"L'uomo" is an irregular noun when it comes to changing it to the plural form. It isn't very common to see this, but this is just an irregular change that must memorized.
When you say it isn't very common to see, you mean "uomini" right? But why do you say so? Men is a common word. Unless I understood wrong...
You're right in the sense that "men" is a word that is used very often. However, irregular nouns in general are very unusual within the language and are just things that can be learned only by pure memorization.
So, we are people is a wrong answer? Or it can be correct in a right context, using the same sentence?
noi is irrelevant if you have "SIAMO" "noi" is no needed. siamo is already WE ARE
The previous question used 'uomini' as human beings, but in this question it was used as 'men'. With small sentences such as these, is there a way to tell which is being used?
Man is uomo, men is uomini. The O changes to I in the plural context.
"man" is an irregular word it changes to "mEn" in pruler unlike the words when we just add "S"
