Bevo una tisana calda prima di dormire.

In Italian, the subject pronoun is often omitted because the verb ending already shows who is doing the action.

• bevo = I drink
• the -o ending tells you it is io

You can say io bevo, but it is usually only added for emphasis, contrast, or clarity.

• Bevo una tisana calda = normal, neutral
• Io bevo una tisana calda, lui invece prende il caffè = I drink a hot herbal tea, while he has coffee

Bevo is the present indicative of bere.

In a sentence like this, the Italian present tense is often used for:

• habits
• routines
• things you usually do

So it can describe something like a regular habit, not only something happening right now.

Tisana is a singular countable noun, so Italian normally needs an article here.

• una tisana = a herbal tea / an herbal infusion

Unlike English, Italian often cannot leave out the article with a singular noun of this kind. So bevo una tisana calda sounds natural, while bevo tisana calda would sound incomplete or unnatural in most normal contexts.

Because calda has to agree with tisana.

• tisana is feminine singular
• so the adjective must also be feminine singular
• caldo = masculine singular
• calda = feminine singular

So:

• un tè caldo
• una tisana calda

In Italian, many descriptive adjectives commonly come after the noun.

So:

• una tisana calda is the normal order

You may sometimes see adjectives before the noun, but that often changes the tone, emphasis, or style. For a basic descriptive meaning, putting calda after tisana is the most natural choice.

Yes, it is possible, but it sounds more marked, literary, or expressive.

• una tisana calda = the normal, everyday way
• una calda tisana = more stylistic, sometimes more evocative

For most learners, una tisana calda is the safer and more natural choice in ordinary speech.

Because Italian uses prima di + infinitive when the subject is the same.

Here, the same person both:

• drinks the herbal tea
• sleeps

So Italian says:

• prima di dormire = before sleeping / before going to sleep

This is a very common pattern:

• prima di uscire
• prima di mangiare
• prima di studiare

If the subject changes, Italian usually uses a different structure, such as prima che + a verb in the subjunctive.

After prima di, Italian normally uses the infinitive when the action has the same subject as the main verb.

So:

• Bevo ... prima di dormire means that I drink and I sleep

The infinitive is the standard structure here. English often uses before sleeping or before I sleep, but Italian strongly prefers prima di + infinitive in this kind of sentence.

Yes. That is also very natural.

• prima di dormire = shorter, simpler
• prima di andare a dormire = more explicitly before going to bed / before going to sleep

Both are correct. The longer version just spells out the idea a bit more.

Not exactly.

• tè usually means actual tea made from tea leaves
• tisana usually means an herbal infusion, often caffeine-free

So in Italian, tisana is a specific word and is very commonly used for chamomile, herbal blends, digestive infusions, and similar drinks.

Italian often expresses this idea without mentioning the container.

So:

• Bevo una tisana is perfectly natural

If you want to be more specific, you could say:

• Bevo una tazza di tisana
• Bevo una tisanа

Both can work, but the shorter version is very common when the focus is on the drink itself rather than the exact quantity.

It can definitely describe a habit.

The Italian present tense often covers both:

• what someone is doing now
• what someone usually does

So Bevo una tisana calda prima di dormire can easily mean a routine or nightly habit, depending on context.

The given order is the most natural neutral order:

• Bevo una tisana calda prima di dormire.

But Italian can move elements for emphasis.

For example:

• Prima di dormire, bevo una tisana calda.

That still sounds natural. The meaning stays the same, but the sentence now highlights the time expression first.
