Αυτή την εποχή η ακρίβεια στο σούπερ μάρκετ είναι μεγάλο πρόβλημα, αλλά δεν θέλω να θυσιάζω την ποιότητα του φαγητού.

Αυτή την εποχή means at this time / these days / currently.

Grammatically, αυτή and την εποχή are in the accusative feminine singular:

• αυτή = this
• την εποχή = the time / the period

In Greek, certain time expressions use the accusative to mean during / at a certain time:

• αυτή την εβδομάδα = this week
• αυτή τη στιγμή = right now
• αυτή την εποχή = these days / at this time

So even though English does not show a special case here, Greek does.

Yes, ακρίβεια can mean accuracy, but it also very commonly means high prices / expensiveness / the cost-of-living problem, depending on context.

In this sentence:

• η ακρίβεια στο σούπερ μάρκετ means something like the high cost of groceries / rising prices at the supermarket

This is a very common modern use in Greek. So the word has two important meanings:

1. accuracy / precision
2. expensiveness / high prices

The context tells you which one is meant.

Because στο is the contracted form of:

• σε + το = στο

This is completely normal in Greek. Similar contractions are:

• σε + τη(ν) = στη(ν)
• σε + τα = στα
• σε + τους = στους

So:

• στο σούπερ μάρκετ = in/at the supermarket

Greek almost always uses these contracted forms in everyday language.

Because πρόβλημα is a neuter noun.

So the adjective must also be neuter singular:

• μεγάλος = masculine
• μεγάλη = feminine
• μεγάλο = neuter

Since πρόβλημα is neuter, we say:

• μεγάλο πρόβλημα = a big problem

Even though many nouns ending in -α are feminine, πρόβλημα is one of many neuter nouns ending in -μα.

Greek can use a noun without the indefinite article because Greek does not have a separate word for a/an like English does.

So:

• είναι μεγάλο πρόβλημα literally = is big problem
• natural English = is a big problem

Greek often leaves the noun without an article when English would use a/an.

Compare:

• Είναι γιατρός. = He/She is a doctor.
• Είναι καλό παιδί. = He/She is a good kid.
• Είναι μεγάλο πρόβλημα. = It is a big problem.

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

After να, Greek often chooses between:

• imperfective verb form: ongoing, repeated, habitual
• perfective verb form: one whole action, a single event, completion

Here:

• θυσιάζω = imperfective
• θυσιάσω = perfective subjunctive form after να

So:

• δεν θέλω να θυσιάζω την ποιότητα suggests
  I don’t want to be sacrificing / keep sacrificing the quality
  or more naturally, I don’t want to sacrifice the quality

It emphasizes a repeated or general situation.

If you said:

• δεν θέλω να θυσιάσω την ποιότητα that would sound more like:
• I don’t want to sacrifice the quality (in this instance / as a complete act)

Both can be possible depending on nuance, but θυσιάζω fits very well here because the sentence is about an ongoing everyday issue.

Yes, historically it is similar to I want to..., but in modern Greek θέλω να + verb is the normal way to say want to do something.

So:

• θέλω να φύγω = I want to leave
• θέλω να φάω = I want to eat
• δεν θέλω να θυσιάζω... = I don’t want to sacrifice...

The word να introduces the dependent verb form. You do not translate it literally every time, but it is essential in Greek grammar.

Την ποιότητα is in the accusative feminine singular because it is the direct object of θυσιάζω.

The verb θυσιάζω means to sacrifice, and what is being sacrificed is:

• την ποιότητα = the quality

So:

• θυσιάζω την ποιότητα = I sacrifice the quality

The nominative form is:

• η ποιότητα

The accusative form is:

• την ποιότητα

For this noun, the noun itself stays the same, but the article changes:

• η → την

Του φαγητού is the genitive singular of το φαγητό.

It means:

• of the food

So:

• η ποιότητα του φαγητού = the quality of the food

This is a very common Greek structure:

• το χρώμα του αυτοκινήτου = the color of the car
• η τιμή του ψωμιού = the price of the bread
• η ποιότητα του φαγητού = the quality of the food

In English, we often use of. In Greek, this relationship is often shown by the genitive case.

It is the genitive singular form of φαγητό:

• nominative: το φαγητό
• genitive: του φαγητού

The stress moves in the genitive because of Greek stress rules. This is normal for many neuter nouns in -ό:

• το παιδί → του παιδιού
• το βουνό → του βουνού
• το φαγητό → του φαγητού

So it may feel irregular at first, but it is actually part of a common pattern.

Σούπερ μάρκετ is a loanword from English. Many such borrowed words in Greek are:

• used very commonly
• often treated as indeclinable or only minimally changed

So in everyday speech you will hear:

• το σούπερ μάρκετ
• στο σούπερ μάρκετ

The article changes, but the borrowed noun itself usually stays the same.

Yes. Greek word order is more flexible than English because case endings and articles help show grammatical roles.

The sentence as given sounds natural:

• Αυτή την εποχή η ακρίβεια στο σούπερ μάρκετ είναι μεγάλο πρόβλημα, αλλά δεν θέλω να θυσιάζω την ποιότητα του φαγητού.

It starts with a time expression, which sets the scene:

• these days / at this time

Greek could rearrange parts for emphasis, for example:

• Η ακρίβεια στο σούπερ μάρκετ είναι μεγάλο πρόβλημα αυτή την εποχή...

That would still be grammatical, but the emphasis would be slightly different. The original version feels very natural because it begins with the general frame: these days.

Usually, yes. Αλλά is the standard Greek word for but.

In this sentence it connects two ideas:

1. prices are a big problem
2. I do not want to sacrifice food quality

So:

• ..., αλλά ... = ..., but ...

It is one of the most common conjunctions in Greek.

Δεν is the standard negation used before verbs in many everyday sentences.

So:

• θέλω = I want
• δεν θέλω = I do not want

Greek normally places δεν right before the verb:

• Δεν ξέρω. = I don’t know.
• Δεν μπορώ. = I can’t.
• Δεν θέλω να φύγω. = I don’t want to leave.

There is also μη(ν), but that is used in different contexts, such as prohibitions or certain subordinate structures. In this sentence, δεν is the correct choice.
