A child may speak Spanish with Grandma, hear Polish from Dad, sing songs in Mandarin with Mom, or understand Arabic at home while using English almost everywhere else.
The family language in situations like these is often called a heritage language.
But what makes a language a heritage language? Is it the same as a home language? And does a child have to speak it fluently for it to count?
Understanding these terms can help bilingual families make sense of how their children’s languages develop and why maintaining a family language can matter.
Quick Answer: What Is a Heritage Language?
A heritage language is a language connected to a person’s family, cultural background, ancestry, or community that is used alongside a more dominant language in the society where they live.
In the United States, Spanish, Chinese, Arabic, Polish, Korean, Vietnamese, Indigenous languages, and many others can be heritage languages when they are connected to a person’s family or community background.
A child does not have to speak a heritage language fluently for it to be meaningful. Some children speak their heritage language comfortably, while others understand much more than they can say.
Heritage-language ability can also change over time as a child’s family life, school environment, friendships, and language exposure change.
Key Takeaways
- A heritage language connects a child with family, culture, ancestry, or a linguistic community.
- A heritage language is often spoken at home, but “heritage language” and “home language” do not mean exactly the same thing.
- The community or majority language is the language a child encounters most widely outside the home.
- Children do not have to be equally fluent in two languages to be bilingual.
- A child may understand a heritage language well while preferring to speak the community language.
- Heritage-language ability can become stronger or weaker as a child’s exposure and opportunities to use the language change.
- Maintaining a heritage language can support communication with family, cultural connection, and a child’s developing bilingual identity.
What Makes a Language a Heritage Language?
A language becomes a heritage language because of its relationship to a person, family, or community, not because of anything inherent in the language itself.
Consider Spanish.
For a child growing up in Mexico, Spanish may be the majority language spoken at home, at school, and throughout the community.
For a child growing up in an English-dominant community in the United States with Spanish-speaking parents or grandparents, Spanish may be a heritage language.
The language did not change. Its role in the child’s life did.
Heritage languages can include languages brought by immigrant families, Indigenous languages, and languages that families have maintained across several generations.
The connection can also take different forms. A child might hear the language every day from parents, use it mainly with grandparents, attend a community language program, or be reconnecting with a language that previous generations of the family spoke.
This is one reason bilingualism is better understood as a range of abilities and experiences rather than a requirement to speak two languages equally. Our guide to what it means to be bilingual explores that idea in more detail.
Does a Child Have to Speak a Heritage Language Fluently?
No.
Children can have very different abilities in their heritage language.
One child may speak it easily but have little experience reading or writing it. Another may understand family conversations but answer almost entirely in English. Another may know only certain words, songs, greetings, or expressions associated with family life.
All of these children can have a meaningful connection with a heritage language.
A child also does not have to speak two languages equally well to be considered bilingual.

Heritage Language vs. Home Language vs. Community Language
These terms are related, but they describe different aspects of a child’s language environment.
Understanding the distinction can make many discussions about bilingual development much easier to follow.
| Term | What It Usually Means | Example |
|---|---|---|
| Heritage language | A language connected with family, ancestry, culture, or community | Spanish in a Spanish-speaking family living in the United States |
| Home language | A language regularly used within the household | Parents regularly speak Spanish with their child at home |
| Community language | The language widely used in the surrounding society | English in much of the United States |
What Is a Home Language?
A home language is simply a language regularly used within family life.
It may be the language parents use while playing with their child, preparing meals, giving instructions, reading stories, comforting them, or talking with relatives.
A home language and a heritage language often overlap.
For example, Spanish may be both the heritage language and the primary home language of a family living in an English-dominant community.
But the terms are not interchangeable.
A bilingual family might use both English and Spanish at home. In that situation, both are home languages, while Spanish may be the language associated with the family’s cultural or ancestral heritage.
What Is a Community or Majority Language?
The community language is the language a child encounters broadly outside the home.
It may dominate childcare, school, playgrounds, stores, sports, entertainment, and interactions with other children.
In much of the United States, that language is English.
This broader exposure gives the community language an enormous advantage. A toddler may hear the heritage language regularly at home but encounter English through childcare, friends, television, activities, and nearly every trip outside the house.
