Beyond the definition
Chi has two common English senses. First, it is the 22nd letter of the Greek alphabet (Χ, χ), often pronounced "kye" (/kaɪ/) in English academic usage (pronunciations vary). You see it in terms like chi-squared () in statistics. Second, "chi" is a common English spelling for Chinese qi (often written ch'i in older transliteration systems), the concept of vital energy in traditional Chinese philosophy and medicine, usually pronounced "chee."
So context matters: in math class, chi is usually a Greek letter/symbol; in wellness or cultural discussion, it often refers to life energy (qi).
In English reference works, chi is primarily the name of the 22nd Greek letter, written uppercase Χ and lowercase χ. It is widely used as a symbol in technical fields. In statistics, for example, denotes the chi-square statistic and chi-square tests. In other scientific writing, chi may appear as a variable or parameter depending on the discipline.
A secondary but very common usage is chi as an English spelling for Chinese qi (气 / 氣), referring to vital force or life energy in traditional Chinese thought. This spelling is especially common in popular writing and in older transliteration systems (often written ch'i). In that sense, it appears in contexts such as Tai Chi, qigong, acupuncture theory, and Feng Shui.
Because these are distinct senses with different pronunciation habits ("kye" for the Greek letter in many English academic contexts, "chee" for qi-related usage), clear context is important for learners.
