Hétfőn korán reggelizek, szombaton pedig később.

Because Hungarian usually does not use a separate preposition here. Instead, it adds a suffix to the day name.

So:

• hétfőn = on Monday
• szombaton = on Saturday

This is very common with days of the week in Hungarian.

They are both day-of-the-week forms, but the exact ending changes depending on the shape and sound of the word.

For example:

• hétfő → hétfőn
• szombat → szombaton

This is partly regular and partly something learners usually memorize as fixed forms. The weekday forms are:

• hétfőn = on Monday
• kedden = on Tuesday
• szerdán = on Wednesday
• csütörtökön = on Thursday
• pénteken = on Friday
• szombaton = on Saturday
• vasárnap = on Sunday

So the important thing is: Hungarian expresses on Monday / on Saturday by changing the day word itself.

Reggelizek means I have breakfast or I eat breakfast.

It comes from the verb reggelizni = to have breakfast.

The ending -ek shows 1st person singular present tense, so:

• reggelizek = I have breakfast

English does not usually say I breakfast, but Hungarian can express it with a single verb.

Because Hungarian verb endings usually already show the subject.

In reggelizek, the ending tells you the subject is I, so én is not necessary.

• (én) reggelizek = I have breakfast

Hungarian often leaves out subject pronouns unless they are needed for emphasis or contrast.

Here pedig is a contrastive connector. It means something like:

• whereas
• while
• on the other hand
• sometimes but

So the sentence contrasts two situations:

• Hétfőn korán reggelizek = On Monday I have breakfast early
• szombaton pedig később = but/on the other hand on Saturday later

In this sentence, pedig is not a strong contradiction like but in every context. It is more of a calm comparison or contrast.

Because Hungarian often leaves out repeated words when the meaning is obvious.

The full version would be:

Hétfőn korán reggelizek, szombaton pedig később reggelizek.

But that sounds more repetitive. Since the verb is already clear from the first clause, Hungarian naturally omits it in the second one.

So the original sentence really means:

On Monday I have breakfast early, and on Saturday I have breakfast later.

Because később means later, while későn means late.

• korán = early
• későn = late
• később = later

In this sentence, the idea is comparative: on Saturday, breakfast happens later than on Monday.

The ending -bb is the usual comparative ending in Hungarian, and it can be used with adverbs too.

Because pedig often comes after the element being contrasted.

Here the contrast is:

• hétfőn ... = on Monday ...
• szombaton pedig ... = on Saturday, on the other hand ...

This pattern is very common:

• X ..., Y pedig ...

So szombaton pedig sounds very natural.

You may see other word orders in Hungarian, but this one is the standard, clear pattern for this kind of contrast.

Not completely. Hungarian word order is flexible, but it is guided by emphasis and information structure.

The given order is natural and neutral:

• Hétfőn = topic/time frame
• korán = early
• reggelizek = I have breakfast

If you move words around, the sentence may still be grammatical, but the emphasis changes. For a learner, the original order is a very good model to follow.

Most naturally, it sounds like a routine or habit:

• On Mondays I have breakfast early, but on Saturdays later.

Hungarian present tense often expresses habitual actions like English simple present.

Without more context, a native speaker would usually understand this as something the speaker generally does, not just a one-time event.
