Előre elmondom a szabályt.

Here előre means in advance, beforehand.

So Előre elmondom a szabályt is not about physically moving forward. In other contexts, előre can mean forward, but in this sentence it means that the speaker is saying the rule ahead of time.

No.

• előre is a separate adverb: beforehand / in advance
• el- is a verbal prefix attached to mond

So:

• mond = say
• elmond = tell / say / recite / explain (often with a sense of completing the act of saying)

Even though előre and el- look a little similar, they are doing different jobs.

The basic verb is mond = to say.

With the prefix, it becomes elmond = to tell / to say / to recite.

The infinitive is elmondani.

So elmondom can be broken down like this:

• el- = verbal prefix
• mond = verb stem
• -om = I form used with a definite object

Because Hungarian has two kinds of verb conjugation:

• indefinite conjugation
• definite conjugation

Here the object is a szabályt = the rule, which is definite/specific, so the verb uses the definite form:

• elmondom a szabályt = I tell the rule / I'll tell the rule

Compare:

• elmondok egy szabályt = I tell a rule
• elmondom a szabályt = I tell the rule

This is a very important pattern in Hungarian.

Because -t is the accusative ending, which marks the direct object.

The rule is what is being told, so Hungarian marks it:

• szabály = rule
• szabályt = rule as a direct object

And:

• a szabályt = the rule

So the -t here is not part of the dictionary form of the noun. It is a case ending.

Formally, elmondom is present tense.

But Hungarian often uses the present tense to talk about the future when the context makes that clear. In this sentence, előre already suggests something like beforehand / ahead of time, so a future interpretation is very natural.

So depending on context, Előre elmondom a szabályt can sound like:

• I’m telling the rule in advance
• I’ll tell you the rule beforehand

If you want a more explicitly future form, Hungarian can also say:

• El fogom mondani a szabályt.

But the original sentence is completely natural.

It is not stated.

Hungarian often leaves out things that are understood from context, especially pronouns. So this sentence does not explicitly say who the rule is being told to.

If needed, you could add it:

• Előre elmondom neked a szabályt. = I’ll tell you the rule beforehand.

Without neked, the listener is simply understood from the situation.

Hungarian word order is flexible, but it is not random. It often reflects emphasis and information structure.

In Előre elmondom a szabályt, the order is natural and straightforward:

• Előre = beforehand
• elmondom = I tell / I’ll tell
• a szabályt = the rule

This gives a neutral sense like I’ll say the rule in advance.

You can move things around, but that changes what is highlighted. For example:

• A szabályt előre elmondom.
  This puts more attention on the rule.

With stronger focus, Hungarian can also separate the verbal prefix:

• Előre mondom el a szabályt.

That is more advanced, but it shows that word order in Hungarian often expresses emphasis rather than strict grammatical roles.

Hungarian has two forms of the definite article:

• a before consonant sounds
• az before vowel sounds

Since szabály begins with a consonant sound (sz), the correct form is:

• a szabályt

If the next word began with a vowel, you would use az instead.

A few useful pronunciation points:

• sz is pronounced like English s
• ly in modern Hungarian is pronounced like j / y
• the word stress is on the first syllable

So szabály sounds roughly like SA-boy (very approximate), and szabályt adds a final t.

Also:

• ő in előre is a long vowel not found in standard English
• every written vowel length matters in Hungarian, so ö and ő are not the same

You do not need to pronounce it exactly like English spelling suggests; it is better to learn it as a Hungarian sound pattern.
