What does medium mean?
Medium is a versatile word used most often as an adjective for something that is neither very large nor very small, or that lies between two extremes in degree, quality, or amount. A medium-size garment, a medium difficulty, or a medium level of effort are all familiar uses. As a noun, a medium is the material, channel, or setting through which something is expressed or communicated: print, television, and social media are examples. A medium can also mean a means of achieving an aim, such as travel or education. In older and spiritual contexts, the word refers to a person believed to communicate with spirits. The word comes from Latin, where medium means “middle” or “middle-sized,” and its modern sense still reflects that origin. Its usefulness lies in its ability to describe both a measured middle position and the form through which communication takes place.
