Előre lépünk.

Here előre is an adverb meaning forward or ahead.

It is often used with verbs of movement:

• menni előre = to go forward
• lépni előre = to step forward

In other contexts, előre can also mean in advance, so its exact meaning depends on the sentence.

Lépünk is the verb lépni in the 1st person plural present tense:

• lépni = to step
• lépünk = we step / we are stepping

So the ending shows that the subject is we.

Hungarian usually does not need a subject pronoun when the verb ending already makes the subject clear.

So:

• lépünk already means we step
• mi lépünk also means we step, but mi is only added for emphasis or contrast

For example:

• Mi lépünk, nem ők. = We are stepping, not them.

The ending -ünk marks 1st person plural: we.

Hungarian endings change according to vowel harmony. A very simple way to think about it is:

• verbs with back vowels often take -unk
• verbs with front vowels often take -ünk

Since lép has a front vowel (é), the form is lépünk.

Compare:

• várunk = we wait
• lépünk = we step

Yes, you may also see előrelépünk as one word, but there is an important difference in feel.

• előre lépünk = literally we step forward
• előrelépünk = a more fixed verb, often meaning we move ahead, we make progress, or sometimes we get promoted, depending on context

So the two-word version is very natural for actual physical movement, while the one-word version is often more lexicalized or figurative. In real usage, there can be some overlap, but this is a good basic distinction for learners.

Yes. Hungarian word order is flexible, and changing the order often changes the emphasis.

• Előre lépünk. puts strong attention on forward
• Lépünk előre. can sound a bit more neutral or descriptive

The exact nuance depends on context and intonation, but both are possible.

It can be either, depending on context.

Literal:

• taking an actual step forward

Figurative:

• making progress
• moving ahead in some plan or process

However, the separate version előre lépünk often sounds more literal, while előrelépünk as one word is especially common in figurative uses.

A rough pronunciation guide is:

• Előre ≈ EH-løø-reh
• lépünk ≈ LAY-pyünk

More accurately in IPA:

• előre = [ˈɛløːrɛ]
• lépünk = [ˈleːpyŋk]

A few important points:

• Hungarian stress is normally on the first syllable
• é is a long vowel
• ő is a long rounded front vowel, similar to German ö
• ü is a rounded front vowel, similar to German ü

So the accent marks do not show stress here; they mainly show vowel quality and/or length.

It can mean either one.

Hungarian present tense often covers both:

• simple present: we step
• present progressive: we are stepping

Usually the context tells you which one is meant. Hungarian does not need a separate verb form like English are stepping in order to express an ongoing action.
