational families identified multigenerational family structures, cultural practices, and positive family experiences as the strongest enablers of heritage language transmission. Critically: intentional, empathetic engagement, not enforcement, was consistently linked to positive outcomes. Families who made language learning warm and cultural retained it. Families who made it obligatory frequently lost it by the second generation.
Which heritage languages are most at risk?
Here is the honest picture, language by language, for the diaspora communities Hindustani Tongue works with every day.

The Iyer family, Leicester: from refusal to fluency in 8 weeks
Real stories show what the research looks like in practice. This one is typical of the families we work with, in structure if not in detail.
A nine-year-old who understood everything and said nothing
Priya Iyer, a second-generation Tamil speaker, moved from Chennai to Leicester in 2009. Her son Arvind was born in the UK. By age nine, Arvind understood conversational Tamil but flatly refused to speak it, switching to English mid-sentence even when his grandparents called from Chennai.
The root cause was identified quickly. Two years earlier, a relative had laughed at Arvind's mispronunciation of a Tamil word during a family wedding video call. He went silent and never tried in front of family again.
Hindustani Tongue matched Arvind with a Tamil tutor who shared his love of cricket and began sessions with match commentary in Tamil. Low stakes, topic-led, no formal corrections mid-conversation. The first three sessions covered zero grammar.

What can NRI families actually do? A practical framework
Stop thinking of heritage language as a subject to teach. Start thinking of it as a relationship to build. These approaches consistently work.
Make the language the language of affection, not instruction
Use your heritage language for warmth, such as "come here," "I love you," "are you hungry," or "let me tell you something funny," not just for chores or instructions. Children absorb languages that are emotionally salient. When Tamil or Punjabi becomes the language of comfort and closeness, the motivation to speak it follows naturally.
Create communicative necessity, not obligation
The greatest predictor of heritage language retention is whether the child has a real reason to use it. Weekly video calls with monolingual grandparents. A trip to India where only the heritage language is spoken. A cousin who does not speak English. Research from the University of Edinburgh found that children with regular contact with monolingual extended family retain their heritage language at significantly higher rates.
Use the One Parent, One Language method (OPOL)
If both parents share a heritage language, speak it consistently at home. If each parent has a different heritage language, each parent speaks their own always. The OPOL method is one of the most widely researched strategies in bilingualism science and shows consistent positive results when applied from early childhood.
Never shame. Correct gently, once, later
Shame is the most documented cause of heritage language abandonment in NRI children. One harsh correction in front of family members can silence a child for years. When your child speaks, even broken, even mixed with English, celebrate the attempt. Correct quietly, once, at the end of a conversation, never mid-sentence.
Use media as a bridge, not a replacement
Hindi cartoons, Tamil YouTube channels, Bengali audiobooks, Punjabi music, all genuinely useful, especially for vocabulary. But passive media alone does not build speaking ability. Co-view: watch together for 20 minutes, then discuss what happened in the heritage language for five minutes. That conversation is worth more than two hours of passive watching.
Bring in a native expert tutor
Home effort is essential, but it hits a ceiling. Parents are not language teachers. A structured programme with a trained native tutor who specialises in heritage learners changes what is possible. At Hindustani Tongue, children as young as five learn through live 1-on-1 sessions with tutors who specialise in exactly the challenge NRI families face.

The moment that makes it all worth it
There is a specific moment that Hindustani Tongue tutors talk about among themselves. It happens around the sixth or seventh week. A child who came in quiet, giving one-word answers with arms figuratively crossed, suddenly starts a sentence in Tamil. Or Punjabi. Or Bengali. Not because they were asked to. Just because the thought came out in that language.
One tutor described it as watching a door open from the inside.
We had a nine-year-old in Brampton, Ontario, a second-generation Gujarati girl named Ishika, who had not spoken Gujarati to her grandmother in two years. By week six of her sessions, she was calling her Dadi in Surat to tell her about her school project. In Gujarati. Without being told to.
That is not just a language milestone. That is a child choosing her roots. That is a connection repaired across 12,000 kilometres.
Your child's heritage language is not lost. It is waiting.
