We all know that there was more than one horcrux, so the word must have a plural form. But, what is the grammatically correct way to spell the term for "more than one horcrux"?

    to be honest, the only reason I asked the question was to create the horcruz tag, which Richard deleted :(

    @KSmarts Wouldn't it be "horcruces" in Latin?

    Break the word down into its prefix/suffix pair and it would be hor - crux, the plural of crux is cruxes or cruces. Commented Mar 25, 2015 at 23:24

    yeah, I don't see how anyone gets "horcri" at all. The singular of horcri would be horcrus.

    @user14111 with Latin loan words in English, it's a toss-up if you use Latin or English pluralization rule. The question was originally a joke -- horcruxes is the right answer because it's in the book and is a legitimate plural -- but Richard's answer is so good I won't want to delete it.

That's a good question. JKR herself doesn't seem to know:

JKR: And did you like the dedication? "You were right all along about 'Horcri'?"

SU: Oh, no!

MA: Oh, Jo!

SU: There's that word!

JN: Nobody would believe me.

MA: Oh, he's never gonna let us--

JKR: So, I did write him a letter. And I did say that, actually, "horcri" is-- I mean, it occurred to me, you know, it really would've been, I think, a more correct plural, but I already had "inferi", and I didn't wanna have too many, umm, you know, Dark Arts weapons ending in "R I", so it was a kind of stylistic choice, really. I like "horcruxes" as a plural. - Pottercast Interview : Part 1, 2007-12-17


JN: Until next time, guys, keep twiddling those dials.

JKR: The next password will be: "Horcri". Pottercast Interview : Part 2, 2007-12-24

However, on her old website she explicity stated that it was Horcruxes. This page was first archived on 2006-06-12, and last archived on 2011-08-06.

Q. Is the plural of 'Horcrux' 'Horcri?'

A. No, the plural of 'Horcrux' is 'Horcruxes', as demonstrated by the eponymous chapter in 'Half-Blood Prince.'
