Ο κίνδυνος είναι μεγαλύτερος όταν ο δρόμος είναι βρεγμένος.

Ο is the masculine singular definite article, meaning the.

It is used because κίνδυνος is:

• masculine
• singular
• in the nominative case

So ο κίνδυνος means the danger.

Also, Greek uses the definite article more often than English, even in general statements.

κίνδυνος is the nominative singular form of the noun, which is the form used for the subject of the sentence.

In this sentence, the danger is the subject:

• Ο κίνδυνος = the danger
• είναι = is
• μεγαλύτερος = greater

So the subject must be in the nominative.

Because it agrees with κίνδυνος.

In Greek, adjectives must agree with the noun they describe in:

• gender
• number
• case

Since κίνδυνος is masculine singular nominative, μεγαλύτερος is also masculine singular nominative.

Compare:

• ο κίνδυνος είναι μεγαλύτερος = the danger is greater
• η δυσκολία είναι μεγαλύτερη = the difficulty is greater
• το πρόβλημα είναι μεγαλύτερο = the problem is greater

μεγαλύτερος is the comparative form of μεγάλος (big, large, great).

So:

• μεγάλος = big / great
• μεγαλύτερος = bigger / greater

In this sentence, greater is the most natural translation.

Greek often forms comparatives like this with -ότερος / -ύτερος type endings, though another very common way is with πιο:

• μεγαλύτερος
• πιο μεγάλος

Both can mean bigger / greater, though μεγαλύτερος is a single-word comparative.

Yes. Greek could say:

Ο κίνδυνος είναι πιο μεγάλος όταν ο δρόμος είναι βρεγμένος.

That is also natural and correct.

In many situations:

• μεγαλύτερος = more formal or compact
• πιο μεγάλος = very common in everyday speech

In this sentence, μεγαλύτερος sounds completely normal.

Because there are two separate clauses, and each one has its own verb:

1. Ο κίνδυνος είναι μεγαλύτερος
   = the danger is greater

2. όταν ο δρόμος είναι βρεγμένος
   = when the road is wet

So Greek keeps είναι in both clauses, just as English uses is in both parts:

• the danger is greater
• the road is wet

όταν means when.

It introduces a time clause:

• όταν ο δρόμος είναι βρεγμένος = when the road is wet

Unlike English, where learners sometimes expect a special tense pattern, Greek simply uses the verb normally here. In this sentence, είναι is in the present tense because it expresses a general condition.

So the full idea is:

• whenever the road is wet, the danger is greater

Because δρόμος is also a masculine singular noun, so it takes the article ο.

• ο δρόμος = the road

Again, Greek often uses the definite article in places where English may or may not use it. Here it is perfectly natural to say ο δρόμος.

βρεγμένος literally means wet or soaked, but grammatically it is a past participle used as an adjective.

It comes from the verb βρέχω = to wet / to rain.

So:

• βρεγμένος δρόμος = a wet road
• literally, something like a road that has become wet

This is very common in Greek. Participles often function like ordinary adjectives.

It is nominative masculine singular, because it agrees with ο δρόμος.

The structure is:

• ο δρόμος = subject
• είναι = is
• βρεγμένος = wet

After είναι, Greek uses the adjective in the form that matches the subject.

So:

• ο δρόμος είναι βρεγμένος
• masculine, singular, nominative

Not exactly.

Both can relate to wetness, but they are used a bit differently:

• βρεγμένος = wet, having gotten wet
• υγρός = damp, moist, humid

For a road after rain, βρεγμένος is very natural:

• ο δρόμος είναι βρεγμένος = the road is wet

υγρός would sound less direct here and may suggest dampness rather than a clearly rain-wet surface.

Yes, Greek word order is more flexible than English, although not every version sounds equally neutral.

The given sentence:

• Ο κίνδυνος είναι μεγαλύτερος όταν ο δρόμος είναι βρεγμένος.

This is the most straightforward, neutral order.

You could also hear variations such as:

• Όταν ο δρόμος είναι βρεγμένος, ο κίνδυνος είναι μεγαλύτερος.

That version puts more emphasis on the condition first:

• When the road is wet, the danger is greater.

So yes, the order can change, but the original sentence is very natural and clear.

A rough pronunciation is:

me-gha-LI-te-ros

More accurately:

• με = meh
• γα = gha
• λύ = LEE
• τε = teh
• ρος = ros

The stress is on λύ:

• μεγαΛΥτερος

A few pronunciation notes:

• Greek γ here is not a hard English g as in go
• it is a softer sound, like a voiced throat/fricative sound

It can function as a general statement, even though Greek uses the definite article:

• ο κίνδυνος
• ο δρόμος

Greek often uses the definite article in general truths or general observations where English may sound more generic.

So the sentence naturally means something like:

• danger is greater when the road is wet
• the danger is greater when the road is wet

In practice, it is understood as a general statement, not necessarily about one single specific road.
