Vacsora előtt még egyszer megnézem a menetrendet, mert holnap korán indulunk.

Vacsora előtt means before dinner in a general sense. In Hungarian, meals and many time expressions often appear without the article when used like this.

• vacsora = dinner
• előtt = before

So:

• Vacsora előtt = before dinner
• Reggel = in the morning
• Ebéd után = after lunch

You can say a vacsora előtt, but that sounds more like before the dinner — referring to a specific dinner event rather than the general mealtime.

Előtt is a postposition, which means it comes after the word it belongs to, not before it as in English.

• vacsora előtt = before dinner
• ház előtt = in front of the house
• óra előtt = before one o’clock / before class, depending on context

English uses prepositions like before, in front of, after. Hungarian often uses postpositions instead:

• a ház előtt = in front of the house
  literally: the house in-front-of

Még egyszer means once more / one more time / again.

In this sentence:

• még = still, yet, more
• egyszer = once

Together, még egyszer megnézem means I’ll check/look at it once more.

This is a very common expression:

• Mondd még egyszer! = Say it again!
• Megnézem még egyszer. = I’ll look at it once more.

Nézni means to look at / to watch, while megnézni often means to look at something and check it / view it / have a look at it completely.

The prefix meg- often gives the verb a more completed or goal-oriented sense.

So:

• nézem a menetrendet = I’m looking at the timetable
• megnézem a menetrendet = I’ll check the timetable / I’ll have a look at the timetable

Here, megnézem is natural because the speaker means I’ll check it rather than just I’ll be looking at it.

Because Hungarian verbs conjugate differently depending on whether they have a definite object.

Here the object is:

• a menetrendet = the timetable

That is a definite object, so Hungarian uses the definite conjugation:

• megnézem = I check it / I will check it

Compare:

• Megnézek egy menetrendet. = I check a timetable.
  → indefinite object, so megnézek
• Megnézem a menetrendet. = I check the timetable.
  → definite object, so megnézem

This is one of the most important features of Hungarian grammar.

The -t marks the accusative case, which usually shows the direct object of the verb.

• menetrend = timetable, schedule
• a menetrend = the timetable
• a menetrendet = the timetable (as the direct object)

Since megnézem is doing something to the timetable, Hungarian marks it with -t.

More examples:

• Olvasom a könyvet. = I’m reading the book.
• Iszom a kávét. = I’m drinking the coffee.

Hungarian often inserts a linking vowel before case endings to make pronunciation easier.

So:

• menetrend + -t becomes menetrendet

This is very common. The exact form depends on the noun.

Compare:

• könyv → könyvet
• asztal → asztalt
• menetrend → menetrendet

You usually just learn these object forms as part of normal noun patterns.

Formally, it is present tense, but Hungarian very often uses the present tense to talk about the future when the time is clear from context.

Here the future meaning is obvious because of:

• Vacsora előtt = before dinner
• holnap = tomorrow

So megnézem means something like:

• I’ll check
• I’m going to check

Similarly:

• Holnap indulunk. = We leave tomorrow.
• Este telefonálok. = I’ll call in the evening.

Hungarian usually prefers the simple present for future events if there is a clear time expression.

So:

• holnap korán indulunk = we leave early tomorrow

This sounds more natural than holnap korán fogunk indulni in most everyday situations.

The fog + infinitive future exists, but it is often used when:

• the future meaning is not otherwise clear
• you want emphasis
• the action is less scheduled or less immediate

In this sentence, holnap already makes the future clear, so indulunk is the natural choice.

Indulunk comes from indulni, which means to leave, to set off, or to depart.

• indulok = I leave / I’m leaving
• indulsz = you leave
• indul = he/she leaves
• indulunk = we leave

In this sentence:

• holnap korán indulunk = we’re leaving early tomorrow / we set off early tomorrow

It suggests departure, especially the start of a trip or journey.

Korán is an adverb meaning early.

So:

• korán indulunk = we leave early

Compare:

• korai = early (adjective)
• korán = early (adverb)

Examples:

• korai vonat = an early train
• Korán kelek. = I get up early.

Hungarian word order is flexible, but it is strongly connected to topic, focus, and emphasis.

In this sentence:

• Vacsora előtt sets the time frame: before dinner
• még egyszer adds once more
• megnézem a menetrendet gives the main action

This order sounds natural because it moves from time to extra detail to action.

You could change the word order for emphasis. For example:

• A menetrendet nézem meg még egyszer vacsora előtt.
• Még egyszer megnézem vacsora előtt a menetrendet.

These are possible, but the original is the most neutral and natural everyday version.

Yes, Hungarian allows some movement, but the position can slightly change the emphasis.

Original:

• Vacsora előtt még egyszer megnézem a menetrendet.

This is neutral and natural.

Other possible versions:

• Még egyszer megnézem a menetrendet vacsora előtt.
• Vacsora előtt megnézem még egyszer a menetrendet.

These still mean basically the same thing, but the rhythm and emphasis shift a bit. Learners should usually stick with the original order unless they have a reason to stress something.

Mert means because.

It introduces the reason:

• Vacsora előtt még egyszer megnézem a menetrendet
  = I’ll check the timetable once more before dinner
• mert holnap korán indulunk
  = because we’re leaving early tomorrow

So the second clause explains why the speaker wants to check the timetable again.

Because Hungarian normally uses a comma before certain subordinate clauses, including clauses introduced by mert (because).

So:

• ..., mert ... = ..., because ...

This is standard Hungarian punctuation.

Yes. Menetrend can mean a timetable, schedule, or transport schedule, depending on context.

It is often used for:

• train schedules
• bus timetables
• departure schedules

In everyday speech, it often refers to transport timing, not just a general plan.

So here megnézem a menetrendet most naturally means:

• I’ll check the timetable/schedule

Yes — it combines several very common Hungarian patterns:

1. Postposition

   • vacsora előtt = before dinner

2. Present tense with future meaning

   • megnézem
   • indulunk

3. Verb prefix

   • megnézem vs nézem

4. Definite conjugation

   • megnézem because of a menetrendet

5. Accusative object

   • menetrendet

6. Natural time expression without article

   • vacsora előtt

So although the sentence is not long, it is very useful as a model for real Hungarian.
