Cada dia, la professora envia un missatge a la classe.

Because cada means each / every, and in Catalan it is followed by a singular noun.

So:

• cada dia = every day
• not cada dies

This works like:

• cada setmana = every week
• cada any = every year

Even though the meaning is repetitive, the noun stays singular.

La professora is the feminine form of professor / teacher.

In Catalan:

• el professor = the male teacher
• la professora = the female teacher

Depending on context, professor/professora can mean teacher in a school sense, not only professor in the university sense. So in this sentence, la professora is best understood as the teacher.

Catalan normally uses the definite article much more regularly than English before a noun like this.

So Catalan says:

• la professora = the teacher

You generally need the article when talking about a specific person already identified in context. In this sentence, it sounds like a specific teacher, so la professora is the natural form.

Envia is the present indicative, third person singular, of the verb enviar (to send).

So:

• jo envio = I send
• tu envies = you send
• ell/ella envia = he/she sends

Here, la professora envia means the teacher sends.

Because the sentence includes cada dia, the present tense expresses a habitual action:

• Cada dia, la professora envia... = Every day, the teacher sends...

Catalan, like English, often uses the simple present for habitual actions.

Since cada dia means every day, the sentence describes something that happens regularly, not something happening right now at this exact moment.

So:

• envia = sends / does send

If you wanted to emphasize something happening right now, Catalan would usually use a different structure, but here the simple present is the normal choice.

Un missatge means a message.

Catalan uses the indefinite article un / una much like English uses a / an with singular countable nouns.

So:

• un missatge = a message

You would not normally leave it out here, because message is a singular countable noun.

Also:

• missatge is masculine
• so the article is un, not una

A la classe means to the class.

Here it marks the recipient of the message:

• envia un missatge a la classe = sends a message to the class

So the structure is:

• subject: la professora
• verb: envia
• direct object: un missatge
• recipient / indirect object: a la classe

Because classe is a feminine noun.

In Catalan:

• a + el = al
• but a + la = a la (no contraction)

So:

• al professor = to the male teacher
• a la professora = to the female teacher
• a la classe = to the class

Since classe takes la, the correct form is a la classe.

It can mean either, depending on context, but in this sentence it most naturally means the class as a group of students.

So:

• enviar un missatge a la classe = send a message to the class

That sounds like the teacher is sending a message to all the students, not literally to the physical room.

Starting with Cada dia puts the time expression first and gives it a little emphasis.

Catalan often places time expressions at the beginning of the sentence:

• Cada dia, la professora envia un missatge a la classe.

This is very natural and similar to English:

• Every day, the teacher sends a message to the class.

You could also say:

• La professora envia un missatge a la classe cada dia.

That is also correct. The difference is mainly one of focus and style.

The comma is common and helpful, but in short sentences like this it may be optional depending on style.

With an introductory time phrase, Catalan often uses a comma:

• Cada dia, la professora envia un missatge a la classe.

It makes the sentence easier to read, especially when the opening phrase sets the scene.

Yes, Catalan often allows the subject to be omitted because the verb ending already gives information about the subject.

So:

• Cada dia, envia un missatge a la classe.

can mean:

• Every day, she sends a message to the class.

However, including la professora is useful when:

• you want to be explicit about who is doing the action
• you are introducing the subject
• you want extra clarity or emphasis

Missatge can look tricky because the ending -atge is very common in Catalan.

Roughly, missatge sounds like:

• mih-SAHT-juh or mih-SAH-juh, depending on accent and dialect

A few useful notes:

• the stress is on the second syllable: -sat-
• the ending -atge is common in words like viatge (trip/journey)

The spelling may look unfamiliar to an English speaker, but it is a very normal Catalan word formation.

Yes. It follows a very typical pattern:

• Cada dia = time expression
• la professora = subject
• envia = verb
• un missatge = direct object
• a la classe = recipient

So the sentence is completely natural and standard.

Catalan word order is somewhat flexible, but this version is clear, neutral, and very common.