As a result, the community language often becomes a bilingual child’s stronger or preferred language over time.
How Does a Heritage Language Become Stronger or Weaker?
Children develop language through meaningful exposure and opportunities to use what they are learning.
A heritage language is more likely to remain strong when children hear it regularly and have genuine reasons to communicate in it.
That can include conversations with parents, playing with other children, talking with grandparents, listening to family stories, reading books, singing songs, and participating in cultural or community activities.
On the other hand, a heritage language can become less active when opportunities to hear and use it decline.
This often happens naturally as children’s lives expand beyond the home.
How Language Exposure Affects Heritage Language Development
Language exposure includes more than the number of hours a child hears a language.
Who speaks it, when they speak it, what they do together, and whether the child has opportunities to respond all matter.
A toddler who hears a parent speak the heritage language during play, meals, stories, and everyday conversation receives a different kind of exposure from a toddler who mainly hears the language playing in the background.
Interactive exposure gives children opportunities to connect words with people, actions, feelings, and experiences.
If maintaining the family language is becoming difficult, How to Increase Language Exposure for Bilingual Toddlers offers practical ways to create more opportunities without completely restructuring family life.
How Language Dominance Can Change Over Time
Bilingual children are not necessarily equally strong in both languages.
One language may become easier to understand, speak, or use in particular situations. This is known as language dominance.
Dominance can change.
A toddler who spends most of the day at home with a Spanish-speaking parent might initially use Spanish most often. After starting an English-speaking preschool, English may gradually become stronger.
School, friendships, reading, media, activities, and family routines can all influence which language a child uses most easily.
This does not mean the child has stopped being bilingual or that the heritage language no longer matters.
Our guide to language dominance in bilingual toddlers explains why these shifts happen and why a child’s dominant language is not necessarily permanent.
Why Do Some Children Understand Their Heritage Language but Rarely Speak It?
This is a very common pattern in bilingual families.
A child may hear the heritage language regularly from parents or grandparents and develop strong understanding. But if English is the language they use at childcare, school, with friends, with siblings, and during activities, English may become easier to speak.
This creates a difference between receptive language and expressive language.
Receptive language is what a child understands.
Expressive language is what a child communicates through words and sentences.
A bilingual child can therefore have strong receptive ability in a heritage language while having much stronger expressive ability in the community language.
That does not mean the child knows nothing of the heritage language. Understanding is a genuine language skill and can provide a foundation for greater speaking ability.
You can learn more about this distinction in Receptive vs. Expressive Language in Bilingual Children.
Why Is Maintaining a Heritage Language Important?
Families have different reasons for wanting to maintain a heritage language.
Some hope their children will become highly proficient bilingual speakers. Others mainly want their children to communicate comfortably with grandparents and relatives.
There is no single language goal that every bilingual family needs to pursue.
Still, maintaining a heritage language can provide several meaningful benefits.
Communication With Family
Language can shape the relationships children are able to build with relatives.
Grandparents, great-grandparents, cousins, and extended family members may be more comfortable speaking the heritage language than the community language.
When children can communicate with those relatives directly, conversations do not have to depend on another person translating.
A child can ask Grandma a question, understand a family story, tell a joke, or explain what happened at school in a language they share.
That ability can become increasingly valuable as children grow older and family relationships deepen.
Connection to Culture and Family Traditions
Language carries more than vocabulary.
It can carry family stories, humor, songs, prayers, sayings, recipes, celebrations, and ways of expressing affection that do not always translate neatly into another language.
Knowing a heritage language can give children more direct access to those parts of family and cultural life.
The goal does not have to be perfect fluency. Even partial knowledge can help a child understand where certain traditions, expressions, and family stories come from.
Bilingual Identity and Sense of Belonging
Language can also become part of how children understand themselves.
A bilingual child may move between a home where one language is important and a broader community where another language dominates.
Maintaining some connection with both can help the child participate in both parts of their world without feeling that one has to replace the other.
This relationship between language, culture, and identity may also change as children grow.
For some children, a heritage language that seemed unimportant during childhood becomes much more meaningful during adolescence or adulthood.
