Μετά τη διακοπή και την επανασύνδεση, η ηλεκτροδότηση συνεχίζεται.

In this sentence, μετά means after. When μετά is used in this sense in Modern Greek, it is followed by the accusative case.

So:

• μετά τη διακοπή = after the interruption/disconnection
• μετά την επανασύνδεση = after the reconnection

This is a very common pattern:

• μετά το μάθημα = after the lesson
• μετά τη δουλειά = after work

You may also see μετά από in other sentences, but here plain μετά + accusative is completely normal.

They are in the accusative because they depend on μετά, which here requires the accusative.

Both nouns are feminine singular:

• η διακοπή → accusative τη(ν) διακοπή
• η επανασύνδεση → accusative τη(ν) επανασύνδεση

The article changes form:

• nominative: η
• accusative: τη / την

So the case is not chosen because they are direct objects of a verb; it is chosen because they come after the preposition μετά.

This is about the final -ν in the feminine accusative article.

The full form is την, but in everyday Greek the -ν may be dropped before certain sounds. It is usually kept before vowels and certain consonants.

So:

• τη διακοπή: dropping the -ν is normal before δ
• την επανασύνδεση: the -ν is kept because the next word starts with a vowel, ε

This is very common:

• τη μέρα
• την ώρα

So both forms are normal; the choice depends on the sound that follows.

Greek often repeats the article with each noun in a coordinated phrase, especially in more careful or formal language.

So:

• τη διακοπή και την επανασύνδεση

is the most natural full form here.

You may sometimes see or hear one article covering both nouns in other contexts, but repeating it is very standard and clear. It helps show that both nouns are separate items in the list:

• the interruption
• the reconnection

The dictionary forms are:

• η διακοπή
• η επανασύνδεση

Both are feminine nouns ending in -ή / -ηση. They are abstract nouns formed from verbal ideas:

• διακοπή = interruption, stopping, disconnection
• επανασύνδεση = reconnection, reconnecting

In this sentence they refer to events or processes, not people or objects.

Because it is the subject of the verb συνεχίζεται.

The structure is:

• Μετά τη διακοπή και την επανασύνδεση = after the interruption and the reconnection
• η ηλεκτροδότηση = the power supply / electrification / electricity supply
• συνεχίζεται = continues / is continued

Since η ηλεκτροδότηση is the thing that continues, it appears in the nominative case, which is the normal case for the subject.

Literally, η ηλεκτροδότηση means something like electrification or electricity supply. In context, it usually means the supply of electricity / power supply.

So depending on the setting, it could refer to:

• electricity being supplied to a building
• restoring electrical service
• the power feed in a system

This is a more formal or technical word than simply το ρεύμα, which often means electricity / power in everyday speech.

συνεχίζεται is the present tense, third person singular, from the verb συνεχίζομαι / συνεχίζεται in this kind of passive or middle-style use.

Here it means:

• continues
• or more literally is continued

In natural English, continues is usually the best translation.

Examples of the same pattern:

• Η λειτουργία συνεχίζεται. = The operation continues.
• Η διαδικασία συνεχίζεται. = The process continues.

So in your sentence, η ηλεκτροδότηση συνεχίζεται means that the power supply continues after the interruption and reconnection.

Formally, it has a passive/middle ending: -εται. But in meaning, it often works like an intransitive verb in English: continues.

So although it looks passive, you should not always translate it with is continued. In many contexts, the most natural English is simply:

• continues

This is very common in Greek. Many verbs with passive-style endings do not always feel strongly passive in translation.

The comma separates the introductory time phrase from the main clause.

So the sentence is divided into:

• Μετά τη διακοπή και την επανασύνδεση,
• η ηλεκτροδότηση συνεχίζεται.

This is similar to English punctuation in a sentence like:

• After the interruption and reconnection, the power supply continues.

The comma helps readability, especially in formal written Greek.

Yes. Greek word order is more flexible than English, although not random.

This sentence uses a very natural formal order:

• Μετά τη διακοπή και την επανασύνδεση, η ηλεκτροδότηση συνεχίζεται.

But you could also find variants such as:

• Η ηλεκτροδότηση συνεχίζεται μετά τη διακοπή και την επανασύνδεση.

This would still be grammatical and would sound natural too. The original version puts the time condition first, which is common in formal notices and instructions.

A rough pronunciation guide is:

• Μετά = meh-TA
• τη διακοπή = tee thee-ah-koh-PEE
• και = keh
• την επανασύνδεση = teen eh-pah-nah-SEEN-theh-see
• η ηλεκτροδότηση = ee ee-lek-troh-thoh-TEE-see
• συνεχίζεται = see-neh-khee-ZEH-teh

A few useful notes:

• δ sounds like th in this
• θ sounds like th in think
• χ is a rough sound, like the ch in German Bach or Scottish loch
• Stress matters a lot in Greek, so pay attention to the accented syllables:
  • μετά
  • διακοπή
  • επανασύνδεση
  • ηλεκτροδότηση
  • συνεχίζεται

Yes, it sounds fairly formal or technical. It fits well in contexts such as:

• utility notices
• technical instructions
• official announcements
• electrical service information

In more everyday speech, someone might use simpler words, for example with ρεύμα instead of ηλεκτροδότηση, depending on context. But the sentence as given is perfectly normal Greek, especially in formal writing.
