La mudança és demà.

Here mudança means move, especially a house move or the act of moving.

So La mudança és demà means The move is tomorrow.

It is a real Catalan word, but depending on the region and context, learners may also hear expressions like trasllat or mudança de casa. In everyday speech, the most natural choice can vary by dialect, but mudança is understandable.

Because mudança is a feminine singular noun in Catalan, so it takes the feminine singular article la.

• la mudança = the move
• una mudança = a move

This is similar to many Catalan nouns ending in -a, which are often feminine.

És is the third-person singular present tense of ser, which means to be.

So in this sentence:

• la mudança = the subject
• és = is
• demà = tomorrow

It matches the singular subject la mudança, so és means is.

Catalan usually uses ser for dates, times, and scheduled events.

So when you say that an event happens tomorrow, ser is the normal choice:

• La reunió és demà = The meeting is tomorrow
• L’examen és dilluns = The exam is on Monday

Estar is normally used for location or temporary states, not for saying when an event takes place.

Demà means tomorrow.

Just like in English, you normally do not need a preposition before it in this kind of sentence.

• La mudança és demà = The move is tomorrow

You do not need something equivalent to on tomorrow. Catalan, like English, usually says simply demà.

Yes, you could, but the nuance is slightly different.

• La mudança és demà is the most natural way to say a scheduled near-future event.
• La mudança serà demà also means The move will be tomorrow, but it can sound a bit more explicitly future-oriented or formal.

Catalan often uses the present tense for planned future events, just like English does in sentences like The move is tomorrow.

Yes, but the emphasis changes.

• La mudança és demà is the neutral, standard order.
• Demà és la mudança is possible, but it puts more focus on demà.

So if you are just stating the fact normally, La mudança és demà is the best choice.

A simple learner-friendly pronunciation is:

moo-DAN-sa

A few useful details:

• The stress is on dan
• The ç is pronounced like s
• So ça sounds like sa

That means mudança is roughly moo-DAN-sa, not moo-DAN-ka

The accent marks help with stress and sometimes distinguish words.

• és has an accent to mark the verb form is, and to distinguish it from es, which can be a pronoun.
• demà has an accent to show that the stress falls on the last syllable: de-MA

So the accents are important both for pronunciation and for identifying the correct word.

Yes, it is grammatical and understandable.

It is a short, natural type of sentence for talking about a scheduled event. A Catalan speaker might also choose slightly different vocabulary depending on region and context, but structurally the sentence is perfectly normal:

• La mudança és demà = The move is tomorrow

It is a good example of how Catalan uses ser plus a time expression for events.
