	Chi		'''Chi''' ([[uppercase]] '''Χ''', [[lowercase]] '''χ'''; χῖ) is the 22nd letter of the [[Greek alphabet]], pronounced as ˈkaɪ in English.

			==Greek==
			===Pronunciation===
			====Ancient Greek====
			Its value in [[Ancient Greek]] was an aspirated [[voiceless velar plosive\|velar stop]] /kʰ/ (in the [[Western Greek alphabet]]: /ks/).

			====Koine Greek====
			In [[Koine Greek]] and later dialects it became a [[Fricative consonant\|fricative]] along with [[Theta (letter)\|Θ]] and [[Phi (letter)\|Φ]].

			====Modern Greek====
			In [[Modern Greek]], it has two distinct pronunciations: In front of [[close vowel\|high]] or [[front vowel]]s (/e/ or /i/) it is pronounced as a [[voiceless palatal fricative]] [ç], as in [[German language\|German]] ''ich'' or like the ''h'' in some pronunciations of the [[English language\|English]] words ''hew'' and ''human''. In front of [[open vowel\|low]] or [[back vowel]]s (/a/, /o/ or /u/) and [[consonants]], it is pronounced as a [[voiceless velar fricative]] ([x]), as in German ''ach''. Chi is [[Romanization of Greek\|Romanized]] as <ch> in most systematic transliteration conventions, but also sometimes as <h> or <x> in informal practice.

			===Greek numeral===
			In the system of [[Greek numerals]], it has a value of 600.

			===Xi===
			In ancient times, some [[History of the Greek alphabet#Epichoric alphabets\|local forms]] of the [[Greek alphabet]] used the chi instead of [[Xi (letter)\|xi]] to represent the /ks/ sound. This was borrowed into the early [[Latin]] language, which led to the letter X being used for the same sound in Latin, and the modern languages which use the [[Latin alphabet]].

			==Cyrillic==
			Chi was also included in the [[Cyrillic alphabet]] as the letter [[kha\|Х]], with the phonetic value /x/ or /h/.

			==International Phonetic Alphabet==
			In the [[International Phonetic Alphabet]], chi is the symbol for the [[voiceless uvular fricative]].

			==Chiasmus==
			Chi is the basis for the name [[Chiastic structure]] and the name of [[Chiasmus]].

			==Symbolism==
			In [[Plato]]'s [[Timaeus (dialogue)\|Timaeus]], it is explained that the two bands which form the [[Anima mundi (spirit)\|soul of the world]] cross each other like the letter Χ.

			Chi or [[X]] is often used to abbreviate the name [[Christ#.CE.A7\|Christ]], as in the holiday [[Christmas]] ([[Xmas]]). When fused within a single typespace with the Greek letter [[Rho (letter)\|Rho]], it is called the [[labarum]] and used to represent the person of Jesus Christ.

			==Math and science==
			[[Chi-squared\|Chi]] is also frequently used in [[statistics]].

			In [[Algebraic Topology]], Chi is used to represent the [[Euler Characteristic]] of a surface.

			The [[optic chiasm]], an x-shaped connection of the [[optic nerves]] leading to the eye, got its name from the letter chi because of its shape;<sup>[1]</sup> likewise, the shape of the letter chi is the origin of the [[rhetorical device]] [[chiasmus]].

			In [[EN 1993]], an [[European Standard]] for the design of steel structures, the chi character is used as a symbol for the reduction factor for the relevant [[buckling]] load.
