Η συρρίκνωση γίνεται στην όπτηση.

It breaks down like this:

• Η συρρίκνωση = the subject
• γίνεται = the verb
• στην όπτηση = a prepositional phrase telling you when / in what process it happens

So the structure is:

article + noun + verb + prepositional phrase

Greek often allows more flexible word order than English, but this is a very natural, neutral way to say it.

Η is the feminine singular definite article, meaning the.

It agrees with συρρίκνωση, which is a feminine singular noun.

So:

• η = the for feminine singular nouns
• συρρίκνωση = a feminine singular noun

Together, Η συρρίκνωση means the shrinkage.

Also, note that Η here is just the article; in Modern Greek it is pronounced i, not like English h.

Συρρίκνωση is a noun. It refers to the process or result of becoming smaller, such as shrinkage, contraction, or reduction, depending on context.

A learner may also notice that it ends in -ωση, which is a very common noun ending in Greek for process/result nouns, similar to English endings like -tion in some cases.

Grammatically here it is:

• feminine
• singular
• nominative case because it is the subject of the sentence

Γίνεται comes from γίνομαι, which often means:

• to become
• to happen
• to take place
• to be done / occur, depending on context

In this sentence, it does not mean becomes in the usual sense. It means something more like:

• happens
• occurs
• takes place

So Η συρρίκνωση γίνεται... means that the shrinkage occurs or takes place during that process.

This is very natural Greek. English often prefers a verb like occurs, while Greek often uses γίνομαι in contexts where English would not use become.

It looks like a middle/passive form, and historically it is connected with that system, but for a learner the most useful thing is this:

γίνομαι is a very common verb that is used as a normal dictionary verb in this form.
So γίνεται should usually be learned as the present-tense form of γίνομαι, not as if it were simply a passive version of some active verb you need here.

In this sentence, it means occurs / happens / takes place, not is being made.

Στην is the usual contraction of:

• σε = in / at / to
• την = the (feminine singular accusative)

So:

• σε την όπτηση → στην όπτηση

This contraction is extremely common and completely standard in Modern Greek.

You should think of στην as meaning:

• in the
• during the
• sometimes at the, depending on context

After σε / στη(ν), Greek normally uses the accusative case.

So in στην όπτηση:

• στην already contains the accusative feminine article την
• όπτηση is therefore in the accusative singular

For many feminine nouns, the nominative and accusative forms can look the same, and that is exactly what happens here:

• nominative: η όπτηση
• accusative: την όπτηση

The noun itself stays the same in form; the article shows the case clearly.

Όπτηση refers to firing, especially in technical contexts such as:

• ceramics
• clay
• industrial heating processes
• materials processing

So this is not everyday baking in the kitchen sense. It is a more technical word for heating material at high temperature as part of a manufacturing or treatment process.

That is why στην όπτηση is best understood as during firing or in the firing stage/process.

In Greek, σε can cover several meanings that English splits into different prepositions.

So στην όπτηση can be understood in English as:

• in the firing process
• during firing
• at the firing stage

Which English version sounds best depends on the technical context. Greek itself is perfectly natural here and does not sound odd.

A simple pronunciation guide is:

i sir-RIK-no-si GHEE-ne-te stin OP-ti-si

A few helpful notes:

• η sounds like ee
• συρρίκνωση is stressed on ρί
• γίνεται is stressed on γί
• στην is pronounced as one word
• όπτηση is stressed on ό

If you want a more careful approximation:

• Η = ee
• συρρίκνωση = see-REEK-no-see or sir-REEK-no-see depending on how closely you imitate Greek vowel quality
• γίνεται = YEE-ne-te or GHEE-ne-te depending on how you represent Greek γ
• στην = steen
• όπτηση = OP-ti-see

Yes. Greek word order is more flexible than English because case endings and articles help show what each word is doing.

For example, this sentence could be rearranged for emphasis, such as:

• Στην όπτηση γίνεται η συρρίκνωση.

That would put more focus on the firing stage.

But Η συρρίκνωση γίνεται στην όπτηση is the most straightforward, neutral version.

Yes. Γίνεται is present tense, and here it expresses a general truth or process description.

So the sentence is not necessarily talking about one specific event happening right now. It is more like a technical statement:

• this is what happens in the process
• this is the stage where shrinkage occurs

That use of the present tense is very common in Greek, just as it is in English when describing scientific or technical facts.
