Ogni membro riceve una carta.

Because ogni is followed by a singular noun in Italian.

• ogni membro = each member / every member
• not ogni membri

This is different from English, where every also takes a singular noun: every member.

So even though the idea refers to multiple people overall, Italian expresses it with:

• ogni + singular noun

After ogni, Italian normally does not use an article.

So you say:

• ogni membro
• ogni giorno
• ogni persona

Not:

• ogni il membro

Ogni already works like a determiner, so no article is needed.

It can mean either each or every, depending on context.

In this sentence, ogni membro riceve una carta could be understood as:

• Each member receives a card
• Every member receives a card

In many cases, Italian ogni covers both ideas.

A small nuance:

• each can sound a little more individual
• every can sound a little more general

But in a simple sentence like this, ogni works well for both.

Riceve is the third person singular present tense of ricevere (to receive).

Conjugation:

• io ricevo = I receive
• tu ricevi = you receive
• lui/lei riceve = he/she receives

Here the subject is ogni membro, which is grammatically singular, so the verb must also be singular:

• Ogni membro riceve ...

Because the grammatical subject is ogni membro, and that expression is treated as singular in Italian.

So Italian sees it as:

• each member → singular
• therefore receives → singular

This is the same logic as in English:

• Every member receives a card
• not Every member receive a card

Italian often does not use subject pronouns unless they are needed for emphasis or clarity.

So instead of saying:

• Ogni membro lui/lei riceve una carta

Italian simply says:

• Ogni membro riceve una carta

The subject is already clear from ogni membro, so no extra pronoun is necessary.

Because carta is a feminine singular noun.

The indefinite articles are:

• un for many masculine singular nouns
• una for feminine singular nouns

So:

• un membro
• una carta

That is why the sentence uses una carta.

Carta can have several meanings depending on context, such as:

• card
• paper
• sheet of paper
• sometimes other related meanings

In this sentence, if the meaning has been given as card, then una carta means a card.

Context is important, because carta is a flexible word in Italian.

Yes, Italian word order is somewhat flexible, but the normal and most neutral order here is:

• Ogni membro riceve una carta.

You may sometimes see changes for emphasis, but this standard order is best for learners:

• subject → verb → object

So this sentence is a very natural basic structure.

Yes, that is also correct, but it is not exactly the same structure.

• Ogni membro riceve una carta = Each/Every member receives a card
• Tutti i membri ricevono una carta = All the members receive a card

Differences:

• ogni + singular noun
• tutti i + plural noun

Both can express a similar idea, but ogni membro focuses on the members one by one, while tutti i membri presents them as a group.

Yes. Membro is grammatically masculine as a noun.

So you say:

• un membro
• ogni membro

This grammatical gender does not necessarily tell you the real-life gender of the person. It can refer to a member regardless of whether that person is male or female, depending on context.

Italian often uses the present tense for general statements, routines, instructions, and facts.

So Ogni membro riceve una carta can mean something like:

• this is what normally happens
• this is the rule
• this is the procedure

It does not have to mean only what is happening right now at this exact moment.
