Invité a un pariente.

Because invité is the first-person singular preterite form of invitar: yo invité = I invited.

The accent mark is important because it distinguishes it from other forms:

• invite = present subjunctive / formal command
• invité = simple past (I invited)

It also shows where the stress goes: in in-vi-TÉ.

It is the preterite tense, which is used for a completed action in the past.

So Invité a un pariente means that the action of inviting happened and is viewed as finished.

Compare:

• Invito a un pariente = I invite / am inviting a relative
• Invitaba a un pariente = I was inviting / used to invite a relative
• Invité a un pariente = I invited a relative

This is the personal a.

In Spanish, when the direct object is a specific person or a person being treated as an individual, you usually put a before it.

So:

• Invité a un pariente = correct
• Invité un pariente = sounds wrong in standard Spanish

Even though un pariente is indefinite (a relative), it still refers to a person, so the personal a is used.

Pariente is a noun of common gender. The word itself stays the same, and the article shows the gender:

• un pariente = a male relative, or sometimes a relative in a general sense
• una pariente = a female relative

So if you know the relative is female, you would usually say:

• Invité a una pariente.

Yes, basically. Pariente means relative or family relation.

However, in everyday Spanish, especially in many contexts, familiar is often more common for family member:

• Invité a un familiar.
• Invité a un pariente.

Both are grammatical, but pariente can sound a bit more formal, more specific to blood/family relation, or simply less common in casual speech depending on context.

Because Spanish often omits subject pronouns when the verb ending already makes the subject clear.

Here, invité clearly means I invited, so yo is not necessary.

You could say:

• Yo invité a un pariente.

But that usually adds emphasis, contrast, or clarity. For example:

• Yo invité a un pariente, no a un amigo.
  I invited a relative, not a friend.

Usually here it means a:

• Invité a un pariente. = I invited a relative.

But un can sometimes mean one, depending on context and emphasis. For example, if you were contrasting numbers, it could be understood as one relative.

Without special context, though, learners should read it as a relative.

A rough pronunciation guide is:

• in-bee-TEH a oon pa-ree-EN-teh

A few useful notes:

• v in Spanish is usually pronounced similarly to a soft b
• the stress in invité is on the last syllable: -té
• pariente is stressed on -rien-: pa-RIEN-te

In IPA (roughly, in standard Spanish):
[im.biˈte a um paˈɾjente]

Yes. This is a very normal Spanish word order:

• Invité = verb
• a un pariente = direct object with personal a

Spanish often allows flexible word order, but this is the most straightforward version.

You could also say:

• A un pariente invité yo.

But that sounds marked or emphatic, not neutral. The original sentence is the natural default.

Not by itself. Invitar means to invite, not to host.

So Invité a un pariente means that you invited a relative.

If you want to say I had a relative over or I hosted a relative, Spanish would usually use other wording depending on the situation, such as:

• Recibí a un pariente en casa.
• Tuve a un pariente en casa.

So it is best to keep invitar = invite.
