A remessa não chegou; daí o extravio.

Remessa means something like shipment, consignment, or dispatch. It is a bit more formal and administrative than encomenda.

• encomenda = a package/order/parcels in everyday language
• remessa = a shipment, often used in logistics, transport, business, or official contexts

So in this sentence, a remessa sounds more formal than if you said a encomenda.

Because the subject is a remessa, which is third person singular, so the verb must also be in the third person singular:

• a remessa chegou = the shipment arrived
• a remessa não chegou = the shipment did not arrive

This is the pretérito perfeito (simple past), used here to refer to a completed event in the past.

Here daí means something like:

• hence
• therefore
• that is why
• from that

So A remessa não chegou; daí o extravio means that the shipment’s not arriving is what leads to the conclusion of loss/misplacement.

Important: this is a more compact, slightly formal use of daí. In other contexts, daí can also literally mean from there.

The semicolon links two closely connected parts:

• A remessa não chegou
• daí o extravio

It shows that the second part is a consequence of the first. A full stop would separate them more strongly; a comma would often feel weaker or less careful in this kind of formal written sentence.

So the semicolon helps convey: first fact -> resulting conclusion.

Extravio means loss, misplacement, or disappearance, especially in a postal, delivery, luggage, or administrative context.

It is more specific and formal than a general word like perda.

For example:

• extravio de bagagem = lost luggage
• extravio de documentos = misplacement/loss of documents

In this sentence, o extravio means the shipment was apparently lost or went missing.

Portuguese often uses the definite article where English might not.

So:

• o extravio = the loss / the misplacement

Here the article makes the noun sound like a specific, identifiable event: the loss in question, i.e. the loss of that shipment.

Without the article, the sentence would sound less natural in this structure.

Yes. The second part, daí o extravio, is an elliptical structure: some words are left out because the meaning is clear.

You can think of it as a shortened version of something like:

• daí concluir-se o extravio
• daí resultar o extravio
• daí ter havido extravio

Portuguese, especially in formal or written style, often allows this kind of compact phrasing.

It is understandable and correct, but it sounds formal, concise, and a bit administrative or written.

In more everyday speech, a speaker might say something like:

• A remessa não chegou, por isso deve ter-se extraviado.
• A encomenda não chegou, portanto perdeu-se.
• A encomenda não chegou; deve ter havido extravio.

So the original sentence is natural, but not especially conversational.

Yes. Depending on tone and style, you could use:

• por isso = therefore / that’s why
• portanto = therefore
• daí que = hence / which is why
• logo = therefore

For example:

• A remessa não chegou; por isso, houve extravio.
• A remessa não chegou; portanto, houve extravio.

But daí o extravio is especially compact and elegant in a formal register.

It can, but daí is shorter and more idiomatic in this kind of concise written statement.

Compare:

• por causa disso = because of that
• daí = hence / from that / therefore

Both can express a consequence, but daí is often preferred when the writer wants a tighter, more economical style.

In European Portuguese, daí is pronounced roughly like da-EE, with the stress on the second syllable because of the accent:

• da-Í

The accent mark tells you the final í is stressed.

So the rhythm is:

• A remessa não chegou; da-Í o extravio.
