Para la presentación, ya llevo hechas tres diapositivas, pero todavía no he elegido el título.

Para la presentación means for the presentation. It sets the context right away: the speaker is talking about work being done in preparation for that presentation.

Using para here shows purpose or intended use. In other words, the slides and the title belong to that presentation project.

You could think of it as:

• for the presentation
• as part of the presentation
• for my presentation

Spanish often puts this kind of context at the beginning of the sentence if it helps frame everything that follows.

Here, ya means something like already.

So ya llevo hechas tres diapositivas gives the idea that some progress has already been made:

• I’ve already got three slides done
• I’ve already done three slides so far

It often suggests that the action is further along than zero, or further along than someone might expect.

Compare:

• Llevo hechas tres diapositivas = I have three slides done / I’ve done three slides so far
• Ya llevo hechas tres diapositivas = I’ve already done three slides so far

Both are possible, but they are not exactly the same.

He hecho tres diapositivas simply means:

• I have made three slides

Llevo hechas tres diapositivas focuses more on progress so far:

• I have three slides done so far
• So far, I’ve completed three slides

The pattern llevar + past participle is often used to show how much has been completed up to now. It is very natural when talking about ongoing tasks, projects, books read, exercises finished, and so on.

So in this sentence, llevo hechas tres diapositivas sounds especially suitable because the presentation is still in progress: three slides are done, but the title still hasn’t been chosen.

This structure expresses accumulated progress up to a certain point.

Pattern:

• llevar + participle + noun

Examples:

• Llevo leídos dos capítulos = I’ve read two chapters so far
• Llevamos hechas muchas cosas = We’ve done many things so far
• Lleva escritas diez páginas = She has ten pages written so far

In your sentence:

• llevo = I carry / I have so far
• hechas = done
• tres diapositivas = three slides

So the idea is not just that the action happened, but that this is the amount completed so far.

Because in this structure, the past participle agrees with the noun it refers to.

The noun is tres diapositivas, which is:

• feminine
• plural

So the participle must also be feminine plural:

• hechas

Compare:

• Llevo hecho un esquema = I have one outline done
• Llevo hecha una diapositiva = I have one slide done
• Llevo hechos dos esquemas = I have two outlines done
• Llevo hechas tres diapositivas = I have three slides done

This is different from the normal perfect tense with haber, where the participle does not agree:

• He hecho tres diapositivas — always hecho, never hechas

In this construction, the participle often appears before the noun:

• llevo hechas tres diapositivas
• llevo escritos dos correos
• lleva preparadas varias preguntas

This is the usual pattern with llevar + participle when talking about completed items.

It helps show that hechas belongs closely with the idea of completed, while tres diapositivas tells you what and how many.

Although word order in Spanish can vary, this order is the most natural here.

Yes, absolutely. That sentence is grammatical and natural.

The difference is mainly one of emphasis:

• Ya he hecho tres diapositivas = I have made three slides
• Ya llevo hechas tres diapositivas = I already have three slides done so far

The second version highlights current progress within an unfinished task a bit more strongly.

So:

• he hecho = focuses on the completed action
• llevo hechas = focuses on the amount completed so far

Both work well in context.

Todavía no means still not or haven’t ... yet.

So:

• todavía no he elegido el título = I still haven’t chosen the title / I haven’t chosen the title yet

This is a very common way in Spanish to express that something has not happened up to now.

You can think of it like this:

• ya = already
• todavía no = not yet / still not

That creates a nice contrast in the sentence:

• some progress has already happened
• another part is still unfinished

In this sentence, they mean the same thing:

• todavía no he elegido el título
• aún no he elegido el título

Both mean:

• I haven’t chosen the title yet

Aún no can sound a little more formal or literary in some contexts, but in everyday use both are very common.

For a learner, it is safe to treat them as equivalents in this kind of sentence.

This is an important point, especially for Spanish from Spain.

In Peninsular Spanish, the present perfect (he elegido) is very commonly used for past actions that are connected to the present, especially when talking about:

• today
• this week
• recent events
• current situations with present relevance

Here, the speaker is talking about the current state of the presentation:

• three slides are done
• the title has not been chosen yet

So no he elegido fits very naturally.

In many parts of Latin America, people might more often use the preterite in similar contexts:

• todavía no elegí el título

But in Spain, todavía no he elegido is especially natural.

Spanish often uses the definite article where English might not.

Here, el título means the title, referring to the specific title of that presentation.

Since both speaker and listener can understand which title is meant, Spanish uses the article naturally:

• he elegido el título
• terminé la introducción
• cambié el diseño

English sometimes drops the article in similar situations, but Spanish usually keeps it.

Yes. Elegir is a very natural verb here. It means to choose or to select.

So:

• elegir el título = to choose the title

You could also hear escoger in many contexts, and it often means almost the same thing:

• no he escogido el título

But elegir sounds completely standard and idiomatic in this sentence.

Usually, yes, in modern everyday usage it often means slides in a presentation, such as PowerPoint or Google Slides.

Originally, diapositiva could also refer to a photographic slide, but in a sentence about la presentación, most people will understand it as presentation slides.

So:

• tres diapositivas = three slides

The comma separates the introductory phrase Para la presentación from the main part of the sentence.

It helps the reader hear the structure more clearly:

• Para la presentación, = setting the context
• ya llevo hechas tres diapositivas... = main information

The comma is natural here because the opening phrase is being used as a frame for the whole sentence. Without the comma, the sentence would still be understandable, but the punctuation with the comma is clearer and more standard.
