Basic linkers (perché, quindi, ma, però)

Resto a casa perché piove.I'm staying at home because it's raining.

A linker joins two short ideas and shows how they relate. Four small words do most of the work in everyday Italian: perché gives a reason, quindi gives a result, and ma and però show a contrast.

Quick shortcut: perché = the reason (because), quindi = the result (so), ma / però = the contrast (but). With the same two facts, you choose the linker that matches how you see the link between them.

1. Perché: the reason (and the question)

Perché has two jobs. As a question word it means why; as a linker it means because:

• Perché studi italiano? (Why are you studying Italian?)
• Studio italiano perché lavoro in Italia. (I'm studying Italian because I work in Italy.)
• Perché non vieni? — Perché sono stanco. (Why aren't you coming? — Because I'm tired.)

The reason comes after perché, and a short answer can start with it. In writing, perché has an acute accent on the last letter (é). For other question words, see Question words.

2. Quindi: the result

Quindi introduces what follows from the first idea. It means so or therefore:

• Piove, quindi resto a casa. (It's raining, so I'm staying at home.)
• Ho fame, quindi mangio un panino. (I'm hungry, so I'm eating a sandwich.)
• Domani è domenica, quindi non lavoro. (Tomorrow is Sunday, so I'm not working.)

The first idea comes first, and quindi starts the second one. A comma before quindi is common.

3. Ma and però: the contrast

Ma and però both mean but. They add an idea that goes against what you might expect after the first one:

• Mi piace il vestito, ma è troppo caro. (I like the dress, but it's too expensive.)
• Mi piace il vestito, però è troppo caro. (I like the dress, but it's too expensive.)
• Il film è lungo, ma è bello. (The film is long, but it's good.)

In many sentences you can use either one. Ma is the everyday default and always stands at the start of its clause. Però is a little more flexible: it can start the clause, or it can follow the first word or phrase, as in Marco però non viene. (Marco, though, isn't coming.)

4. One situation, three linkers

The same facts can be linked in different ways, depending on what you want to say:

With perché, the reason follows the linker. With quindi, the result follows it. Switching them changes the meaning: Resto a casa perché piove and Piove perché resto a casa are not the same idea.

Using several linkers in one sentence can sound heavy, so it often helps to split a long sentence in two. For more formal options, see Linkers of cause and consequence and Linkers of contrast.

Common mistakes

• ❌ Perchè sei in ritardo? → ✅ Perché sei in ritardo? (the accent is acute: é)
• ❌ Per che sei in ritardo? → ✅ Perché sei in ritardo? (perché is one word)
• Reason and result are easy to swap by accident. Piove, perché resto a casa is grammatical, but it says that staying home makes it rain; for the intended meaning you can write Piove, quindi resto a casa or Resto a casa perché piove.

Quick check

You can try choosing the best linker (perché, quindi, ma or però) for each sentence:

1. Resto a casa ___ piove.
2. Ho sete, ___ bevo un bicchiere d'acqua.
3. Mi piace Roma, ___ è molto caotica.
4. ___ non vieni alla festa? — ___ sono stanco.
5. Domani non lavoro, ___ vado al mare.
6. Anna è simpatica, ___ parla troppo.

Key takeaways

• Perché means why in a question and because when it gives a reason, and it is written with an acute accent: é.
• Quindi introduces the result: Piove, quindi resto a casa.
• Ma and però both show a contrast; ma starts its clause, while però can also follow the first word or phrase.
• The same two facts can be linked as reason, result or contrast, depending on what you mean.
• A comma often comes before ma, però and quindi.
