/A minor comment: //
//The correct plural form of "topos" is "topoi", as the plural form of
"logos" is "logoi". I vaguely remember that the plural form of "topos"
was already discussed on this board. //
/ /
//In ancient Greek, "(ho) topos" is a noun. Here is a citation: "Ton de
hyperouranion topon ..." //
//(Plato, Phaidros, Bibliotheca Oxoniensis, Tomus II, 247 c). This
citation shows that "topos" is a noun. /
If we were doing category theory in Classical Greek, this argument would
be irrefutable. The claim that it's a noun is, of course, irrefutable
anyhow.
Embedded in an English sentence, however, "topos" is, a loan word, and
the pluralization of loan words is inconsistent. (We also don't decline
them.. or we'd be stuck with topou theory!)
"Duck-billed platypodes," anybody?
Cheers,
Robert

I would like to add that the correct plural of "color" is "colores".
Because as everybody knows, "color" is a Latin noun. For example, here
is a citation: "Omnes vero se Britanni vitro inficiunt, quod caeruleum
efficit colorem, atque hoc horridiores sunt in pugna aspectu" (Caesar,
Commentarii de bello Gallico, Liber V.14.2)". Proving that "color" is
a noun. Therefore, I urge everyone to use "colores" instead of the
incorrect "colors" (or worse, "colours")! -- Peter

The mathematical word "topos" is not taken from Greek, but from French as a
back formation of "topologie." The French plural is "topos," and the
English analogue is "toposes." Etymology is always interesting.

That is, of course, one view on the matter. I'd always inclined to the Gre=
ek plural, but Peter Johnstone famously asked whether those of us who take =
that view when going out on rambles carry our supplies of hot tea in thermo=
i, and I think I have acquiesced to his point of view.
Maintenance of the root-language plural in English in preference to simply =
adding -s or -es (as appropriate) is much stronger for words from Latin tha=
n from Greek, so the appeal to the fact that the Latinate plurals of axis, =
simplex, (but not complex), and locus are maintained isn't that strong an a=
rgument. Using the Greek plural also opens up the question of whether it sh=
ould be pronounced with correct Greek pronunciation or in the way Erasmus t=
aught all of northwestern Europe to mispronounce Greek.

Yes, this what ancient Greek would dictate.
However, people have argued convincingly that "toposes" is in fact the form intended by Grothendieck.
See, for example, footnote 4 in McLarty's “The Uses and Abuses of the History of Topos Theory”.
Moreover, the plural form "topoi" is used for too many notions in the humanities (including journal titles). Just try
googling for it. And then google for "toposes", for comparison.
To me, "topoi" is the plural form for the notion from rhetoric and "Literaturwissenschaft":
