Le analisi si fanno al mattino, e l’ambulatorio apre alle sette.

In this sentence, le analisi means the tests or the medical tests. In everyday Italian, analisi often refers to lab tests, especially things like blood tests.

A useful detail: analisi can be singular or plural depending on the article or context.

• l’analisi = the analysis / the test (singular)
• le analisi = the analyses / the tests (plural)

So here, because we have le, it is clearly plural.

Because analisi is one of those Italian nouns whose form stays the same in the singular and plural.

You tell singular vs. plural from the article:

• l’analisi = singular
• le analisi = plural

This is similar to some English nouns that don’t change much in form, though in Italian it can feel surprising at first.

Here si fanno means something like:

• they are done
• people do them
• they’re carried out

So Le analisi si fanno al mattino means Tests are done in the morning.

This is a very common Italian structure called impersonal si or sometimes si passivante, depending on how you analyze it. The important practical point is that it often translates into English as:

• you do...
• people do...
• ...is done / ...are done

No. Even though it looks like a reflexive verb because of si, it is not reflexive here.

• Reflexive: Si lava = He washes himself
• Here: Si fanno = They are done / people do them

So in this sentence, si does not mean themselves. It is part of an impersonal/passive-style construction.

Because le analisi is plural.

With this kind of si construction, the verb often agrees with the thing being talked about:

• L’analisi si fa al mattino = The test is done in the morning
• Le analisi si fanno al mattino = The tests are done in the morning

So:

• singular noun -> fa
• plural noun -> fanno

Both are possible in some contexts, but si fanno is very natural and common in everyday Italian.

Compare:

• Le analisi si fanno al mattino = Tests are done in the morning
• Le analisi sono fatte al mattino = also understandable, but it can sound a bit more formal, literal, or less idiomatic in normal speech

Italian often prefers the si construction for general statements, rules, habits, and procedures.

Al mattino means in the morning.

It is made from:

• a + il = al

And mattino is a masculine singular noun:

• il mattino = the morning
• al mattino = in the morning

Italian often uses a with parts of the day in expressions like this.

Because when telling time, Italian uses a plus the definite article.

• a + le = alle

Why le? Because the understood noun is ore (hours), which is feminine plural:

• le sette (ore) = seven o’clock
• alle sette = at seven

So:

• all’una = at one
• alle due = at two
• alle sette = at seven

Because a combines with different definite articles:

• a + il = al
• a + la = alla
• a + l’ = all’
• a + i = ai
• a + gli = agli
• a + le = alle

So:

• al mattino -> because mattino is masculine singular (il mattino)
• alle sette -> because clock times use feminine plural (le sette ore)

L’ambulatorio usually means a clinic, medical office, or outpatient clinic.

In this sentence, it is the place where the tests are done or where patients go for them.

Depending on context, English translations might include:

• the clinic
• the outpatient clinic
• the medical office
• sometimes the lab, if that is the practical meaning in context

But the most direct general translation is clinic.

Because it is short for lo ambulatorio or, more practically in modern Italian usage, l’ambulatorio before a vowel.

In Italian, the singular definite articles il or lo often become l’ before a vowel:

• l’analisi
• l’ambulatorio
• l’ospedale

So the apostrophe shows that the article has been shortened.

Because apre means opens, while è aperto means is open.

So there is a difference:

• L’ambulatorio apre alle sette = The clinic opens at seven
• L’ambulatorio è aperto dalle sette = The clinic is open from seven

The sentence is talking about the opening time, so apre is the right choice.

Because in Italian, the present tense is often used for:

• habits
• general truths
• schedules
• regular procedures

So:

• Le analisi si fanno al mattino = a general rule/habit
• L’ambulatorio apre alle sette = a regular schedule

English does something similar:

• The clinic opens at seven
• Tests are done in the morning

Yes, often you can.

• al mattino = in the morning
• di mattina = in the morning / in the mornings

Both are common, though there can be slight differences in tone or emphasis depending on context.

Here, al mattino sounds very natural for a general routine or institutional schedule.

Not automatically, but very often that is what people mean in medical contexts.

By itself, analisi can refer to different kinds of tests or analyses. In everyday healthcare situations, though, many people will understand le analisi as lab tests, especially blood tests, unless the context says otherwise.

The sentence uses very normal Italian word order.

• Le analisi si fanno al mattino
• l’ambulatorio apre alle sette

This is straightforward and neutral.

You could rearrange parts for emphasis, but the given version is the most natural basic phrasing for a learner to know.

Because Italian usually does not need subject pronouns unless they are needed for emphasis or clarity.

Also, in the first clause there is no personal subject like we or they at all, because si fanno is impersonal/passive in meaning.

In the second clause, the subject is already stated:

• l’ambulatorio apre

So adding pronouns would usually be unnecessary.
