As a word
One is described as a determiner for a countable noun, a pronoun, and a noun (when referring to the number itself). But this seems to be missing the adjective, e.g., as in "number one priority". Thoughts? Polyamorph (talk) 15:11, 4 November 2023 (UTC)


 * In "number one priority", one is not an adjective; it is "number one" that is an adjective phrase that plays the role of an ordinal numeral (almost a synonym of "first"). I believe (I am not a linguist) that in this phrase, "one" is a noun and "number" is another noun used as a qualifier.
 * By the way, it seems that the first sentence of the section is wrong as the use of "one" as a cardinal numeral is certainly the most common usage. In any case,it must be mentioned in the article that, linguistically, "one" is a cardinal numeral. D.Lazard (talk) 15:48, 4 November 2023 (UTC)
 * OK, thanks. I agree, one as a cardinal number should come first. Cheers Polyamorph (talk) 15:56, 4 November 2023 (UTC)

"As a number" and "Mathematics"
These two sections essential deal with the same thing, the properties of 1 as a number. I plan to merge into a single section "In Mathematics", per WP:WikiProject_Numbers. Please let me know if you have any comments before I do this. Polyamorph (talk) 10:34, 15 November 2023 (UTC)


 * Go for it! (just my vote) It looks like math properties are split between the 2 sections, I don't see why they couldn't be merged. Dhrm77 (talk) 15:36, 15 November 2023 (UTC)

Principia Mathematica
On March 16, 2007, added (diff) In Principia Mathematica, 1 is defined as the set of all singletons.. It was unsourced at the time and has remained unsourced since, and I don't think this is true, Principia Mathematica doesn't define 1 in terms of sets. Has this been misattributed? Polyamorph (talk) 05:41, 16 November 2023 (UTC)
 * I have removed this statement for now, once the definition is confirmed here we can incorporate it back into the text. Polyamorph (talk) 09:08, 16 November 2023 (UTC)
 * I agree. Moreover, the assertion and its attribution are certainly both wrong, since the singletons do not form a set, and this was established by the second author of Principia Mathematica (Russell's paradox). D.Lazard (talk) 10:36, 16 November 2023 (UTC)
 * It's only been sat there, misinforming readers, for 16 years! Polyamorph (talk) 10:42, 16 November 2023 (UTC)
