 For example, the Portuguese word is descended from Latin "window" (and is thus cognate to French , Italian , Romanian and so on), but now means "skylight" and "slit".Cognates may exist but have become rare, such as in Spanish, or dropped out of use entirely.The Spanish and Portuguese terms meaning "to throw through a window" and meaning "replete with windows" also have the same root, but are later borrowings from Latin.
