I beg to differ sirrah. Forget the phonetics for a minute. Susbees had written nucleuses (implying plural).I had responded with nuclei. The furthest I got in Latin was amo, amas, amant.Wrong again keithgrimes.
They' as in the plural, would be nuclei.
One, as in it is a nucleus.
From mensa, mensae (table, in latin) or something similar, bellum, bella (war) and I can't remember the 'us' and 'i' nouns (was it villus and villi?). Such a long time ago when I was 'teached sum latin'.
Sorry to be pedantic but as phonology is my field, the vowel in "buck" would make the pronounciation "nuckleus. Surely no-one would pronounce it this way.I think this really depends on what part of the country you come from as in the long vowel sound in book or shorter sound by the southerner as in 'buck'!
