Chimpanzees can pick up on some parts of human communication, but they just don’t get language the way we do. They might learn simple signs or symbols to share ideas, yet most of the time, they’re just copying what they see or hear. Creating brand-new sentences? That’s not really their thing.
So, while chimps pick up certain cues, they don’t fully understand human language.
You might be surprised to learn that chimpanzees mix different sounds to send more complex messages within their own groups. This ability offers some hints about how human language got started.
When you watch chimps communicate, you get a peek into the early stages of how language might have evolved. It’s honestly kind of fascinating.
If you’ve ever wondered how close chimps are to speaking like us, or what all this says about where language comes from, you’re not alone. Let’s dig into what chimps can (and can’t) do with human language.
How Chimpanzees Communicate and Their Language Abilities
Chimpanzees use a mix of calls, gestures, and learned symbols to share information. They show off some basic features like combining sounds and following patterns, which gives us clues about how human language could have started.
Chimpanzee Communication Methods
Chimpanzees use sounds, body language, and facial expressions to communicate. In the wild, they make different calls to warn about danger, ask for help, or show excitement and frustration.
You might see them slap tree trunks or drum on objects, which helps them send messages far away. Their faces and body postures add even more meaning.
A smile or a raised eyebrow can show friendliness or curiosity. These signals help chimps build social bonds and work together.
This variety makes their communication pretty flexible—not just a bunch of fixed calls.
Vocalizations and Gestures Among Primates
Wild chimpanzees come up with a bunch of different sounds, and they combine them to change meaning. They use around 16 two-call combos, kind of like putting simple words together.
You’ll hear pant-hoots, screams, and grunts, each with a different meaning based on what’s going on. Gestures like arm raises, pointing, or touching also help them get their point across.
These non-verbal moves let them express needs or persuade others. When you add up the sounds and gestures, you get a pretty complex system—almost like a rough draft of language.
Use of Sign Language and Lexigrams
Some chimpanzees who grew up around humans have picked up parts of American Sign Language (ASL) and learned to use lexigrams—those symbols on keyboards that stand for words.
You might know about Washoe or Kanzi, those famous chimps who understood hundreds of signs or symbols. They could even string them together to make simple requests.
They don’t really master grammar, though. Still, their use of ASL and lexigrams proves they can communicate beyond just natural calls.
This skill lets researchers see just how close chimps can get to our kind of language.
Studies on Syntax and Rule-Based Communication
Researchers have found that chimpanzees can combine calls in ways that follow simple rules—kind of like syntax in our language. They can change the order or mix calls to tweak the meaning, using two-call combos to warn about different dangers.
This challenges the old idea that only humans use rule-based communication. Chimp syntax is way simpler, but it hints that the roots of human language might come from our shared ancestors.
Primates clearly have some ability to structure messages, even if it’s not as advanced as ours.

Limits of Chimpanzees’ Understanding of Human Language Compared to Humans
Chimpanzees impress us with their communication skills, but there’s a ceiling to how much human language they really get. These limits come from how they learn, what famous chimps have shown us, and what scientists think about language evolution.
Differences From Human Language Acquisition
When you learn language as a kid, you naturally pick up sounds, words, and grammar. Your brain forms deep connections, and your vocal system is super flexible.
Chimpanzees don’t learn language this way. They can pick up signs or symbols, but mostly by copying or responding to cues.
Humans use syntax, or word order, to create endless meanings. Chimps can combine signs, but they don’t build new sentences with grammar.
Their vocal cords also make it tough to produce many of our sounds. So, chimps’ language learning is mostly imitation, while humans invent and understand complex, changing language.
Notable Language Experiments With Washoe and Nim Chimpsky
You might’ve heard about Washoe, the chimp who learned over 100 ASL signs and used them to share basic ideas. Then there’s Nim Chimpsky, who was part of a big study to see if chimps could pick up grammar.
Nim could copy signs, but he barely ever combined them with real syntax or creativity. Herbert S. Terrace, who ran Nim’s study, argued that Nim mostly used signs to ask for things or copy people—not real language.
These experiments show that chimpanzees can learn some forms of communication, but they just don’t have the full range of human language skills.
Scientific Perspectives and the Role of Noam Chomsky
Noam Chomsky, a huge name in linguistics, claims human language comes from a unique “universal grammar”—a mental ability chimps just don’t have. He says we’re born with this skill to learn and use complex language structures.
Chimpanzees don’t show signs of this special grammar ability. Most scientists agree their brains just don’t have the wiring for true language acquisition like we do.
That helps explain why chimps never develop natural speech or full grammar, even though they’re smart and social.
Implications for Human Evolution and the Origin of Language
Ever wonder why only humans ended up with language, even though chimps share so much with us? Researchers have found that some early vocal abilities and basic communication skills already existed in our common ancestors millions of years ago.
But then, humans took a different path. Our brains evolved in ways that made language possible. For example, we developed larger brain areas like the arcuate fasciculus. This part connects speech production with understanding what others say.
When we look at these differences, it becomes a bit clearer why humans started using spoken and signed languages, while chimps stuck with simpler communication. These clues also help us piece together how language may have kicked off and changed over time as a uniquely human thing.
