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 𐤎‎ (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 /kʷʰ/ split into /kʷʰ/ and pʰ, but not this.) kwami (talk) 09:58, 27 November 2007 (UTC)

I think that Chi (/kʰ/, later /x/ in Eastern Greek, /ks/ in Western Greek) may be variation of Phoenician Kaph (/k/ or /x/), together with Kappa (/k/) 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)

I presume you are fortunate enough not to be familiar with American "Greek" organizations? http://en.wikipedia.org/wiki/Fraternities_and_sororities_in_North_America#Greek_letters 128.193.252.44 (talk) 11:45, 12 December 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)
