Σε κάθε περίπτωση, θα σου στείλω μήνυμα.

Literally, Σε κάθε περίπτωση means in every case.

In natural English, it often comes out as:

• in any case
• anyway
• regardless

It is a very common set phrase in Greek for introducing something that will happen no matter what.

Breakdown:

• σε = in
• κάθε = each / every
• περίπτωση = case / situation

So the whole expression is quite close to the English logic.

Because κάθε means each / every, and in Greek it normally goes with a singular noun.

So:

• κάθε περίπτωση = each case / every case

This is similar to English:

• we say every case, not every cases

So the singular περίπτωση is exactly what you should expect here.

In Modern Greek, the future is usually formed with θα plus the verb.

Here:

• θα = future marker
• στείλω = verb form meaning send

So:

• θα στείλω = I will send

Greek does not form the future the same way English does with a separate verb like will plus the basic infinitive, because Modern Greek does not use infinitives in the same way. Instead, θα is followed by a finite verb form.

This is about aspect, which is very important in Greek.

• στέλνω = imperfective stem, used for ongoing, repeated, or habitual sending
• στείλω = perfective stem, used for a single complete action

In this sentence, the speaker means I will send you a message as one complete action, so Greek uses the perfective form:

• θα σου στείλω μήνυμα

If you said θα σου στέλνω μήνυμα, it would sound more like:

• I will be sending you messages
• I will send you a message regularly / repeatedly

So στείλω is the right choice for one message sent once.

σου means to you.

It is a weak object pronoun, very common in Greek. In this sentence it functions as the indirect object:

• θα σου στείλω μήνυμα = I will send you a message
• literally: I will to-you send message

Its position is also normal. In Greek, these short pronouns often come before the verb, and with θα they usually go between θα and the verb:

• θα σου στείλω

A fuller, more emphatic version would be something like:

• θα στείλω μήνυμα σε σένα

But the short pronoun σου is much more natural in ordinary speech.

Greek can use ένας / μία / ένα for a / an, but it does not have to.

So both of these are possible:

• θα σου στείλω μήνυμα
• θα σου στείλω ένα μήνυμα

The version without ένα is very natural and common. It simply means I’ll send you a message.

Adding ένα can make it a little more explicit or slightly more emphatic, but in many situations there is little difference.

Both are in the accusative singular.

Why?

• περίπτωση is accusative because it follows σε
  • σε κάθε περίπτωση
• μήνυμα is accusative because it is the direct object of στείλω
  • στείλω μήνυμα

So the grammar is:

• σε + accusative
• verb + direct object in the accusative

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

The sentence:

• Σε κάθε περίπτωση, θα σου στείλω μήνυμα.

is a very natural, neutral way to say it.

You could also hear variations like:

• Θα σου στείλω μήνυμα σε κάθε περίπτωση.
• Μήνυμα θα σου στείλω, σε κάθε περίπτωση.

But changing the order can change the focus or emphasis.

The original version puts Σε κάθε περίπτωση first, so it emphasizes:

• whatever happens
• in any case
• regardless

A simple pronunciation guide is:

Se KATHe peripTOSI, tha sou STEElo MEEneema.

More closely:

• Σε = se
• κάθε = KA-the (the th is like in think)
• περίπτωση = pe-REEP-to-see
• θα = tha (again, th as in think)
• σου = soo
• στείλω = STEE-lo
• μήνυμα = MEE-ni-ma

Stress falls on:

• κάθε
• περίπτωση
• στείλω
• μήνυμα

Not necessarily.

μήνυμα is a general word meaning message. Depending on context, it could mean:

• a text message
• a chat/app message
• a written message
• a message in general

If the context is phones or chatting, many people will naturally understand it as a text or digital message. But the word itself is broader than just text message.
