L'actor ja té el programa; si vols, demà te'l ensenyarà abans de seure.

Because Catalan normally contracts the singular article el to l' before a word beginning with a vowel or silent h.

• el + actor → l'actor
• el + home → l'home

So L'actor simply means the actor.

Here ja means already:

• ja té el programa = already has the program

In other contexts, ja can also have meanings like now, well, or add emphasis, but in this sentence already is the natural interpretation.

Té is the he/she/it has form of tenir (to have).

The accent helps show both pronunciation and meaning. It also distinguishes té from other forms spelled te, such as:

• te = tea
• te as part of a pronoun combination, as in te'l

So:

• té = has
• te ≠ has

Catalan usually leaves out subject pronouns unless they are needed for emphasis, contrast, or clarity.

So:

• si vols = if you want
• si tu vols = also possible, but more emphatic, like if you want

The verb ending -s already shows that the subject is you (informal singular), so tu is not necessary.

It is literally if you want, but very often it works like English if you like or if you want as a soft, friendly suggestion.

So in this sentence, si vols sounds natural and idiomatic, not overly literal.

Te'l is a combination of two weak pronouns:

• te = to you
• 'l = it / him (here it, referring to el programa)

So:

• te'l ensenyarà = he will show it to you

Because programa is masculine singular, the direct-object pronoun is el, which becomes 'l in this combination.

Catalan weak pronouns often change shape when they combine.

By itself, the unstressed form for you is usually et before a verb:

• et veig = I see you

But when it combines with another pronoun like el, the form becomes te:

• te + el → te'l

This is just the standard combined clitic form. It is something learners usually need to memorize as a pattern.

Because in Catalan, unstressed object pronouns normally go before a conjugated verb.

So:

• te'l ensenyarà = correct

This is very normal with finite verb forms. Compare:

• before a conjugated verb: te'l ensenyarà
• attached to an infinitive: ensenyar-te'l
• attached to an affirmative command: ensenya-te'l

So the position depends on the verb form.

Ensenyarà is the simple future, 3rd person singular, from ensenyar (to show, to teach depending on context).

Here it means:

• he/she will show

Since the subject is l'actor, the meaning is:

• the actor will show it to you

Demà means tomorrow.

It tells you when the action will happen:

• si vols, demà te'l ensenyarà = if you want, tomorrow he will show it to you

Catalan word order is fairly flexible with time expressions like demà. You could also say:

• si vols, te'l ensenyarà demà

Both are possible. In your sentence, putting demà earlier gives it a bit more prominence.

Catalan often uses abans de + infinitive where English uses before + -ing or before + subject + verb.

So:

• abans de seure = before sitting down / before he sits down

Using the infinitive is especially natural when the subject is the same as in the main clause, or when the subject is understood from context.

Here seure is best understood as to sit down or to take a seat.

In context:

• abans de seure = before sitting down

Catalan often uses seure where English would naturally say sit down. It does not need a reflexive pronoun here.

Normally, the understood subject of seure is the same as the subject of the main verb, so the default reading is:

• the actor will show it to you before he sits down

If the speaker meant before you sit down, Catalan would usually make that clearer in some other way.
