La terapia dura cinque giorni e c’è anche un antibiotico leggero.

In Italian, nouns are often used with an article where English might leave it out. So la terapia is the normal way to say the therapy / the treatment.

Using no article, terapia, is possible in some contexts, but in a sentence like this, la terapia sounds much more natural and complete.

Dura comes from the verb durare, which means to last.

So:

• la terapia dura = the treatment lasts
• dura cinque giorni = it lasts five days

It is third-person singular present, because the subject is la terapia, which is singular.

Italian often expresses duration directly, without needing a preposition.

So:

• dura cinque giorni = it lasts five days

This is perfectly normal Italian. English usually needs for in some structures, but Italian often does not.

Yes, you can say dura per cinque giorni, and it also means it lasts for five days.

However, dura cinque giorni is usually more direct and very common. Adding per is not wrong, but it can sound a little more explicit or slightly heavier depending on context.

C’è means there is.

It is made from:

• ci = a little word used in expressions like there
• è = is

Together:

• c’è = there is

So:

• c’è anche un antibiotico leggero = there is also a mild antibiotic

Because it combines two elements:

• ci
• è

When ci comes before è, it becomes c’è.

The apostrophe shows that part of ci has disappeared.
The accent on è is important because it shows this is the verb is, not the conjunction e meaning and.

So:

• e = and
• è = is

In this sentence, anche means also / too.

Italian often places anche close to the word or idea it is adding. Here:

• c’è anche un antibiotico leggero

means there is also a mild antibiotic.

That word order is very natural. It sounds like the speaker is adding extra information: not only is there the treatment, but there is also an antibiotic.

Because antibiotico is a masculine singular noun, and the correct indefinite article here is un.

For masculine singular nouns:

• un is used before most consonants and vowels
• uno is used before certain special sounds, such as z, s + consonant, ps, gn

Examples:

• un antibiotico
• un amico
• uno studente
• uno zaino

So antibiotico takes un, not uno.

Because adjectives in Italian usually agree with the noun they describe.

Here, leggero describes antibiotico, which is:

• masculine
• singular

So the adjective must also be masculine singular:

• un antibiotico leggero

If the noun were feminine singular, you would use leggera.

Yes, leggero literally means light, but in many contexts it means mild, gentle, or not too strong.

So un antibiotico leggero usually means:

• a mild antibiotic
• an antibiotic that is not very strong

This is a very common extension of the meaning of light in both Italian and English.

Yes. Terapia is often translated as therapy, but depending on context it can also mean treatment.

In a medical sentence like this, English may often prefer treatment rather than therapy, even though the Italian word is still terapia.

So the best translation depends on context, not just on the dictionary meaning of the word.

Because Italian normally does not need subject pronouns when the verb form already makes the subject clear.

Here, the subject is explicitly stated:

• La terapia dura cinque giorni

So there is no need to add a separate word for it. Italian is a pro-drop language, which means subject pronouns are often omitted when they are unnecessary.

Giorni is pronounced approximately like JOR-nee.

A few useful points:

• gi before o sounds like the j in job
• or sounds like or
• ni here is like nee

So:

• giorni ≈ JOR-nee

The gn sound in Italian can sometimes be tricky in words like lasagna, but in giorni it is usually easiest for English speakers to think of the word as roughly JOR-nee.
