Mother Tongue vs Native Language: What Is the Difference?

Mother tongue vs native language confuses many people, but the gap is small.

What Is a Mother Tongue?

A mother tongue is the first language a person learns from their parents or family at home.

It is the language of lullabies, bedtime stories, and first words. Experts also call it a home language or first language.

In the USA, a child in a Spanish-speaking home has Spanish as a mother tongue, even if school is in English.

What Is a Native Language?

A native language is the language a person picks up naturally in early childhood, without formal lessons. It comes from family, but also from the community and surroundings. It is also called a native tongue.

• Natural fluency without effort
• A strong instinct for correct grammar
• Easy use of idioms and slang
• A familiar accent and tone

Native Language vs First Language

In most cases, native language and first language mean the same thing. Both point to the language a person learned first in life.

The word “native” adds a sense of belonging, while “first” only shows order. Researchers often use L1 to keep things simple.
