BORN TO
SPEAK
Unit 2 Lesson 2
Understanding the Nativist Theory
of Language Acquisition
THINK ABOUT THIS
• Think about this: A baby is born
and, within just a few months, they
start making sounds.
• By age two, they start forming
sentences—even if no one formally
"teaches" them grammar!
• How does this happen? Is it just
listening and copying, or is
something deeper at play?
THINK-PAIR-SHARE
Turn to the person next to you and
discuss:
• How did you first learn to speak?
• Do you remember being “taught”
grammar rules, or did you just start
speaking?
THE • The Nativist Theory (also called the
Innateness Hypothesis) states that
NATIVIST humans are born with the ability to
THEORY learn language.
• The ability to speak and understand
language is hardwired into the
brain—just like breathing!
• This idea was introduced by Noam
Chomsky, a famous linguist.
THE LANGUAGE
ACQUISITION DEVICE (LAD)
• Chomsky proposed that every
human has a built-in tool for
learning language called the
Language Acquisition Device (LAD).
• The LAD is like a mental “software”
that helps babies quickly recognize
patterns in speech.
• It allows them to understand
grammar rules even if no one
explains them!
EVIDENCE • Speed of Language Learning – Babies learn
language too fast for it to be just copying.
SUPPORTING
NATIVISM • Children Say Words They’ve Never Heard –
Have you ever heard a child say “I goed to
school” instead of “I went”? This shows that
they are not just repeating what they hear—
they are applying grammar rules on their
own!
• Deaf Children Create Language – Even
without formal teaching, deaf children
invent their own sign languages, proving that
the brain is wired for communication.
• Chomsky believed in Universal
UNIVERSAL Grammar (UG)—a set of basic
GRAMMAR
grammatical rules shared by all
languages.
• This explains why all languages have
similarities!
Example: All languages have ways to
express subjects and actions:
• English: “I eat.”
• Spanish: “Yo como.”
• French: “Je mange.”

CRITICISM OF
NATIVISM
Some scientists argue that:
• Social interaction is more important
than an inborn ability.
• The environment plays a major role
in language learning.
• Some languages have structures
that don’t fit Universal Grammar.
