tulipo

A flower named after a hat. The story is unusually well documented for an etymology. Europeans meeting the flower at the Ottoman court in the 1500s asked what it was called and came away with tülbend, the Turkish word for a turban - either because the bloom looks like one, or because of a misunderstanding about what exactly was being pointed at. Nobody has settled which. The name stuck across a dozen languages, and the same Turkish word walked into English by a different door as turban. Say tulipo and turbano next to each other and you can hear the family resemblance that four hundred years of separate travel did not quite erase.

Everything after that is Dutch. The bulbs reached the Low Countries in the 1590s, and by 1637 a single rare bulb could be priced against a house - the episode still cited as the first speculative bubble in recorded economic history.

Using it. Tulipo is the flower, tulipbulbo the bulb, tulipkampo a tulip field. Like every plant name in Esperanto it takes the ordinary -o and behaves as an ordinary noun; there is no botanical special case in the grammar.
