Sunbrella

Sunbrella: noun. According to the Movement for the Rationalisation of the English Language, a sunbrella is an object used to shield oneself from the sun, but is not a parasol. The main difference between the two, as Lewis Carroll pointed out, is that a sunbrella simply isn´t a parasol and a parasol is not a sunbrella. Because of the similarity of the two objects (which Carroll never saw), one term for them eventually had to drop out of common usage and, sadly, it was not the word "parasol," which sounds completely un-English and even has the foreign words "para" (for) and "sol" (sun) within itself.
