Essere (to be) and Avere (to have) are the first two verbs we learn as Absolute Beginners
So the verbs Essere and Avere in English are used like this
ESSERE - TO BE
io sono -I am
tu sei - you are
tui/lei/it e` - he/she is (notice the verb has changed 3 times already am, are, is)
noi siamo - we are
voi siete - you all are
loro sono - they are
example sentences:
I am Italian - Io sono italiano
you are French - tu sei francese
he/she is Australian - lui/lei e` australiano
we are Italian – noi siamo italiani
you all are Italian – voin siete italiani
they are Italian - loro sono italiani
AVERE – (TO HAVE) works the same way.
I have a child - io ho un figlio (pronounced fi-li-yoh)
You have a child - tu hai un figlio
He/she/it has a child - lui/lei/esso ha un figlio
We have a child – noi abbiamo un figlio
You all have a child – voi avete un figlio
They have a child – loro hanno un figlio
These are very simple sentences, but if you have a few Italian nouns up your sleeve, then you can already start to make simple sentences.
