Step-by-step explanation:
The term for a bonobo who received linguistic attention and consequently developed a remarkable ability to communicate using lexigrams and understand spoken English is language-trained bonobo. Primatologists and linguistic anthropologists like Sue Savage-Rumbaugh have conducted long-term cognitive studies with bonobos, using lexigrams (symbols representing words) printed on a keyboard. Bonobos like Kanzi and Panbanisha have demonstrated advanced cognitive linguistic skills by responding to human speech and generating language through lexigrams.
