Βρέχει συνέχεια σήμερα.

• Βρέχει = it rains / it is raining
• συνέχεια = continuously / all the time
• σήμερα = today

So the structure is basically verb + adverb + time word.

Greek often does not use a dummy subject like English it in weather expressions.

So English says It is raining, but Greek simply says Βρέχει.

The verb ending already shows that it is 3rd person singular, and with weather verbs that is enough. There is no need to add a separate word for it.

Yes, βρέχει is present tense.

In Greek, the present can cover both:

• it rains
• it is raining

The context tells you which one is meant. In this sentence, because of σήμερα and συνέχεια, the natural sense is ongoing: it’s raining continuously today or it keeps raining today.

Literally, συνέχεια is a noun that can mean things like continuation or continuity.

But in everyday Greek it is also very commonly used adverbially, meaning:

• continuously
• constantly
• all the time

So in this sentence, it is acting like an adverb, even though its basic form is a noun.

Both are possible, but they feel slightly different in style.

• συνέχεια is very common in everyday spoken Greek.
• συνεχώς also means continuously, but can sound a bit more formal or more neutral/written.

So Βρέχει συνέχεια σήμερα. sounds natural and conversational.

Yes. Greek word order is more flexible than English word order.

You could also say:

• Σήμερα βρέχει συνέχεια.
• Βρέχει σήμερα συνέχεια.

These all mean roughly the same thing, but the emphasis changes a little.

• Βρέχει συνέχεια σήμερα. puts the focus first on it’s raining
• Σήμερα βρέχει συνέχεια. puts today first, which can sound slightly more neutral in many contexts

So the original sentence is correct and natural, but it is not the only possible order.

The dictionary form is βρέχω.

That verb can mean:

• to wet / to make wet
• and in the impersonal weather use, to rain

In actual speech, for weather, learners very often meet the form βρέχει first, because that is the form used in sentences like this one.

A rough English-friendly guide is:

VREH-hyi see-NEH-hya SEE-meh-ra

A few useful notes:

• β sounds like English v
• χ here is not English ch as in church
• before ε or ι, χ is a softer sound, a bit like the h-type sound in German ich
• the stress falls on:
  • ΒΡΕ-χει
  • συ-ΝΕ-χεια
  • ΣΗ-μερα

Yes. It is a complete, natural everyday sentence.

Greek weather expressions often consist of just the verb plus any extra information, such as:

• Βρέχει. = It’s raining.
• Βρέχει συνέχεια. = It’s raining all the time.
• Βρέχει συνέχεια σήμερα. = the full sentence here

So nothing is missing. It sounds normal as it is.
