Για πρωινό τρώω βρώμη με λίγο μέλι, αλλά η αδερφή μου θέλει σολομό με ψωμί το μεσημέρι.

Για πρωινό literally means for breakfast.

Greek often uses για + noun to say what something is for or as:

• Για πρωινό τρώω... = For breakfast, I eat...

It is a very natural way to introduce a meal. English might also say For breakfast, I eat..., so the structure matches fairly well here.

Τρώω is the present tense of to eat.

In this sentence, the present tense is being used for a habit or routine:

• Για πρωινό τρώω βρώμη... = I eat oatmeal for breakfast / I have oatmeal for breakfast

Greek uses the present tense this way just like English does:

• I drink coffee in the morning
• Πίνω καφέ το πρωί

Βρώμη literally means oats or oatmeal, depending on context.

In a food sentence like this, it usually means:

• oatmeal
• oats

Greek often uses the singular noun βρώμη, even though English commonly says oats in the plural.

Because μέλι is a neuter noun.

The word λίγος, λίγη, λίγο changes form to agree with the noun:

• masculine: λίγος
• feminine: λίγη
• neuter: λίγο

Since μέλι is neuter, Greek uses λίγο:

• λίγο μέλι = a little honey

Compare:

• λίγη ζάχαρη = a little sugar because ζάχαρη is feminine

Με means with.

So:

• βρώμη με λίγο μέλι = oatmeal with a little honey
• σολομό με ψωμί = salmon with bread

It is a very common preposition in Greek.

In Greek, possessive phrases usually take the definite article:

• η αδερφή μου = my sister
• ο φίλος μου = my friend
• το σπίτι μου = my house

This is different from English, where we do not use the:

• English: my sister
• Greek: the sister my

So η αδερφή μου is the normal Greek pattern.

Greek possessive pronouns like μου (my) usually come after the noun:

• η αδερφή μου = my sister
• το βιβλίο μου = my book

This is one of the basic word-order differences between Greek and English.

Θέλει means he/she wants.

So η αδερφή μου θέλει σολομό... literally means:

• my sister wants salmon...

Depending on context, this can sound like:

• my sister wants salmon for lunch
• my sister would like salmon for lunch

Greek often uses θέλω in everyday speech where English might say want or would like.

Because σολομό is the accusative singular form, used for the direct object.

The dictionary form is:

• ο σολομός = the salmon

But after θέλει (wants), the noun is the object:

• θέλει σολομό = she wants salmon

So:

• nominative: ο σολομός
• accusative: τον σολομό / σολομό

This is a normal masculine noun pattern in Greek.

Greek often leaves out the article with food when speaking in a general way:

• με ψωμί = with bread

This sounds natural when you mean bread in general, not a specific loaf or piece.

If you wanted to refer to specific bread, you could use the article:

• με το ψωμί = with the bread

So the version in the sentence is natural and general.

Greek often uses the definite article in time expressions:

• το πρωί = in the morning
• το μεσημέρι = at noon / at lunchtime / in the middle of the day
• το βράδυ = in the evening

So το μεσημέρι is a standard time phrase.
In this sentence, it means something like at lunchtime or at noon.

Yes. Greek word order is more flexible than English, although the original sentence is very natural.

For example, these are possible:

• Για πρωινό τρώω βρώμη με λίγο μέλι...
• Τρώω βρώμη με λίγο μέλι για πρωινό...

The difference is usually about emphasis, not basic meaning.

The original version puts emphasis on the meal first:

• As for breakfast, I eat...

Both exist.

• αδερφή is very common in everyday modern Greek
• αδελφή is also correct and is a bit more formal/traditional

So a learner may see both. In normal conversation, αδερφή is extremely common.
