Why is the plural of 'nemesis' "nemeses" and not 'nemesii'?

and how does one pronounce "nemeses" different from "nemesis"?

Nemesis is directly taken from Latin (which borrowed it from Greek). In Latin, almost all words ending in -is have -es as plural form. You will see the -ii plural form only for nouns which end in -ius.

You can hear the difference between the pronunciation here; nemesis rhymes on this and nemeses rhymes on these.

  • Just adding something to the fire: In english you always get the other idioms rules wrong. Némesis is a name, borrowed from Greek. We agree. In Latin, the plural is formed adding an "S". When the last word is a consonant (not S) you can't add an S. The solution is to add "ES" to the end. So, when you have "aguja (needle)" it becomes "agujas (needles)" but when you have "cajón (drawer)" it becomes "cajones (drawers)". Némesis ends in S as singular so in plural does not need an S (language rule). Same as in París, Tenis and Némesis. To change "is" for "es" is nonsensical in Latin and Spanish. – Billeeb Feb 28 '18 at 11:28
