means A collapsible canopy on a folding frame, carried by hand to shield you from rain or sun.

from From the Italian 'ombrella,' a diminutive of 'ombra,' meaning shade — itself from the Latin 'umbra,' shadow. So the word was born for sun, not rain: a little patch of portable shade. The rain-fighting career came later, especially in damp northern climates where the same device found a soggier purpose. That Latin 'umbra' also casts a long shadow elsewhere — it's a cousin of 'umbrage' and 'penumbra.'
