Talk:That that is is that that is not is not is that it it is

Relevence

This is every bit as relevant as the two pages cited (eg. James while John had had had had had had had had had had had a better effect on the teacher). It needs to be fleshed out a bit, but that's what this community does, isn't it?—Preceding unsigned comment added by Aphisherofmen (talk • contribs)

"That that is is that that is not is not is that it it is is an English sentence demonstrating lexical ambiguity." Is it really a sentence? When punctuation is added in the next paragraph it is shown to be four sentences. --Jon Sangster (talk) 21:40, 15 July 2008 (UTC)

Perhaps phrase? nancy ^(talk) 21:58, 15 July 2008 (UTC)

This _really_ doesn't seem notable enough to have its own page, and this is the first time since the dawn of wikipedia that I have ever held this opinion. It should be among a list of similar phrases, not on a page of its own. 73.4.11.177 (talk) 00:51, 10 March 2022 (UTC)

Commas

I don't know if this is a regional thing, but it seems to me as though none of the commas in any of the examples should be there. Any thoughts?  — TORTOISEWRATH 03:04, 11 January 2013 (UTC)

I think the commas should be there, so it probably is a regional thing. 87.75.117.183 (talk) 19:52, 6 October 2019 (UTC)

Longer version?

There was an old book (the pages crediting the work was lost, so I can't get a citation yet, but it looked to be around the late 80's in paper quality) of puzzles that I found which had a similar puzzle to this, but the solution was even longer. Puzzle: that that is is that that is not is not that that is is not that that is not that that is not is not that that is is that not so so it is Solution: That that is, is. That that is not, is not. That that is, is not that that is not. That that is not, is not that that is. Is that not so? So it is.

If someone can verify this, I'm sure it'll add a bit more content. 50.101.195.98 (talk) 12:42, 4 June 2014 (UTC)

I can't verify the book, but there was a similar version used as a question once in the UK version of UNIVERSITY CHALLENGE (the TV quiz show, pitting teams of 4 students from varying universities against each other.) That version was "THAT THAT IS THAT IS THAT THAT THAT IS NOT THAT IS NOT THAT IS THAT SO THAT IS SO" Which of course can be structure thusly : "That that is that, is that. That that is not that, is not that. Is that so? That is so." Colloquially meaning - "That which is x, is x. That which is not x, is not x. Is that so? That is so." — Preceding unsigned comment added by 158.169.150.9 (talk) 13:40, 25 June 2014 (UTC)

Yet another version appeared in a school grammar book I once saw. "That that is is that that is not is not is not that it it is." The suggested punctuation rendered it as, "That that is, is. That that is not, is not. Is not that it? It is." The triple "is not" makes it appear especially confusing. I delight in showing this puzzle to my friends because it makes me appear far smarter than I actually am. Snezzy (talk) 13:07, 24 November 2018 (UTC)

Yes, that's the version I found in a puzzle book as a child and remember to this day. It's better than the subject of this article for the very reason mentioned. 87.75.117.183 (talk) 19:47, 6 October 2019 (UTC)

Original research?

There are a few sequences of words discussed in this article that are not accompanied by any citations. Unless we can find sources that discuss them, they seem to be original research. I've added an {{original research}} template for this reason. —Mr. Granger (talk · contribs) 05:29, 22 June 2014 (UTC)

I've removed the apparent original research. If reliable sources can be found, please re-add it. —Mr. Granger (talk · contribs) 20:29, 22 August 2014 (UTC)
