What’s the difference between ho cambiato and è cambiato?
- Ho cambiato casa – I’ve changed home (I moved to a different home?
- il clima è cambiato – The climate changed
If you have an eye for details, you have already noticed that the verb cambiare can be used with two different auxiliaries (or helping verbs). Just like in the example above.
In fact, in the first phrase, the verb cambiare uses the auxiliary avere. In the second one, it uses the verb essere.
Now, you might want to know if there is any difference between “ho cambiato” and “è cambiato.” Or if there is any difference between “ha finito” and “è finito”.
There is. Verbs like cambiare or finire can use both the auxiliaries essere and avere, depending on their function.
And they are not the only ones. In Italian, several verbs use both the auxiliaries essere and avere depending on whether they are used in a transitive or intransitive way.
Transitive and intransitive verbs: what does it mean?
The use of an auxiliary or another in Italian is not random. So, how do you pick up the correct one? It’s easier than you think.
Transitive verbs always use the auxiliary “avere”.
What’s a transitive verb? A transitive verb is a verb followed by an object, which means that the verb has repercussions on the object (something or someone). To make it easier to understand, you know a verb is transtive when it can be naturally followed by the questions “What?” or “Who?”
- Ho cambiato casa – (I changed home) I moved to a different home
- Ho finito il libro – I finished my book
“Cambiare” and “finire” are transitive verbs in this sentence, as they both have repercussions on the object of the sentences (casa and libro)
So, when does the auxiliary “essere” have to be used?
The answer is when the verb of our sentence is intransitive.
What’s an intransitive verb? An intransitive verb performs an action that has no repercussions on the object. Namely, there is not an object in the sentence.
- Il clima è cambiato– the climate has changed
- Il film è finito – the movie is over
As you can see in these sentences, there is no object.
All the Italian verbs with a double auxiliary are those verbs that can be transtive or intrasivite depending on how they are used.
Most Italian verbs are transitive or intransitive. However, there are a number of verbs that can be both: these are the verbs that can have a double auxiliary.
