Other forms: shiftings; shiftingly
The word shifting describes something that is taking a new direction either physically or in thought. If you’ve recently decided that the earth may be round, you are shifting from a flat-Earth viewpoint to a round-Earth one.
Shifting can be used in several senses, but the constant in all of them is change and movement. For example, shifting can describe moving earth: it is usually a bad idea to build your house on a plot of shifting land. The word can also refer to something that is regularly changing: Your friend whose favorite music regularly alternates from heavy metal to jazz to Chinese opera? She has a shifting taste in music.
