Fungi, termini, stimuli

Fungi, termini, stimuli
 

are these words pronoundec with i or ai. Terminai? or temini?
fungai or fungi, stimulai or stimuli?:rose:

Always with the i as in high or eye. Also Goodbye :D

What is "Termini?" I looked it up in the dictionary (english and spanish) but could not find it.

Most English words ending in -us are second declension Latin ones (e.g. terminus) which have a plural in -i. Some are Latin 3rd declension neuters, e.g. corpus - corpora, and many are 4th declension, e.g. prospectus, prospectuses. Anybody who doesn't know this is in danger of being called an ignoramus, and on this basis just about the whole population are ignoramuses (ignorami :?:). The whole question of English plurals from Latin and Greek could take up the many forums, or even fora.:thinking::D

Brilliant explanation, bravo.

:duh: I should have looked at the other two words to figure it out. Thanks for the explanation. There is always something to learn.

Yup.
