Use "gibbon" in a sentence
"Someone yesterday asked (don't know who it was, as it was an anonymous post, though she did say she was from Canada) what a gibbon is - this is not some obscure English quilting term - this is the stuffed toy on Sarah's postcard - it's a kind of monkey with long arms."
"They said, We are interested in gibbon songs because, apart from human speech, these vocalisations provide a remarkable case of acoustic sophistication and versatility in primate communication."
"Of the apes, though many can stand upright, the gibbon is the only one that attempts to walk in this position."
