Si vols, també podem convidar la meva veïna a la festa.

In Catalan, subject pronouns are often left out because the verb ending already shows who the subject is.

• vols = you want / if you want
• so tu is not necessary

You can say Si tu vols, but it adds emphasis or contrast, as in if you want.

Si vols is an introductory conditional phrase, meaning something like if you want or if you’d like. It sets up the rest of the sentence, so a comma is natural:

• Si vols, també podem...

In English, this works similarly to If you want, we can also...

També means also or too.

So:

• també podem convidar... = we can also invite...

It adds the idea that inviting the neighbor is an additional option.

That is a very normal position in Catalan. Adverbs like també often come before the conjugated verb:

• també podem convidar
• literally: also we-can invite

You may hear podem també convidar in some contexts, but també podem convidar is the most natural choice here.

After poder (can / to be able to), Catalan normally uses a bare infinitive, with no extra preposition:

• podem convidar = we can invite
• puc anar = I can go
• poden venir = they can come

So poder + infinitive works directly.

Catalan usually uses the definite article before a possessive with family members, familiar people, and many everyday nouns:

• la meva veïna = my neighbor
• el meu amic = my friend
• la seva mare = his/her mother

This is different from English, where we do not say the my neighbor.

One important exception: the article is often omitted in direct address and in some fixed expressions.

Because veïna is feminine singular.

The possessive has to agree with the noun:

• el meu veí = my male neighbor
• la meva veïna = my female neighbor

So:

• meu = masculine singular
• meva = feminine singular

The diaeresis on ï shows that the i is pronounced separately, not merged into a diphthong.

So veïna is pronounced roughly as three syllables:

• ve-ï-na

Without the diaeresis, the pronunciation rules would suggest a different sound pattern.

Veïna means female neighbor.

Catalan has masculine and feminine forms here:

• veí = male neighbor
• veïna = female neighbor

If you want to refer to a neighbor without specifying much in English, Catalan still usually chooses one form or the other depending on the person.

Because with convidar, Catalan commonly uses a before the event or place someone is being invited to.

So:

• convidar algú a la festa = to invite someone to the party
• convidar algú a sopar = to invite someone to dinner

Here:

• la meva veïna is the person being invited
• a la festa is the destination/event

Yes. In this sentence:

• podem convidar = we can invite
• la meva veïna = the person invited, so it is the direct object
• a la festa = where/to what event she is invited

So the structure is:

• [subject understood] + podem + convidar + direct object + complement

For the same reason tu is omitted in vols: Catalan usually drops subject pronouns when the verb form already makes the subject clear.

• podem already means we can
• so nosaltres podem is possible, but not necessary

You would add nosaltres mainly for emphasis, contrast, or clarity.

Yes. That would slightly change the tone.

• també podem convidar... = we can also invite...
• també podríem convidar... = we could also invite...

Podríem sounds a bit softer or more tentative, while podem sounds a little more direct and practical. Both can work as suggestions.

Yes, very common. It is often used to make a suggestion sound polite and non-pushy.

Examples:

• Si vols, hi anem demà. = If you want, we can go tomorrow.
• Si vols, t’ajudo. = If you want, I’ll help you.

It is a useful phrase to learn because native speakers use it all the time in conversation.
