Interesting. I'd like to see an article on why English speakers decided we needed [our own name](http://i.imgur.com/rdGWiBY.jpg
) for pineapples (the etymology seems pretty clear).
In spanish and catalan it's called `piña` and `pinya` (exact same pronunciation as ñ is ny in catalan) because its shape is similar to the `Conifer cone` (called pinya as well) [1].
