Το μοσχάρι είναι πιο ακριβό από τον κιμά, γι’ αυτό σήμερα αγοράζω μόνο κιμά.

Because the two nouns have different grammatical genders, and κιμάς is also in a different case here.

• μοσχάρι is neuter, so in the nominative singular it takes το: το μοσχάρι
• κιμάς is masculine, and after από it appears in the accusative:
  ο κιμάς → τον κιμά

So the sentence uses:

• το μοσχάρι = the beef/veal
• από τον κιμά = than the minced meat

This is a normal pattern for masculine nouns ending in -άς.

The nominative singular is:

• ο κιμάς

But the accusative singular is:

• τον κιμά

So the final -ς drops in the accusative. You see the same kind of change with other nouns of this type.

In this sentence, κιμάς becomes κιμά because it follows από, which takes the accusative.

Because adjectives in Greek must agree with the noun they describe in gender, number, and case.

Here, ακριβό describes το μοσχάρι, which is:

• neuter
• singular
• nominative

So the adjective must also be neuter singular nominative:

• masculine: ακριβός
• feminine: ακριβή
• neuter: ακριβό

That is why the sentence has Το μοσχάρι είναι πιο ακριβό.

A very common way to make comparisons in Greek is:

• πιο + adjective + από

So:

• πιο ακριβό = more expensive
• από τον κιμά = than the minced meat

Together:

• πιο ακριβό από τον κιμά = more expensive than the minced meat

This pattern is extremely common and very useful in everyday Greek.

Yes. Both are correct.

You can express the comparative in two common ways:

• πιο ακριβό
• ακριβότερο

So these are both natural:

• Το μοσχάρι είναι πιο ακριβό από τον κιμά.
• Το μοσχάρι είναι ακριβότερο από τον κιμά.

In everyday speech, πιο + adjective is very common and often feels simpler for learners.

Here από means than, because it is part of a comparison.

So in this sentence:

• πιο ακριβό από τον κιμά = more expensive than minced meat

But από has other meanings too, especially from. Greek uses the same word in different contexts.

For example:

• Είμαι από την Ελλάδα. = I am from Greece.
• πιο μεγάλο από αυτό = bigger than that

So the meaning depends on the structure around it.

γι’ αυτό means for that reason, so, or that’s why.

In this sentence:

• γι’ αυτό σήμερα αγοράζω μόνο κιμά = that’s why today I’m buying only minced meat

The apostrophe appears because γι’ αυτό is a shortened form of για αυτό.

So:

• για αυτό → γι’ αυτό

This shortening is very common in normal written Greek.

Because Greek often omits the article with a direct object when speaking in a general or indefinite way, especially with food or material nouns.

So:

• αγοράζω μόνο κιμά = I’m buying only minced meat

This sounds like some minced meat / minced meat in general, not a specific previously identified portion.

If you said αγοράζω μόνο τον κιμά, it would sound more like I’m buying only the minced meat, referring to a specific one already known in the context.

So the absence of the article here is natural and meaningful.

αγοράζω is present tense, first person singular:

• αγοράζω = I buy / I am buying

In Greek, the present tense can often cover both ideas, depending on context:

• habitual: I buy
• right now / current situation: I am buying

In this sentence, because of σήμερα, it most naturally means something like:

• today I’m buying only minced meat
• or today I buy only minced meat

Because Greek word order is fairly flexible, and adverbs of time like σήμερα can move around.

Here:

• γι’ αυτό σήμερα αγοράζω μόνο κιμά

puts a little emphasis on today.

You could also hear:

• Γι’ αυτό αγοράζω μόνο κιμά σήμερα.

Both are understandable, but the original version feels very natural because it introduces the reason and then immediately highlights the time frame: today.

Not always exactly. Literally, μοσχάρι is related to calf, and in food contexts it can refer to veal or more generally beef, depending on context and usage.

So learners may see slightly different English translations. In a sentence about buying meat, what matters most is that μοσχάρι refers to a kind of meat, contrasted here with κιμάς.

That contrast is the key point:

• μοσχάρι = beef/veal
• κιμάς = minced meat / ground meat

μόνο means only.

It limits what the speaker is buying:

• αγοράζω μόνο κιμά = I’m buying only minced meat

So the idea is:

• beef/veal is more expensive than minced meat
• for that reason
• today
• I’m buying only minced meat

It is a very common word and works much like English only.
