La rifa incluye un sorteo.

They are related, but not identical.

• rifa = a raffle: the whole activity or fundraiser where people buy numbered tickets for a prize
• sorteo = the draw: the moment or procedure where the winning number/name is chosen at random

So La rifa incluye un sorteo means the raffle includes a draw. In real life, a rifa normally does involve a sorteo, so a learner might feel the sentence is a bit obvious or repetitive. But grammatically it is fine, and it highlights the difference between the event and the drawing itself.

Because Spanish nouns have grammatical gender.

• rifa is feminine, so it takes la
• sorteo is masculine, so it takes un

That gives:

• la rifa
• un sorteo

This gender is a property of the noun itself, not of the thing in real life.

Incluir is the infinitive, meaning to include.

In the sentence, the verb is conjugated to match the subject la rifa:

• incluir = to include
• la rifa incluye = the raffle includes

Here, incluye is:

• present tense
• third person singular
• used because la rifa = it

So the structure is:

• La rifa = subject
• incluye = verb
• un sorteo = object

In standard Spain Spanish, it is roughly:

• in-CLU-ye

IPA: /iŋˈklu.ʝe/ or /iŋˈklu.je/ depending on accent and pronunciation style.

A useful approximation for an English speaker is:

• een-KLOO-yeh

Notes:

• The stress is on clu
• The y sound in -uye is not like English why; it is softer
• The final e is pronounced, not silent

A simple pronunciation guide:

• rifa → REE-fa
• sorteo → sor-TE-o

IPA:

• rifa: /ˈri.fa/
• sorteo: /soɾˈte.o/

Important point for sorteo:

• it has three syllables: sor-te-o
• the e and o are pronounced separately

In Spain, the r in rifa and sorteo is a tapped Spanish r, not the English r.

In normal Spanish, you would usually keep the articles:

• La rifa incluye un sorteo

Why?

• la refers to a specific raffle
• un introduces a draw, one draw, as a countable thing

Rifa incluye sorteo sounds incomplete or unnatural as a full standard sentence.

That said, in advertising or very compressed promotional language, Spanish sometimes drops articles more than English would, for example in headings or bullet points. But as a normal sentence, La rifa incluye un sorteo is the correct form.

Yes, incluye is correct, but other verbs are possible depending on nuance.

Examples:

• La rifa incluye un sorteo.
  The raffle includes a draw.

• La rifa consiste en un sorteo.
  The raffle consists of a draw.

• La rifa se decide por sorteo.
  The raffle is decided by a draw.

The difference is subtle:

• incluye suggests the draw is one part of the raffle
• consiste en suggests the draw is the essential mechanism of the raffle

The normal, neutral order is:

• La rifa incluye un sorteo.

That is the standard Spanish pattern:

• subject + verb + object

You could change the order for emphasis, but it would sound less neutral. For example:

• Un sorteo lo incluye la rifa. — grammatical, but unusual and marked
• Incluye un sorteo la rifa. — possible in very specific contexts, but not the normal choice

So for learners, the original word order is the one to use.

Usually, yes, that is the closest translation.

In Spain, rifa commonly refers to:

• selling tickets or numbers
• assigning a prize
• choosing the winner randomly

Depending on context, English might also say raffle, prize draw, or sometimes lottery, but raffle is usually the best match.

Just be careful with lottery:

• lotería often refers to a more formal or official lottery system
• rifa is often smaller-scale, local, informal, or charitable

Yes. In Spanish, nouns ending in -o are very often masculine, and sorteo follows that common pattern:

• el sorteo
• un sorteo

Likewise, nouns ending in -a are often feminine, and rifa follows that pattern:

• la rifa

These are not absolute rules, but they are very common and helpful for learners.

Yes, if the meaning changes.

• La rifa incluye un sorteo. = the raffle includes one draw
• La rifa incluye sorteos. = the raffle includes draws / multiple drawings

If you say incluye sorteos without unos, it sounds more general and is often natural in Spanish.

So the singular or plural depends entirely on how many draws are involved.

It is grammatically natural, but semantically it can sound a little redundant because a rifa normally works through a sorteo.

A native speaker might more often say things like:

• La rifa se celebrará por sorteo.
• La rifa tendrá lugar mediante un sorteo.
• La rifa incluye varios premios y un sorteo final.

So the original sentence is fine for learning grammar and vocabulary, but in real-life usage, speakers might choose wording that adds more specific information.
