Deja de tocar el claxon, que ya puedo arrancar.

In Spanish, dejar de + infinitive is a very common structure meaning to stop doing whatever the infinitive says.

• dejar = to leave / to let
• dejar de
  • verb = to stop
    • verb-ing

So:

• Deja de tocar el claxon = Stop honking the horn

Other examples:

• Deja de gritar = Stop shouting
• Deja de hablar = Stop talking
• Deja de correr = Stop running

It is one of the most useful everyday patterns to learn.

Because deja is the tú imperative (informal singular command) of dejar.

The speaker is telling one person directly to do something:

• dejar = infinitive, to stop / to leave
• deja = stop! / leave! when speaking to tú

So:

• Deja de tocar el claxon = Stop honking the horn

If you were speaking more formally, you would say:

• Deje de tocar el claxon = Stop honking the horn

If you were speaking to several people in Spain:

• Dejad de tocar el claxon

It could. Both are natural, but they are not exactly the same structure.

• No toques el claxon = Don’t honk the horn
• Deja de tocar el claxon = Stop honking the horn

The difference is mostly this:

• No toques often sounds like don’t do it
• Deja de tocar suggests the action is already happening and the speaker wants it to stop

So in this sentence, deja de tocar el claxon makes good sense because the other person is presumably already honking.

Yes, tocar can mean to touch, but it also has other meanings, including to play an instrument and to sound something.

With vehicle horns, tocar el claxon means to honk / sound the horn.

So although the literal idea may look like touch the horn, the actual meaning here is idiomatic:

• tocar el claxon = to honk the horn

This is a good example of why literal word-for-word translation can be misleading.

Claxon means car horn in Spain.

A few useful notes:

• It is a masculine noun: el claxon
• In Spain, it is a normal everyday word
• In other Spanish-speaking countries, other words may be more common, such as bocina or corneta, depending on the region

So if you are learning Spanish from Spain, claxon is a very useful word to know.

Spanish often uses the definite article (el / la / los / las) where English might use a possessive like my, your, or his.

Here, the context already makes it clear which horn is meant, so Spanish naturally says:

• tocar el claxon

rather than:

• tocar tu claxon

Using tu claxon is possible, but it would sound more marked, as if you wanted to emphasize your horn specifically.

In this sentence, que introduces the reason or explanation for the command.

• Deja de tocar el claxon, que ya puedo arrancar.

Here, que is roughly like:

• because
• since
• now that

So the idea is:

• Stop honking the horn, because I can move off now.

This use of que is very common in spoken Spanish. It often connects two ideas in a natural, conversational way.

Ya is a very common word with meanings like:

• now
• already
• at this point

In this sentence, it suggests that the situation has changed and the speaker is now able to move:

• ya puedo arrancar = I can move off now / I can go now

Without ya, the sentence would still make sense:

• puedo arrancar

But ya adds the idea of finally or now it’s possible.

Here, arrancar means something like:

• to pull away
• to set off
• to move off
• to start driving

In driving contexts, arrancar can refer to starting movement, and sometimes also to starting the engine, depending on context.

In this sentence, because someone is honking and the speaker says ya puedo arrancar, the meaning is most naturally:

• I can pull away now
• I can set off now

So it is about the car being able to move.

Because Spanish often drops subject pronouns when they are obvious from the verb form.

• puedo already tells us the subject is yo
• so (yo) puedo arrancar is perfectly clear

That is why Spanish very often says:

• Puedo arrancar instead of
• Yo puedo arrancar

Adding yo is possible, but it usually adds emphasis or contrast.

Yes, it helps show the pause and the explanatory tone.

• Deja de tocar el claxon, que ya puedo arrancar.

The comma signals that the second part is giving the reason for the first part. In speech, you would usually hear a small pause there.

It is not just separating random clauses; it helps show this structure:

• command first
• explanation second

So the punctuation matches the natural spoken rhythm.

Yes. It is clearly informal singular because of deja.

The speaker is addressing one person as tú. That makes it suitable for:

• a friend
• a relative
• a partner
• someone you would normally address informally

If you wanted the formal version, you would say:

• Deje de tocar el claxon, que ya puedo arrancar.

So this is a good example of everyday, colloquial Spanish from Spain.

Yes, very easily.

The whole sentence can sound a bit impatient or annoyed, depending on tone:

• Deja de tocar el claxon already sounds like Stop it
• que ya puedo arrancar explains that the honking is unnecessary because the speaker is able to move now

So the overall feeling can be:

• Stop honking, I can go now
• There’s no need to keep honking

It is not rude in itself, but it can definitely sound irritated if said sharply.
