English also holds onto gender for some French loan words (fiancée, blonde), accent marks, Latin plurals (cacti), the Latin notion of the word (viruses because viri is bad Latin), and occasionally Latin gender and plural (dominatrices). But not Greek plurals, so it's octopuses, not octopodes.

With the exception of (one) phenomenon, (many) phenomena, hopefully?

Also, now that I think of it: pegasus/pegasi, prolegomenon/ prolegomena, lemma/ lemmata, schema/ schemata, etc etc. There's one ending in -omenon that I keep forgetting...

As far as I can tell, the English rule is "sometimes we take the loanword's pluralisation, sometimes we don't, just memorise every single case and don't worry if you get it wrong sometimes"

For example, Samurai and Kimono are both loan words - but we import the pluralisation of Samurai (Seven Samurai) [1] whereas Kimono pluralises with an s on the end (Seven Kimonos) [2].

"Criterion/criteria"

Thank you! Yeah, that's the one I keep forgetting, though it doesn't end in "omenon".

[blackshaw]

Another one I just remembered: "automaton/automata".

This site lets you search for English words by suffix, and the only words it can find ending in "-omenon" are "phenomenon" and... "superphenomon". What a phenomenal result.

IIRC, octopus, while Greek in origin, came into English mainly through scientific Latin, which probably plays a role in it not having a Greek-derived plural, or at least not dominantly (you will encounter both octopi and octopodes in English sometimes.)

Though Australia is in the antipodes (to the UK), not the antipuses.
