Signora, Le preparo una tisana calda subito.

Le is the formal indirect object pronoun meaning to you / for you when speaking politely to one person.

The capital L is a traditional way of showing respect in writing. In modern Italian, many people also write le with a lowercase letter, especially in less formal contexts, but Le is still very common in polite or professional language.

So here:

• Le preparo... = I’ll prepare for you... / I’ll make you...
• formal, polite you

Here Le means for you or to you, not you as the subject.

The verb preparare can take:

• a direct object: the thing being prepared
• an indirect object: the person it is prepared for

So in:

Le preparo una tisana calda subito.

• Le = for you
• preparo = I prepare / I’ll prepare
• una tisana calda = a hot herbal tea
• subito = right away

A very literal breakdown would be:

Madam, for you I prepare a hot herbal tea right away.

More natural English would be:

Madam, I’ll make you a hot herbal tea right away.

In Italian, object pronouns like mi, ti, gli, le, ci, vi usually come before a conjugated verb.

So:

• Le preparo = correct
• preparo Le = not correct in standard Italian here

This is the normal pattern with finite verbs:

• Le parlo. = I’m speaking to you.
• Le porto un bicchiere d’acqua. = I’ll bring you a glass of water.

Pronouns attach to the end of the verb mainly with:

• infinitives: prepararLe
• imperatives: Mi aiuti!
• gerunds: portandoLe

But with preparo, the pronoun goes before it: Le preparo.

Italian often leaves out subject pronouns because the verb ending already shows who the subject is.

Here preparo ends in -o, which tells you the subject is io = I.

So:

• (Io) preparo = I prepare / I’ll prepare

Including io is possible, but it usually adds emphasis:

• Io Le preparo una tisana calda subito.
  = I’ll prepare you a hot herbal tea right away
  with extra emphasis on I

Most of the time, Italian prefers to omit it.

Signora is a polite form of address, like:

• Madam
• Ma’am
• sometimes Mrs. depending on context

Here it is being used to speak directly to the person, so it works like a vocative:

• Signora, Le preparo... = Madam, I’ll prepare...

The comma shows direct address.

A few related forms:

• signora = lady / madam / Mrs.
• Signora Rossi = Mrs. Rossi
• signora in lowercase can also simply mean woman or lady depending on context

Tisana is a feminine singular noun, so it takes the feminine singular indefinite article una.

• una tisana
• not un tisana

This is the normal feminine form before most consonants.

Examples:

• una tisana
• una bevanda
• una camomilla

If the noun began with a vowel, you might see un’ instead:

• un’erba
• un’amica

But tisana begins with t, so it stays una.

Not exactly.

Tisana usually means an herbal infusion or herbal tea, often something soothing or medicinal.

So it is closer to:

• herbal tea
• infusion

rather than ordinary tea made from tea leaves.

Compare:

• tè = tea
• tisana = herbal tea / infusion

So if someone says una tisana calda, they usually mean a hot herbal drink such as chamomile, mint, etc.

Because the adjective must agree with the noun it describes.

Here:

• tisana is feminine singular
• so the adjective must also be feminine singular

That gives:

• tisana calda

Compare:

• tè caldo = hot tea
• tisana calda = hot herbal tea
• bevanda calda = hot drink

So calda matches tisana.

In Italian, adjectives often come after the noun.

So:

• una tisana calda = a hot herbal tea

This is the most neutral and natural order here.

Sometimes adjectives can come before the noun, but that often changes the tone, style, or emphasis. For a basic descriptive adjective like calda, post-noun position is the normal choice.

So:

• una tisana calda = standard, natural

Subito means:

• immediately
• right away
• at once

So the speaker is saying they will do it without delay.

In this sentence:

Signora, Le preparo una tisana calda subito.
= Madam, I’ll prepare you a hot herbal tea right away.

Yes. Italian word order is fairly flexible, especially with adverbs like subito.

These are all possible:

• Le preparo una tisana calda subito.
• Le preparo subito una tisana calda.
• Subito, Le preparo una tisana calda.

The meaning stays very similar, but the emphasis shifts slightly.

• ...calda subito can sound like right away is being added at the end
• preparo subito... puts the immediacy closer to the verb
• Subito... gives very strong emphasis to immediately

Grammatically, preparo is present tense:

• I prepare

But in Italian, the present tense is very often used to talk about the immediate future, especially in everyday speech.

So here it naturally means:

• I’ll prepare
• I’m going to prepare
• I’ll make

This is very common in spoken Italian.

Compare:

• Arrivo subito. = I’ll be right there.
• Le porto un caffè. = I’ll bring you a coffee.
• Preparo io. = I’ll do it / I’ll prepare it.

Yes, but that would change the level of formality.

• Le preparo = formal, polite you
• Ti preparo = informal you

So:

• Signora, Le preparo una tisana calda subito.
  is polite and respectful

Whereas:

• Ti preparo una tisana calda subito.
  would be used with a friend, family member, child, or someone you address informally

Using Signora together with Le makes the sentence sound especially courteous.

Yes, but preparo is very natural here.

It means I prepare or I’ll make, and it works well for food and drinks.

You might also hear:

• Le faccio una tisana calda subito.
• Le preparo una tisana calda subito.

Both can mean I’ll make you a hot herbal tea right away.

However, preparare sounds especially appropriate when talking about getting something ready for someone. It is a very good, natural choice in this sentence.
