Η προδιαμόρφωση γίνεται πριν από την τελική διαμόρφωση.

Γίνεται is from γίνομαι, a very common verb that can mean several things depending on context, including:

• become
• happen
• take place
• be done / be carried out

In this sentence, γίνεται does not mean becomes. It means something more like:

• takes place
• is done
• is carried out

So the sentence is understood as:

• The preforming / pre-shaping is done before the final forming / shaping.

This is a very common thing for learners to notice: γίνομαι often has a broader meaning than just become.

Η is the feminine singular definite article, meaning the.

So:

• η προδιαμόρφωση = the preforming / pre-shaping

Greek articles show gender, number, and case, so they change form depending on the noun’s role in the sentence.

Here, προδιαμόρφωση is a feminine singular noun, and it is the subject of the sentence, so it takes the nominative article η.

Because this noun phrase comes after the preposition πριν από, which takes the accusative case.

So:

• nominative: η τελική διαμόρφωση
• accusative: την τελική διαμόρφωση

That is why both the article and the adjective appear in the accusative form:

• την = the (feminine singular accusative)
• τελική = final (feminine singular accusative)
• διαμόρφωση = formation/shaping (same form here as nominative)

A useful point: some feminine nouns in -ηση / -ωση look the same in nominative and accusative singular, so the article is what makes the case especially clear.

Πριν από means before.

It is a very common expression in Greek. In this sentence it introduces a noun phrase:

• πριν από την τελική διαμόρφωση = before the final shaping

Even though από by itself often means from, in the fixed expression πριν από, the whole phrase simply means before.

You can think of it as one unit here.

Yes, in modern Greek you will often hear and see:

• πριν την τελική διαμόρφωση

instead of:

• πριν από την τελική διαμόρφωση

Both are used.
In more careful or formal phrasing, πριν από is often preferred before a noun phrase.
In everyday speech, omitting από is very common.

So both can be correct depending on style and register.

Because it has to agree with διαμόρφωση, which is a feminine noun.

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

• gender
• number
• case

So:

• τελικός = masculine
• τελική = feminine
• τελικό = neuter

Since διαμόρφωση is feminine singular, the adjective must also be feminine singular:

• τελική διαμόρφωση = final shaping

And because the phrase is in the accusative after πριν από, we get:

• την τελική διαμόρφωση

Because προδιαμόρφωση is built from the same base noun διαμόρφωση with the prefix προ-.

So:

• διαμόρφωση = formation, shaping, forming
• προ- = pre-, before
• προδιαμόρφωση = preformation, pre-shaping, preforming

This kind of word-building is very common in Greek. Once you recognize prefixes, long words become much easier to understand.

Other examples of προ- are:

• πρόγραμμα = program
• προετοιμασία = preparation
• προϊστορία = prehistory

So here the idea is literally something like pre-shaping before the final shaping.

Not exactly in the same way English uses a regular passive like is shaped.

The verb γίνεται comes from γίνομαι, not from a passive form of κάνω or διαμορφώνω. It often gives an impersonal or process-oriented meaning such as:

• takes place
• is done
• occurs

So the sentence focuses on the process, not on who performs it.

A natural English translation might be:

• Preforming is done before the final forming.
• The pre-shaping takes place before the final shaping.

So it has a passive-like feel in English, but grammatically it is built with γίνεται.

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

The sentence as written is very natural:

• Η προδιαμόρφωση γίνεται πριν από την τελική διαμόρφωση.

This presents the topic first, then the verb, then the time relation.

But Greek could change the order for emphasis, for example:

• Πριν από την τελική διαμόρφωση γίνεται η προδιαμόρφωση.

This would emphasize before the final shaping first.

Even though Greek allows more flexibility, the original version is clear and neutral.

Greek uses the definite article more often than English, especially with nouns referring to known processes, categories, or general concepts in a specific context.

So:

• Η προδιαμόρφωση = the preforming
• την τελική διαμόρφωση = the final forming

In English, depending on context, you might or might not use the.
In Greek, using the article here sounds normal and natural.

This is something English speakers often have to get used to: Greek articles are used very frequently.

A rough pronunciation guide is:

• Η προδιαμόρφωση γίνεται πριν από την τελική διαμόρφωση
• ee pro-thia-MOR-fo-see YEE-ne-te prin a-PO teen te-lee-KEE thia-MOR-fo-see

A few helpful notes:

• η sounds like ee
• γ before ε in γίνεται sounds like a soft sound, roughly like y in this kind of approximation
• δ sounds like th in this
• θ sounds like th in think
• the stress is important:
  • προδιαμόρφωση
  • γίνεται
  • από
  • τελική
  • διαμόρφωση

A very literal breakdown is:

• Η προδιαμόρφωση = the pre-shaping
• γίνεται = takes place / is done
• πριν από = before
• την τελική διαμόρφωση = the final shaping

So, word-for-word:

• The pre-shaping takes place before the final shaping.

This is a useful way to see the grammar, even if a smoother English translation might be slightly different depending on the technical context.

It is a noun.

Specifically, διαμόρφωση means something like:

• formation
• shaping
• configuration
• forming

It comes from the verb διαμορφώνω, meaning:

• to shape
• to form
• to configure

So:

• διαμορφώνω = verb
• διαμόρφωση = noun

Likewise:

• προδιαμόρφωση is also a noun

That is why the sentence is about one process happening before another process, rather than directly saying someone shapes something.
