"Ce" is a French demonstrative pronoun that translates to "this" or "that" in English. It is used to refer to a specific object or idea that is either nearby or has been previously mentioned. In French, "ce" can also be used in expressions like "c'est" (it is) to introduce or define something. In addition to its use as a pronoun, "Ce" can also refer to the Celsius temperature scale, which measures temperature in degrees. The scale is widely used around the world for everyday temperature readings, especially in scientific contexts.
