Siamo lieti del risultato.

Siamo means we are. It is the 1st person plural form of essere (to be).

Present tense of essere:

• io sono = I am
• tu sei = you are
• lui/lei è = he/she is
• noi siamo = we are
• voi siete = you all are
• loro sono = they are

So:

• Siamo lieti = We are pleased
• Sono lieti = They are pleased

English uses are for both we and they, but Italian uses different forms: siamo vs sono.

Lieti is an adjective meaning pleased, glad, or delighted, depending on context.

Its base form is lieto. In the sentence, it becomes lieti because it agrees with noi (we) and is being used for a masculine plural or a mixed-gender group.

Forms:

• lieto = masculine singular
• lieta = feminine singular
• lieti = masculine plural
• liete = feminine plural

Examples:

• Sono lieto. = I am pleased. (male speaker)
• Sono lieta. = I am pleased. (female speaker)
• Siamo lieti. = We are pleased. (all male or mixed group)
• Siamo liete. = We are pleased. (all female group)

Yes, but it sounds a bit more formal, elegant, or polite than some other options.

Common alternatives:

• contento/contenta = happy, pleased
• felice = happy
• soddisfatto/soddisfatta = satisfied

Compare:

• Siamo lieti del risultato. = rather polished/formal
• Siamo contenti del risultato. = more everyday
• Siamo soddisfatti del risultato. = emphasizes satisfaction with the outcome

So lieti is perfectly natural, especially in writing, announcements, professional contexts, or polite speech.

Because Italian commonly uses an article where English often does not.

Del = di + il = of the

So literally:

• Siamo lieti del risultato = We are pleased of the result

But in natural English, that becomes:

• We are pleased with the result or
• We are pleased by the outcome

Italian often uses di after adjectives like lieto, and that di combines with the definite article:

• di + il = del
• di + lo = dello
• di + l' = dell'
• di + la = della
• di + i = dei
• di + gli = degli
• di + le = delle

This is just a difference in how the two languages build the expression.

In Italian, lieto is commonly followed by di:

• essere lieto di qualcosa = to be pleased about something

So:

• lieti del risultato = pleased about / pleased with the result

You should not translate prepositions word for word from English. Italian and English often use different prepositions in the same situation.

Other examples of this kind of mismatch:

• pensare a = to think about
• dipendere da = to depend on
• avere bisogno di = to need

So the safest approach is to learn lieto di as a unit.

You might hear per in some contexts, but del risultato is the more natural and standard choice here.

Difference in feel:

• lieti del risultato = pleased with/about the result itself
• lieti per il risultato = can sound more like pleased because of the result, or pleased on account of it

In this sentence, when talking about satisfaction with an outcome, del risultato is the most idiomatic option.

Adjectives in Italian agree with the people or things they describe.

In Siamo lieti, the adjective describes the implied subject noi (we). If the group is:

• all male, or mixed male/female → lieti
• all female → liete

This is a general rule in Italian adjective agreement.

Examples:

• Marco e Luca sono lieti.
• Anna e Chiara sono liete.
• Marco e Anna sono lieti. (mixed group → masculine plural)

Yes. You just need to change both the verb and the adjective so they agree with the subject.

Examples:

• Sono lieto del risultato. = I am pleased with the result. (male speaker)
• Sono lieta del risultato. = I am pleased with the result. (female speaker)
• È lieto del risultato. = He is pleased with the result.
• È lieta del risultato. = She is pleased with the result.

So the pattern is:

• subject + form of essere
  • matching adjective + di phrase

The normal word order here is:

Siamo lieti del risultato.

That is the most neutral and natural order.

Italian does allow some flexibility, but changing the order usually adds emphasis or sounds more literary. For example:

• Del risultato siamo lieti is possible, but much less neutral and more marked.

For most learners, it is best to keep:

• subject/verb + adjective + complement

A simple pronunciation guide:

• Siamo ≈ SYAH-mo
• lieti ≈ LYEH-tee
• del ≈ del
• risultato ≈ ree-zool-TAH-to

Approximate full pronunciation:

• SYAH-mo LYEH-tee del ree-zool-TAH-to

A few notes:

• si before a vowel here sounds like sya
• ie in lieti is one smooth syllable sequence, not two fully separate English vowels
• the stress in risultato is on -ta-

Yes. This sentence pattern is very useful.

Pattern:

• Siamo lieti di/del/della/dei... + noun

Examples:

• Siamo lieti della decisione. = We are pleased with the decision.
• Siamo lieti dei progressi. = We are pleased with the progress.
• Siamo lieti dell'accordo. = We are pleased with the agreement.
• Siamo lieti della vostra presenza. = We are pleased with your presence.

This is a good model to memorize:

• essere lieto/a/i/e di + something
• with article contraction when needed: del, della, dell', dei, degli, delle
