Nirth: English is my second language, maybe it could affect how one would view the difference, but I would pick zeroth before nought because the former sounds like a word, the other sounds like gibberish or a poor version of 'naughty'. I would also put 'nought' closer to nothing rather than zero, sort of like the mathematical difference if I remember correctly.
SirPrimalform: Naught only means nothing, but nought does also mean the number (at least in the part of the UK I live in). They're obviously the same word in terms of etymology and are pronounced the same but somehow the meanings have diverged subtly. I'm familiar with 0th as a concept, but it's only when seeing it in a title that I realised I'd never tried pronouncing it and zeroth (which is apparently the standard pronunciation sounds really awkward to me).
Noughth sounds like a reasonable word to me, but it could be because I'm used to hearing nought to mean 0 (not to mention other contributing factors like my accent and so on).
Azilut: Mortal tongues cannot pronounce it. Terrible things would happen if they did!
SirPrimalform: Will Zeroth the Unforgivable be summoned again?
JudasIscariot: Zeroth was actually used by Isaac Asimov in one of his stories about robots and the laws that govern them :)
http://en.wikipedia.org/wiki/Three_Laws_of_Robotics SirPrimalform: That's what he gets for painting himself into a corner and then realising that there's one even more important than the first. ;)
Is the name 'nought' used at all in US English? I'd guess that there's no other choice if zero is the only name...
I've heard "aught" used to describe the caliber of some shotgun ammo. See the Buckshot section of this wikipedia article:
I don't recall ever hearing nought used for 0 but then again it could be a regional thing and maybe they don't use nought much in the South :)
