Talk:Chi (letter)

Untitled
Any reason this is at Chi (Greek letter) rather than Chi (letter) (which is just a redirect to here), unlike every other Greek letter? Assuming no objections, I'd like to move it for consistency's sake. -- DrBob 18:04, 2 September 2005 (UTC)

Pronunciation - something is wrong here

 * ... it is pronounced like the German ach-laut (/χ/) or in Scottish 'loch'.
 * ach-laut: Voiceless velar fricative
 * /χ/ (notice the uppercase): Voiceless uvular fricative.

Now what is the correct consonantal sound? --Abdull 17:29, 2 June 2006 (UTC)


 * I believe there's variation in German, and perhaps also in Greek, between [x] and [χ], depending on dialect. --Ptcamn 17:48, 2 June 2006 (UTC)

16 YEARS HAVE PASSED AND NOBODY INSERT THE CORRECT PRONUNCIATION; PLEASE REMOVE THE WRONG PRONUNCIATION AT LEAST. --AlexanderFreud (talk) 16:20, 24 November 2022 (UTC)

Usage
isn't X (Chi) used in XoXoXo (-> Kiss Kiss Kiss) ? (not a rhetorical question, I'm French) -- 10:00, 30 June 2006 (UTC+2) It's not really the point... Wikisquared 10:23, 2 September 2006 (UTC)
 * Yes, kissing the sign of the Cross when swearing an oath, or 'signing' your name if you can't write. Now thought to be an ex. Worthwhile adding. kwami (talk) 10:00, 27 November 2007 (UTC)
 * Should be added to Hugs and kisses as well iff there's a good source. X please, we're French.--87.162.33.234 (talk) 08:22, 14 April 2010 (UTC)

Also, in chemistry isn't lower case chi used to denote "mole fraction?" It would seem appropriate this be included in the article. In a chemistry book I have on hand, ISBN-13:978-0-547-16817-3 on page 510 it describes Raoult's Law, which includes mole fraction. Though it may appear to be a fancy looking "X," it is in fact, lower case chi. I think an update would be in order. —Preceding unsigned comment added by 76.233.233.238 (talk) 04:42, 8 January 2011 (UTC)

origin
removed:
 * It was introduced as a variant of Phoenician  (samekh).

No source, and the writer may have gotten confused with the use of either Ξ or Χ for /ks/ in different Greek dialects. (I have heard the idea that both qoppa and phi derived from Ph. /q/, when Archaic Greek split into  and, but not this.) kwami (talk) 09:58, 27 November 2007 (UTC)
 * I think that Chi (, later in Eastern Greek,  in Western Greek) may be variation of Phoenician Kaph ( or ), together with Kappa  because they are smilar in both pronunciation and shape.  Бошко Рињац (talk) 12:40, 8 August 2010 (UTC)

Semi Protection ?!
What sort of vandalism could possibly result in the semi-protection of as dry a subject as a greek letter :D ??
 * Exactly my thought. --82.49.78.25 (talk) 11:57, 10 March 2014 (UTC)

 * Because English commoners pronounce (or mispronounce) the letter as /t͡ʃi/ and to add the alternative pronunciation is too üntermenschy for enlightened and all-knowing Wikipedia admins. 124.169.150.131 (talk) 11:46, 17 January 2021 (UTC)

Exactly. This is so stupid. -Stiabhna (talk) 20:54, 21 December 2021 (UTC)

Susceptibility
In electromagnetism Chi is used to represent the electric and  magnetic susceptibility of a material. This should probably be added to the Math and Science section of the article. I'm not sure of the procedures for editing a protected page so I apologize if this isn't the right place to mention this. Jtst4 (talk) 21:28, 10 August 2017 (UTC)

ch sound
Does Greek have the sound tʃ (China, catch). Did Ancient Greek? Roman? MBG02 (talk) 17:48, 16 November 2018 (UTC)

Greek has never had tʃ, ʃ, dʒ or ʒ. 147.147.123.224 (talk) 16:27, 11 December 2022 (UTC)

Dirichlet character
Someone should add to the usage section that it's used for the Dirichlet character in number theory. 86.130.89.208 (talk) 01:48, 24 April 2022 (UTC)
