Διάβασε προσεκτικά την προειδοποίηση.

Διάβασε is the imperative form of the verb διαβάζω (to read).

In this sentence, it means Read! and it is:

• singular: said to one person
• informal
• perfective/aorist imperative: it tells someone to complete the action

So Διάβασε προσεκτικά την προειδοποίηση. is the kind of command you would give when you want someone to read the warning through.

A very useful comparison is:

• Διάβασε = Read it / Read it through
• Διάβαζε = Be reading / Read habitually / Keep reading

In commands like this, Greek usually uses the aorist imperative when the action is seen as a whole.

Because this sentence is a command, not a statement.

Compare:

• διαβάζω = I read / I am reading
• διαβάζεις = you read / you are reading
• διάβασε = read!

So:

• διαβάζω την προειδοποίηση = I read the warning
• διαβάζεις την προειδοποίηση = you are reading the warning
• διάβασε την προειδοποίηση = read the warning!

English often uses the plain verb form for commands, and Greek does something similar, but with a specific imperative form.

Προσεκτικά is an adverb, not an adjective. It means carefully.

It comes from the adjective:

• προσεκτικός = careful (masculine)
• προσεκτική = careful (feminine)
• προσεκτικό = careful (neuter)

The adverb is:

• προσεκτικά = carefully

So:

• είναι προσεκτικός = he is careful
• διάβασε προσεκτικά = read carefully

A common pattern in Greek is that adverbs are formed with -ά or -ώς, depending on the word.

Την is the definite article meaning the, and here it is:

• feminine
• singular
• accusative

It is used because προειδοποίηση (warning) is a feminine noun, and it is the direct object of the verb Διάβασε.

So:

• η προειδοποίηση = the warning (subject form / nominative)
• την προειδοποίηση = the warning (object form / accusative)

English uses the for both, but Greek changes the article depending on the noun’s role in the sentence.

Good question. In this case, the noun does happen to look the same in the nominative and accusative singular.

For this noun:

• η προειδοποίηση = the warning (nominative)
• την προειδοποίηση = the warning (accusative)

So the article changes clearly:

• η → nominative
• την → accusative

But the noun itself stays προειδοποίηση in both forms.

This is normal for many feminine nouns ending in -ηση, -ση, -ξη, and similar patterns.

It is in the accusative case because it is the direct object of the verb Διάβασε.

Ask yourself: Read what? Answer: the warning

That makes the warning the direct object, and in Greek direct objects typically go in the accusative.

So:

• verb: Διάβασε
• direct object: την προειδοποίηση

This is one of the most common uses of the accusative in Greek.

The given order is natural and standard, but Greek word order is more flexible than English.

You may also hear:

• Διάβασε την προειδοποίηση προσεκτικά.
• Την προειδοποίηση διάβασε προσεκτικά.

These all mean roughly the same thing, but the emphasis changes:

• Διάβασε προσεκτικά την προειδοποίηση. = neutral, natural
• Διάβασε την προειδοποίηση προσεκτικά. = also very natural
• Την προειδοποίηση διάβασε προσεκτικά. = puts extra focus on the warning

So the original sentence is not the only possible order, just a very normal one.

You would use Διαβάστε instead of Διάβασε.

So:

• Διάβασε προσεκτικά την προειδοποίηση. = Read the warning carefully.
  (to one person, informal)

• Διαβάστε προσεκτικά την προειδοποίηση. = Read the warning carefully.
  (to more than one person, or to one person formally)

This is a very important distinction in Greek:

• Διάβασε = singular informal command
• Διαβάστε = plural or polite/formal command

Yes, stress matters a lot in Greek. The accent mark shows which syllable is stressed.

• Διάβασε is stressed on Διά-
• προειδοποίηση is stressed on -ποί-

Roughly:

• Διά-βα-σε
• προ-ει-δο-ποί-η-ση

If you put the stress in the wrong place, people may still understand you from context, but it will sound incorrect and can sometimes cause confusion.

Greek spelling normally marks stress clearly, which is very helpful for learners.

Yes. Προειδοποίηση means warning, and it is related to the verb:

• προειδοποιώ = to warn

So:

• προειδοποιώ = I warn
• προειδοποίηση = warning

You can often spot this noun pattern in Greek:

• verb ending in -ώ
• related noun ending in -ηση or similar

So if you already know προειδοποιώ, it is easier to remember προειδοποίηση.

Yes, absolutely. It sounds very natural, especially in contexts like:

• labels
• safety instructions
• manuals
• signs
• official notices

For example, on packaging or a warning sign, Greek often uses short imperative instructions like this.

So Διάβασε προσεκτικά την προειδοποίηση. is grammatically normal and very believable in real life.
