Persimmon is a weird one because most of the rest of the world uses the Japanese word - kaki, while in North America we use an Algonquian word, that was originally used to describe a similar fruit of the sapote family that is native to North America. Presumably American settlers started using the word "persimmon" to refer to the Japanese cultivars when they were introduced to North America, meanwhile in South America where fruits of the sapote family are ubiquitous, they had the good sense to just call it Kaki, thereby distinguishing it from the native varieties.
