Σήμερα βρέχει συνεχώς, οπότε μένω σπίτι.

A natural word-by-word breakdown is:

• Σήμερα = today
• βρέχει = it rains / it is raining
• συνεχώς = continuously / constantly
• οπότε = so / therefore
• μένω = I stay / I am staying
• σπίτι = home

So the whole sentence means something like:

Today it’s raining constantly, so I’m staying home.

In Greek, weather verbs often work impersonally, so you usually do not need a subject like English it.

• Βρέχει. = It’s raining.
• Χιονίζει. = It’s snowing.

The -ει ending in βρέχει marks third person singular, but Greek does not need a separate subject pronoun here.

Βρέχει is in the present tense.

In Greek, the present tense can often translate as either:

• it rains
• it is raining

depending on context.

Here, because of Σήμερα and the situation being described right now, βρέχει is best understood as it is raining.

Συνεχώς is an adverb meaning continuously, constantly, or nonstop. It describes how it is raining.

So:

• βρέχει συνεχώς = it’s raining continuously

Its position is quite natural after the verb, though Greek word order is flexible. You may also hear other adverbs of frequency or manner in similar positions.

Here οπότε means so, therefore, or as a result. It connects the first idea to the consequence:

• Σήμερα βρέχει συνεχώς = the situation
• οπότε μένω σπίτι = the result

So it works like:

• It’s raining nonstop today, so I’m staying home.

In other contexts, οπότε can sometimes also relate to time or mean something closer to when, but in this sentence it clearly means so / therefore.

Μένω is also present tense.

Like βρέχει, the Greek present tense can often correspond to either:

• I stay
• I am staying

Context tells you which is more natural.

In this sentence, because the speaker is reacting to today’s weather, μένω σπίτι is naturally understood as:

I’m staying home.

Both can exist, but they are not exactly the same in feel.

• μένω σπίτι = I stay home / I’m staying home
• μένω στο σπίτι = I stay at the house / at home

In everyday Greek, σπίτι without an article is very common in expressions of location or destination, especially when it means home in a general sense.

So μένω σπίτι sounds very natural and idiomatic, much like English I’m staying home rather than I’m staying at home.

Yes. σπίτι here is in the accusative, but for this word the nominative and accusative forms are the same:

• nominative: το σπίτι
• accusative: το σπίτι

In expressions like μένω σπίτι, the article is dropped, but the form remains σπίτι.

Greek usually leaves out subject pronouns when they are not needed, because the verb ending already shows the person.

• μένω = I stay / I’m staying

The ending -ω tells you it is first person singular, so εγώ is unnecessary unless you want emphasis or contrast.

For example:

• Εγώ μένω σπίτι, αλλά αυτός βγαίνει. = I’m staying home, but he’s going out.

Yes, Greek word order is more flexible than English, although some versions sound more natural than others.

The original sentence:

• Σήμερα βρέχει συνεχώς, οπότε μένω σπίτι.

is very natural.

You might also hear variations such as:

• Βρέχει συνεχώς σήμερα, οπότε μένω σπίτι.
• Οπότε μένω σπίτι, αφού σήμερα βρέχει συνεχώς.
  (different structure, but similar idea)

Greek uses word order partly for focus and emphasis, not just grammar.

A rough pronunciation guide is:

• Σήμερα ≈ SEE-me-ra
• βρέχει ≈ VREH-hi
• συνεχώς ≈ see-ne-HOS
• οπότε ≈ o-PO-te
• μένω ≈ ME-no
• σπίτι ≈ SPEE-ti

Putting it together:

SEE-me-ra VREH-hi see-ne-HOS, o-PO-te ME-no SPEE-ti

A few notes:

• β sounds like v in Modern Greek.
• χ is a rough sound, like the ch in German Bach or Scottish loch.
• The accent marks show which syllable gets the stress.

The accent marks show which syllable is stressed.

For example:

• Σήμερα would be wrong
• Σήμερα is correct, with stress on -με-
• βρέχει is stressed on βρέ-
• μένω is stressed on μέ-

Stress is important in Greek because it is part of correct pronunciation and sometimes helps distinguish words.

Sometimes yes, depending on context.

In this sentence:

• βρέχει συνεχώς

the most direct translations are:

• it’s raining continuously
• it’s raining constantly
• it’s raining nonstop

All the time is possible in looser English, but continuously / nonstop is closer to the literal sense here.

Yes. The comma separates the first clause from the result clause introduced by οπότε.

So the structure is:

• statement: Σήμερα βρέχει συνεχώς
• result: οπότε μένω σπίτι

This punctuation is normal and helps clarity, much like English:

Today it’s raining nonstop, so I’m staying home.

Yes. That would also be very natural.

• οπότε μένω σπίτι = so I’m staying home
• γι’ αυτό μένω σπίτι = that’s why I’m staying home

They are close in meaning, but:

• οπότε feels like a connector meaning so / therefore
• γι’ αυτό more directly means for this reason / that’s why

Both are common in everyday Greek.

It follows a very common pattern:

time expression + situation + result

So:

• Σήμερα = time
• βρέχει συνεχώς = situation
• οπότε μένω σπίτι = result

This is a useful model for making your own sentences, for example:

• Σήμερα κάνει κρύο, οπότε μένω μέσα. = Today it’s cold, so I’m staying inside.

• Αύριο δουλεύω νωρίς, οπότε κοιμάμαι νωρίς. = Tomorrow I work early, so I’m going to bed early.
