Dikkat et, çayı üstüne dökme.

Dikkat et is a very common Turkish expression meaning Be careful or Pay attention.

Literally, it is made of:

• dikkat = attention, care
• et = do / make (the singular imperative of etmek)

So word-for-word, it is something like do attention, but in natural English that becomes pay attention or be careful.

Turkish often uses etmek with nouns to make verb-like expressions, and dikkat etmek is one of the most common examples.

Yes. Et is the singular imperative form of etmek.

That means the speaker is telling one person to do something:

• dikkat et = pay attention / be careful

If you were speaking to more than one person, or using a more polite form, you would say:

• dikkat edin

So in this sentence, et is definitely a command.

Because çayı is the definite direct object form.

• çay = tea
• çayı = the tea / this tea / that tea as a specific object

The suffix here is the accusative:

• çay
  • -ı → çayı

There is also a buffer letter y between the noun and the suffix, because the suffix starts with a vowel:

• çay-ı would sound awkward, so Turkish uses çay-y-ı, written çayı

In this sentence, the tea is a specific thing being referred to, so the accusative is natural.

Here, üstüne means something like onto you / on you / on top of you.

In this sentence, çayı üstüne dökmek means to spill the tea on yourself or on your clothes/body.

A useful thing to know is that Turkish often uses üstüne or üzerine in situations where English says:

• on
• onto
• on top of
• all over

So here the idea is not just the tea falling somewhere, but falling onto the person being addressed.

Because üstüne has a direction/target meaning: onto.

Compare:

• üstünde = on it / on him / on her in the sense of location
• üstüne = onto it / onto him / onto her in the sense of movement toward a target

Since spilling involves something going onto someone, üstüne is the right choice.

So:

• çay üstünde would suggest tea is already on top of something
• çayı üstüne dökme means don’t pour/spill the tea onto yourself

Good question. -me/-ma can do different jobs in Turkish, and here it is the negative imperative.

• dök = spill! / pour!
• dökme = don’t spill! / don’t pour!

So in this sentence:

• çayı üstüne dökme = don’t spill the tea on yourself

You are right that -me/-ma can also appear in verbal nouns, but here the form is clearly a command because of the context.

It is not stated, because Turkish usually leaves subject pronouns out when they are already understood.

The command form itself tells you the sentence is addressed to you:

• et = command to one person
• dökme = negative command to one person

So Turkish does not need to say sen here.

If you added sen, it would usually sound more emphatic:

• Sen dikkat et, çayı üstüne dökme.

But normally Turkish just leaves it out.

By itself, üstüne can mean onto him/her/it depending on context.

But in this sentence, because it is a warning directed at one person, the natural interpretation is:

• Don’t spill the tea on yourself
• or more literally, Don’t spill the tea onto your upper body/clothes

So the exact English wording depends on context, but the intended meaning is usually on yourself.

If the speaker wanted to make that extra explicit, they might say:

• kendi üstüne = onto yourself

But very often Turkish does not need that.

Yes, you could, and it would sound natural.

Compare:

• Dikkat et = pay attention / be careful
• Dikkatli ol = be careful

They are close in meaning, but dikkat et often sounds like a quick warning in the moment, while dikkatli ol can sound a little more like general advice about being careful.

So in this sentence:

• Dikkat et, çayı üstüne dökme. and
• Dikkatli ol, çayı üstüne dökme.

both work, but the first one is very common and very natural.

Not completely. Turkish word order is flexible, but different orders change the emphasis.

This version:

• çayı üstüne dökme

is very natural and neutral: Don’t spill the tea on yourself.

You could also hear:

• Üstüne çayı dökme

This puts a little more emphasis on onto yourself.

The verb usually comes at the end in Turkish, especially in neutral word order, so dökme staying at the end is the most typical pattern.
