Perhaps all the categorists who insist on toposes instead of topoi will teach their lower division students about coordinate axises and look forward to greeting them when they return to the university as alumnuses? (Naturally if they do this they will omit the diaresis from the second o in coordinate.) (Sorry to be contrarian, but I've always been fond of the Greek plural, and the diaresis on the o in co\"{o}rdinate.) Best Thoughts, David Y. On 10 Oct 2007, at 22:04, Robert L Knighten wrote:

Returning to category theory, and topos theory in particular, I can't resist also quoting his guidance on Latin plurals (which surely must apply even more to Greek): "All that can be safely said [regarding whether to prefer or avoid the Latin form] is that there is a tendency to abandon the Latin plurals, and that, when one is really in doubt which to use, the English form should be given the preference."
Having looked at both a few authorities and some publications outside of category theory where the word is used, I am curious if there is any field other than category theory where the plural of topos is not topoi?
