El presentador lee el cuestionario.

Because the sentence has two different nouns:

• el presentador = the presenter / host
• el cuestionario = the questionnaire

In Spanish, articles are usually used more often than in English, and each noun normally keeps its own article. So Spanish says the presenter reads the questionnaire, with the before both nouns.

Also, both nouns are masculine singular, so the article is el in both cases.

Leer is the infinitive, meaning to read.
In the sentence, the verb is conjugated to match el presentador, which is he / she / it form, third person singular.

Present tense of leer:

• yo leo
• tú lees
• él / ella / usted lee
• nosotros / nosotras leemos
• vosotros / vosotras leéis
• ellos / ellas / ustedes leen

So El presentador lee means The presenter reads or is reading, depending on context.

In the present tense, leer behaves mostly like a regular -er verb, but because the stem ends in a vowel, some forms may look a little unusual at first.

For example:

• leo
• lees
• lee

The endings are still the normal present-tense endings for an -er verb, but the double e in forms like lee comes from combining the stem le- with the ending.

So for this sentence, it is best to think of lee as the normal third-person singular present form of leer.

In standard Spain Spanish, lee is pronounced roughly as LEH-eh, with two vowel sounds:

• le-e

It is not like English lee in Bruce Lee.
It comes from leer, which is pronounced le-er.

So the full sentence would sound approximately like:

• el pre-sen-ta-DOR LEH-eh el kwes-tyo-NA-ryo

That said, in fast speech, the two e sounds may run together a bit, but learners should think of lee as having two vowel beats.

Spanish often leaves out subject pronouns when they are not needed. The verb ending already tells you who the subject is, and here the noun phrase el presentador clearly states it anyway.

So Spanish says:

• El presentador lee

not usually:

• El presentador él lee

Adding él would sound unnecessary or emphatic in most normal contexts.

This is a very common question.

• el = the → article
• él = he / him → pronoun

In your sentence, both instances are el without an accent because they are articles:

• El presentador
• el cuestionario

If you wrote Él presentador, that would be wrong.

Yes, cuestionario is masculine singular, so it takes el.

A useful general pattern is:

• nouns ending in -o are often masculine
• nouns ending in -a are often feminine

So:

• el cuestionario
• plural: los cuestionarios

Like many rules in Spanish, this is a pattern, not an absolute law, but here it works exactly as expected.

It can mean either one, depending on context.

Spanish present tense often covers both:

• reads = habitual action
• is reading = action happening now

So El presentador lee el cuestionario could mean:

• The presenter reads the questionnaire
• The presenter is reading the questionnaire

If Spanish wants to make the ongoing action extra clear, it can also use:

• El presentador está leyendo el cuestionario

But the simple present is still very common.

This word order is the most neutral and standard:

• subject + verb + object

So:

• El presentador = subject
• lee = verb
• el cuestionario = direct object

Spanish does allow some word-order flexibility, but changing the order usually adds emphasis, sounds literary, or depends on context. For a learner, the standard order here is the safest and most natural choice.

Presentador is a noun meaning something like presenter, host, announcer, or TV/radio presenter, depending on context.

It comes from the verb presentar = to present / introduce.

It also has a feminine form:

• el presentador
• la presentadora

So if the speaker were female, the sentence could become:

• La presentadora lee el cuestionario

El cuestionario is the direct object. It tells you what is being read.

You can find the direct object by asking:

• What does the presenter read?

Answer:

• el cuestionario

So the structure is:

• El presentador = who does the action
• lee = the action
• el cuestionario = what receives the action

Because it is a thing, not a person.

In Spanish, the personal a is used before a specific human direct object, and sometimes pets or personified beings. But el cuestionario is an object, so no a is used.

That is why you say:

• El presentador lee el cuestionario

not:

• El presentador lee a el cuestionario

You would make the nouns and verb plural as needed.

For example:

• Los presentadores leen el cuestionario = The presenters read the questionnaire
• El presentador lee los cuestionarios = The presenter reads the questionnaires
• Los presentadores leen los cuestionarios = The presenters read the questionnaires

Notice the changes:

• el → los
• presentador → presentadores
• lee → leen
• cuestionario → cuestionarios
