Potser demà canviarem l'hora de la classe.

Potser means maybe, perhaps, or possibly. It is very common in everyday Catalan.

In this sentence, Potser demà canviarem l'hora de la classe means something like Maybe tomorrow we’ll change the time of the class.

You can think of potser as an adverb that comments on the whole sentence.

Putting potser at the beginning is very natural because it sets the tone right away: the speaker is saying that the whole statement is uncertain.

Catalan word order is fairly flexible, so you could also hear:

• Demà potser canviarem l'hora de la classe
• Potser canviarem l'hora de la classe demà

All of these are possible, but the original version sounds very natural.

Demà means tomorrow.

The accent mark on à shows where the stress falls: de-MÀ.
Without getting too technical, the written accent helps mark the correct pronunciation and stress.

So:

• demà = tomorrow

Canviarem is the future simple of canviar (to change), in the first person plural:

• jo canviaré = I will change
• tu canviaràs = you will change
• ell/ella canviarà = he/she will change
• nosaltres canviarem = we will change
• vosaltres canviareu = you all will change
• ells/elles canviaran = they will change

So canviarem means we will change.

Because in Catalan, it is completely normal to use the future tense even when a time word like demà already makes the timing clear.

So demà canviarem is a standard, natural way to say tomorrow we will change.

In some languages, speakers often use the present tense for future events, but here the future tense fits very naturally.

The infinitive is canviar, which means to change.

So:

• canviar = to change
• canviarem = we will change

This is a regular -ar verb.

Because hora is a feminine noun that normally takes la, but when la comes before a word beginning with a vowel or a silent h, it contracts to l'.

So:

• la hora → l'hora

This is the same kind of thing you see in:

• l'aigua = the water
• l'escola = the school
• l'hotel = the hotel

Even though you see l', the noun is still feminine:

• l'hora = the hour / the time

Yes. Hora is a feminine noun.

That is why the full article would be la:

• la hora → l'hora

You can also see its gender in other phrases, such as:

• una hora = one hour
• bona hora = good time / appropriate time

Here, hora means time in the sense of a scheduled time.

So l'hora de la classe means:

• the time of the class
• more naturally in English: the class time or the time of the lesson

It does not mean hour in the literal counting sense here, even though hora can also mean hour in other contexts.

De la classe literally means of the class.

So:

• l'hora de la classe = the time of the class

This is a very common Catalan structure: noun + de + noun.

Examples:

• el final de la pel·lícula = the end of the film
• la porta de la casa = the door of the house
• l'inici de la reunió = the start of the meeting

It can mean either, depending on context.

In this sentence, la classe most likely means the lesson or the class session, because the sentence talks about changing its time.

So l'hora de la classe is most naturally understood as:

• the time of the class
• the class time

Because demà is used on its own, just like tomorrow in English.

You do not need an article:

• demà = tomorrow

So:

• Potser demà... = Maybe tomorrow...

Yes. Catalan allows some flexibility in word order, especially with adverbs like potser and time expressions like demà.

Possible alternatives include:

• Demà potser canviarem l'hora de la classe
• Potser canviarem l'hora de la classe demà
• Canviarem l'hora de la classe demà, potser (less neutral, more marked)

The original sentence is a very natural, neutral choice.

The h in hora is silent, so l'hora is pronounced as if the two parts flow together.

A rough guide:

• l'hora ≈ LOR-uh / LO-ra, depending on accent

The important point is that the h is not pronounced.

Catalan often uses de where English might prefer a compound noun.

So English:

• the class time

often becomes Catalan:

• l'hora de la classe
• literally, the time of the class

This is a very normal difference between the two languages.

Yes. Potser can correspond to both maybe and perhaps.

• maybe is a very natural everyday translation
• perhaps is also correct, but sounds a bit more formal in English

So depending on tone, the sentence could be:

• Maybe tomorrow we’ll change the time of the class
• Perhaps tomorrow we’ll change the class time

Both are fine.

Yes. It is fully grammatical and sounds natural.

It has:

• an adverb of uncertainty: potser
• a time expression: demà
• a future verb: canviarem
• a direct object: l'hora de la classe

So it is a perfectly normal everyday Catalan sentence.
