Λόγω της ακρίβειας στο σούπερ μάρκετ, αγοράζω λιγότερα γλυκά.

Λόγω means because of / due to.

In modern Greek, λόγω is a fixed preposition-like word, and it is normally followed by the genitive case:

• λόγω της βροχής = because of the rain
• λόγω του κρύου = because of the cold
• λόγω της ακρίβειας = because of the high prices / expensiveness

So in your sentence, λόγω της ακρίβειας means because of the high prices.

Because λόγω requires the genitive.

The basic dictionary form is:

• η ακρίβεια = expensiveness, high cost; also precision/accuracy in other contexts

But after λόγω, it changes to the genitive:

• της ακρίβειας

So:

• η ακρίβεια = the high cost / expensiveness
• λόγω της ακρίβειας = because of the high cost / because prices are high

This is a very common pattern in Greek: certain words and prepositions force a particular case.

Not here.

Ακρίβεια can mean two different things depending on context:

1. accuracy / precision
2. high prices / expensiveness / costliness

In the sentence λόγω της ακρίβειας στο σούπερ μάρκετ, it clearly means high prices.

This is a very useful word to remember, because in everyday Greek people often use η ακρίβεια to talk about the rising cost of living.

Στο is a contraction of:

• σε + το = στο

Here σε means in / at / to, and το is the neuter definite article the.

So:

• στο σούπερ μάρκετ = in/at the supermarket

This contraction is extremely common:

• σε + τον = στον
• σε + τη/την = στη(ν)
• σε + το = στο

It is a loanword from English, but it is fully normal in Greek.

Greek often treats σούπερ μάρκετ as a neuter noun, usually with the article το:

• το σούπερ μάρκετ = the supermarket

It is also generally indeclinable, meaning the noun itself does not change form much across cases. The article shows the grammar:

• το σούπερ μάρκετ
• στο σούπερ μάρκετ
• από το σούπερ μάρκετ

So the article changes as needed, while σούπερ μάρκετ stays the same.

Αγοράζω is the present tense form, meaning I buy / I am buying.

In this sentence, it most naturally expresses a habitual or general action:

• αγοράζω λιγότερα γλυκά = I buy fewer sweets

Greek present tense often works like English I buy for repeated or usual actions.

So the sentence is not just about one single shopping trip. It sounds like a general statement: because prices are high, I now buy fewer sweets.

Because λιγότερα agrees with γλυκά.

Here γλυκά is plural neuter, so the word meaning fewer / less must match it:

• masculine plural: λιγότεροι
• feminine plural: λιγότερες
• neuter plural: λιγότερα

Since we have:

• γλυκά = neuter plural

we need:

• λιγότερα γλυκά

This is a good example of adjective/quantifier agreement in Greek.

Because γλυκό as a noun is usually a neuter word.

Singular:

• το γλυκό = sweet / dessert

Plural:

• τα γλυκά = sweets / desserts

So in your sentence:

• λιγότερα γλυκά = fewer sweets

Even though γλυκός is also an adjective meaning sweet, here γλυκά is being used as a noun.

It can cover several similar ideas depending on context:

• sweets
• sweet things
• desserts
• sometimes candies

In a supermarket sentence, γλυκά is broad and natural. It does not point to just one exact English word. It simply means sweet food items.

So depending on the context, English could translate it as sweets, desserts, or even treats.

Because Greek often leaves out the article when speaking generally or indefinitely about things.

So:

• αγοράζω λιγότερα γλυκά = I buy fewer sweets

This sounds natural because it means sweets in general, not a specific known set of sweets.

If you added an article, it would sound more specific:

• αγοράζω λιγότερα από τα γλυκά = I buy fewer of the sweets
• αγοράζω τα λιγότερα γλυκά = I buy the fewest sweets

So the version without the article is the normal one here.

In this sentence, στο σούπερ μάρκετ most naturally goes with ακρίβειας:

• λόγω της ακρίβειας στο σούπερ μάρκετ
  = because of the high prices in the supermarket

So it tells you where the high prices are.

Of course, logically the buying also happens at the supermarket, but grammatically the phrase is mainly understood as modifying ακρίβειας here.

If you wanted to make the location of the buying more central, you could word the sentence differently.

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

The given sentence is perfectly natural:

• Λόγω της ακρίβειας στο σούπερ μάρκετ, αγοράζω λιγότερα γλυκά.

But Greek could also say something like:

• Αγοράζω λιγότερα γλυκά λόγω της ακρίβειας στο σούπερ μάρκετ.

Both mean essentially the same thing.

The original version puts the reason first, which gives it emphasis: Because of the high prices at the supermarket, I buy fewer sweets.

Grammatically, because γλυκά is a countable plural noun, English normally prefers fewer sweets.

Greek λιγότερα can correspond to English less or fewer, depending on what follows, but with a plural count noun like γλυκά, fewer is the best English match.

So:

• λιγότερα γλυκά = fewer sweets

It breaks down like this:

• Λόγω της ακρίβειας στο σούπερ μάρκετ = because of the high prices at the supermarket
• αγοράζω = I buy
• λιγότερα γλυκά = fewer sweets

So the pattern is:

Reason + main verb + object

A very literal structure would be:

• Because of the expensiveness in the supermarket, I buy fewer sweets.

A more natural English version is:

• Because of the high prices at the supermarket, I buy fewer sweets.
