chi

This term refers to a metaphysical concept of life force rather than a physical substance. It is used primarily within the contexts of traditional Chinese medicine, martial arts, and spiritual practices like qigong or tai chi. The term carries a connotation of harmony and balance, where health is viewed as the result of the unobstructed flow of this energy.

As an abstract concept representing a universal energy, the word is treated as an uncountable noun. It does not have a plural form and cannot be quantified with numbers; instead, it is described in terms of quality, strength, or flow.
