Banana is obviously a vocabulary of tropical African atmosphere, but the word appears in the fruit world and included in English after a wandering process.
Banana, apparently a word from one of the languages of the Congo area (it has been speculated that it derives ultimately from Arabic banana ‘finger, toe’, an origin which would be echoed in the English term hand for a bunch of bananas, and serves as a reminder that many varieties of banana are quite small, not like the monstrous articles standardly imported into Britain).
Banana 一词明确的源于刚果地区的一种语言，人们推测最初是源自阿拉伯语的 banana 一词，指“手指、脚趾”。这一推测起源也呼应了英语短语 a bunch of bananas / 一把香蕉，也提醒了人们，大多数品种的香蕉都很小，并不像现在进口的巨型香蕉一般。

The colloquial use of bananas for ‘mad, crazy’ is a surprisingly recent development. There is an isolated record of it from the US in the 1930s meaning ‘sexually perverted, degenerate’, but the current usage seems to have originated in US college slang of the mid to late 1960s. It is not clear how it arose. Some connection has been suggested with the earlier slang term banana oil ‘nonsense’, which dates from the 1920s, but since the origins of that too are unknown, the suggestion only pushes the mystery one stage further back.
