Deepfake is a noun that refers to an image or recording altered to misrepresent someone. 

A recent addition to the English language, our word of the day is derived from two common words of Old English origin, ‘Deep’ and ‘fake’ and describes a practice that has only become possible in the past few decades. Here’s an example:

That deepfake of my favorite actor looked so convincing I nearly believed they were preparing to star in a new production. But I soon realized they were being misrepresented when they claimed to be staring in a new production on the moon.
