I would like to add the English pronunciation of C to this page. It has been uploaded as the file Media:En-us-c.ogg

The link should look like: * {{audio|en-us-b.ogg|Audio (US)|lang=en}} e.g.:

Rfv-sense: the English sense "(physics) The speed of light as a unit of speed, exactly 2.99792458 × 108 m/s." This is defined as a noun, distinct (but apparently derived) from the translingual symbol sense. This would presumably need citations of the form "a c" or "the c", which seems unlikely. -- Liliana 19:43, 4 September 2015 (UTC)

Why does it need that type of citation? Why wouldn't "e = mc2" be a citation? or "greater than c? DCDuring TALK 03:42, 5 September 2015 (UTC)
I would understand those to be using the translingual symbol and not a separate English form. Equinox 03:45, 5 September 2015 (UTC)
That just says that we need cites in other languages. I'd be surprised if we couldn't get them in every language in which physics is taught. DCDuring TALK 03:56, 5 September 2015 (UTC)
I don't understand your argument... Equinox 18:45, 8 September 2015 (UTC)
If x = y, don't x and y have to be nouns or pronouns? Conversely, since c is equated with "the speed", and "speed is a noun, doesn't c have to also be a noun? Purplebackpack89 04:48, 5 September 2015 (UTC)
Not in the context of equations, which aren't grammatical sentences. -- Liliana 08:52, 5 September 2015 (UTC)
No it would be possible to use c as a symbol rather than as a noun; 'greater than c' is debatably a use of the symbol c, not a noun c. Renard Migrant (talk) 13:22, 6 September 2015 (UTC)
But in the phrase "greater than c", c must represent something that is a noun. Purplebackpack89 19:17, 8 September 2015 (UTC)
Yes, isn't this a lot like the drive to change "initialism/abbreviation" headers (e.g. km for kilometres) into nouns? Why don't we do that with symbols? Equinox 19:23, 8 September 2015 (UTC)
  • I believe Liliana's interpretation to be correct, and it seems that there are no citations that distinctively use it as English, so this is RFV failed. —Μετάknowledgediscuss/deeds 22:47, 14 February 2016 (UTC)