Maintaining Bilingual Ability
Languages need opportunities to be used.
If a heritage language remains part of everyday conversation, relationships, books, activities, and family life, children have more opportunities to continue developing it.
If exposure and use decline substantially, children may gradually become less comfortable speaking it even though they continue to understand much of what they hear.
This is why maintaining bilingual ability is usually less about formal lessons and more about keeping both languages meaningful and useful in the child’s life.
Does Speaking the Community Language More Mean a Child Is Losing the Heritage Language?
Not necessarily.
It is very common for bilingual children to begin using the community language more as they spend increasing amounts of time outside the home.
A child who starts preschool may suddenly have much more English in their day. Later, friends, schoolwork, sports, entertainment, and reading may increase that exposure even further.
The child may begin answering parents in English even when parents continue speaking the heritage language.
This does not automatically mean the heritage language has disappeared.
The child may still understand it very well while finding English faster or easier to speak.
Over longer periods, however, a heritage language can become weaker when a child has fewer opportunities to hear and especially use it.
Instead of focusing only on which language your child chooses most often, look at the broader pattern.
Can your child still understand everyday conversations in the heritage language?
Can they communicate with relatives?
Are they continuing to learn new words?
Do they sometimes use the language spontaneously?
Has their ability been gradually increasing, remaining stable, or noticeably declining?
These questions tell you more than whether your child happened to answer you in English today.
How Can Families Help Maintain a Heritage Language?
Maintaining a heritage language does not require turning your home into a classroom.
For young children especially, language develops through relationships and ordinary life.
Families can support a heritage language by:
- using it regularly during everyday routines
- reading and singing in the language
- connecting children with grandparents and other speakers
- creating opportunities to play with children who use the language
- making books and age-appropriate media available
- including the language in celebrations and family traditions
- giving children genuine reasons to communicate rather than constantly testing their vocabulary
Most importantly, try to make the language something your child associates with people, relationships, enjoyment, and belonging.
If your toddler understands the language but increasingly responds in English, How to Encourage Your Bilingual Toddler to Speak the Home Language provides more specific strategies for encouraging speech without turning the language into a source of pressure.
Final Thoughts
A heritage language is more than simply the “other” language a bilingual child hears.
It can connect a child with parents, grandparents, extended family, cultural traditions, and a larger part of their identity.
Children do not have to speak their languages equally well for both languages to matter. One language may be stronger, and that balance may change many times as a child grows.
For families who want to preserve a heritage language, the most important step is to keep giving that language a meaningful place in everyday life.
A language is much easier to carry forward when a child has people to speak with, reasons to use it, and relationships that make the language worth keeping.
Frequently Asked Questions
What Is an Example of a Heritage Language?
A child living in an English-dominant part of the United States whose parents or grandparents speak Spanish may have Spanish as a heritage language. The same could be true of Arabic, Polish, Korean, Vietnamese, Mandarin, an Indigenous language, or many other languages.
What makes it a heritage language is the child’s family, cultural, ancestral, or community connection to it.
Is a Heritage Language the Same as a Home Language?
Not always. A home language is a language regularly used within the household. A heritage language is connected with a person’s family, culture, ancestry, or community.
The two often overlap. For example, Spanish could be both a child’s home language and heritage language, while English is also used at home.
Can English Be a Heritage Language?
Yes. Whether a language functions as a heritage language depends on the family and surrounding linguistic environment.
English is the majority language in much of the United States, so it is not usually described as a heritage language there. But a family living in a country where another language dominates could maintain English across generations as a heritage language.
Can a Child Have More Than One Heritage Language?
Yes. A child can have connections to two or more heritage languages through parents, grandparents, extended family, or cultural communities.
For example, one parent might speak Spanish and another Korean while the child grows up in an English-dominant community. Both Spanish and Korean could be heritage languages for that child.
Does a Child Have to Speak a Heritage Language to Be Bilingual?
A child does not need equal speaking ability in both languages to be bilingual. Some bilingual children understand a heritage language very well but speak the community language much more often.
Bilingual ability can look different across understanding, speaking, reading, and writing, and those abilities can change over time.
