Extremely LowHighly Specialized, Academic, Technical
Definition
Meaning
A constructed language developed for non-human primate research, using lexigrams (symbols) on a keyboard.
Any symbolic, pictographic communication system designed for non-human species, particularly apes, to communicate with humans. It is also used as an adjective to describe something related to this language system (e.g., Yerkish lexigram).
Linguistics
Semantic Notes
The term is almost exclusively used within the fields of primatology, cognitive science, and animal language research. It is a proper noun derived from the name of the research center (the Yerkes National Primate Research Center) and thus often capitalized. Outside of this niche, it is virtually unknown.

Examples
By Part of Speech
adjective
British English
- The bonobo used a Yerkish keyboard to make requests.
- Research focused on the apes' Yerkish vocabulary.
American English
- The chimpanzee responded using the Yerkish lexigram board.
- They analyzed the Yerkish language data from the project.
Examples
By CEFR Level
- Scientists taught the ape to use Yerkish.
- The Yerkish language, developed at the Yerkes center, uses symbols called lexigrams.
- Early experiments in ape language relied on systems like Yerkish.
- Critiques of the Yerkish research often focus on the interpretation of the primates' symbolic productions.
- The bonobo's proficiency with Yerkish lexigrams challenged traditional views on animal cognition.
Learning
Memory Aids
Mnemonic
Think of 'Yerkes' (the primate center) + '-ish' (like a language, e.g., English). 'Yerkes-ish language' becomes Yerkish.
Conceptual Metaphor
LANGUAGE IS A TOOL (for bridging species).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with the Russian word "ёрничать" (to joke, to mock). They are completely unrelated.
- It is a proper noun/technical term, not a common adjective.
Common Mistakes
- Using it as a common noun without capitalization (incorrect: 'yerkish'; correct: 'Yerkish').
- Assuming it describes a human language or dialect.
- Mispronouncing it (it is not 'yer-kish' with a hard /k/; the first syllable rhymes with 'fur' or 'sir').

FAQ
Frequently Asked Questions
No, it is not a human language. It is a constructed symbolic system (using lexigrams) designed for research into non-human primate communication.
It is named after the Yerkes National Primate Research Center in the United States, where this communication system was developed.
No, Yerkish is not a spoken language. It is a visual, symbol-based system where users (typically apes) press keys with abstract symbols (lexigrams) on a keyboard or board.
While the original Yerkish keyboard experiments were prominent in the late 20th century, the term is now used historically and in academic literature to refer to that specific system. Modern ape language research may use computerized symbol systems descended from or inspired by it.
