(Mysterious question)

I wonder, there is no meaning of "O" (like in other letters)? Samohyl Jan 15:34, 27 Jan 2005 (UTC)

   I infer a desire on the part of SJ to ask a question. But i have no idea what question was intended, nor in what way finds O to be different from (all or some) other letters.

O(1) time?

There isn't anything mentioned on the page about what "O" means with regards to time - for example, saying that something takes O(1) time, or O(n) time, or so on. I'm not sure what this construct is actually called, and even less about what it really means (hence my wanting to look it up in the first place). It would be nice to at least mention this use of O on the page, with a link to the more detailed wiki page on it, whatever it is. :D --Ciaran H 10:47, 15 June 2006 (UTC)

After a bit of research, it seems that this is called Big O notation or Landau notation. I'm going to put a link to the first in the article, but it could probably be expanded. --Ciaran H 10:52, 15 June 2006 (UTC)
My apologies, it's already there. It would be nice to have it clarified though, maybe with an example of O(1) or something in the text to mean constant. --Ciaran H 10:54, 15 June 2006 (UTC)

Examples

If there is anyone out there who knows what half these IPA letters actually mean, post a few examples please. —Preceding unsigned comment added by 121.216.22.235 (talk) 00:08, 9 June 2008 (UTC)

O in old typeface with a dot or diamond in the middle

I often see text that is using an typeface, GothicaBastarda for example, pretending to be old, medieval gothic or satanic, and the O and other characters with round space in them has a dot or diamond in the center. Why is this and what is the dot called? Is this similar to the strike though 0 often used in computing? —Preceding unsigned comment added by 158.143.207.201 (talk) 12:04, 28 November 2008 (UTC)

vocative

I know it's not used much these days (or at least rarely distinguished from oh) but there ought to be some mention of O (always capitalized) as a marker for the vocative case. --Trovatore (talk) 22:55, 6 May 2009 (UTC)

   Inthe interest of reducing the futility of taking talk pages seriously, let me be either the guy who spoils a joke that's too subtle for me to be an insider on, or the malcontent simpleton who won't endorse the universally accepted lies.
   Or for that matter, let me ask:
  • Are you satisfied ignoring colleagues too dim or too reckless to clarify, in discussing the article also known as "Zero", why they would start a discussion here about 3 other seemingly distinct topics Oh, O (which, i doubt not, also covers o), and Vocative case?
No doubt you will infer that i am not satisfied with that. I may create a WP:essay before i shuffle off this mortal coil. Perhaps i'll come up with a better title than WP:Jerzy's Diatribe. But "gang aft aglay".
--Jerzy•t 05:49, 9 October 2017 (UTC)
Hmm! Now i'm too exhausted to figure out how i slipped from 0 to O....

Associated

Does "associated" mean "related"? The word "associated" appears in the "Use in other orthographies" section. Speling12345 (talk) 2:38, 13 December 2013 (UTC)

Afaka and Ol Chiki

Even alphabets that are not derived from Semitic tend to have similar forms to represent this sound; for example, the creators of the Afaka and Ol Chiki scripts, each invented in different parts of the world in the 20th century, both attributed their vowels for 'O' to the shape of the mouth when making this sound.

In Ol Chiki, the letter that looks like O is pronounced /t/. The two for /o/ and /ɔ/ are rounded (like many other letters) but not full circles. —Tamfang (talk) 02:10, 21 August 2023 (UTC)

It's been unsourced since at least 2013, so I've removed it. –LaundryPizza03 (dc̄) 22:49, 24 November 2023 (UTC)
