Addig keresi a bérletét, amíg meg nem találja.

This is a very common Hungarian time-expression pattern.

• addig = until then / for that long / up to that point
• amíg = until / as long as / while

Together, addig ... amíg means something like for as long as ... until .... In this sentence, it sets up a limit:

• Addig keresi ... = He/She keeps looking ...
• amíg meg nem találja = until he/she finds it

Hungarian often likes this kind of paired structure, where the main clause has one word and the subordinate clause answers or completes it.

Because in Hungarian, after amíg with the meaning until, nem is very often used even when the overall meaning is positive.

So:

• amíg meg nem találja means until he/she finds it
• not until he/she does not find it

This is a pattern you should learn as a whole. English does not do this, so it feels strange at first.

Similar examples:

• Vár, amíg meg nem jön. = He waits until she arrives.
• Olvas, amíg el nem alszik. = He reads until he falls asleep.

So here nem is part of the until construction, not ordinary negation.

That is a very useful question, because the two patterns are different.

1. Ordinary negation

With a prefixed verb, normal negation usually looks like this:

• nem találja meg = he/she does not find it

Here the prefix meg moves after the verb.

2. The amíg ... nem / until pattern

In this sentence, nem is not ordinary negation. It belongs to the fixed until construction:

• amíg meg nem találja = until he/she finds it

That is why the prefix stays before nem.

So:

• nem találja meg = genuinely negative
• meg nem találja after amíg = the usual until structure

The prefix meg- often gives a sense of completion, success, or reaching a result.

Compare:

• talál = find, come across
• megtalál = find successfully, locate

In this sentence, that matters because the first verb is about an ongoing process:

• keresi = is looking for it / keeps searching for it

And the second verb marks the endpoint of that process:

• megtalálja = finds it

So the sentence contrasts:

• ongoing search
• completed result

Because both verbs use the definite conjugation.

Hungarian has two conjugation patterns:

• indefinite conjugation: used when there is no definite object
• definite conjugation: used when the object is definite

Here the object is definite:

• a bérletét = his/her pass

So Hungarian uses:

• keresi rather than keres
• találja rather than talál

Even in the second clause, the object is not repeated, but it is understood from context: it, meaning the pass. Since that understood object is definite, találja is still definite conjugation.

bérletét can be broken down like this:

• bérlet = pass / ticket / travel pass
• bérlete = his/her pass
• bérletét = his/her pass as a direct object

So the ending shows two things at once:

1. possession: it belongs to him/her
2. accusative: it is the object of the verb

A simple way to think of it is:

• bérlet = pass
• bérlete = his/her pass
• bérletét = his/her pass + object ending

Because Hungarian often uses the definite article a/az even with possessed nouns.

So:

• a bérletét literally has the structure the his/her pass
• but that is completely normal in Hungarian

English usually says just his/her pass, without the. Hungarian often does not work that way.

Other similar examples:

• keresi a kulcsát = he is looking for his key
• eladta az autóját = he sold his car
• felvette a kabátját = she put on her coat

So the article here is not extra or wrong; it is standard Hungarian usage.

Because Hungarian often leaves pronouns out when they are clear from the verb form or the context.

Subject

The verb endings already show third person singular:

• keresi
• találja

So Hungarian does not need ő unless you want emphasis or contrast.

Object

In the second clause, English needs finds it, but Hungarian can simply say találja, because the object is already understood from the first clause:

• a bérletét → that is what is being found

So Hungarian is often more comfortable than English with leaving pronouns unspoken.

Both verbs are in the present tense, but the sentence can still have different kinds of meaning depending on context.

Most naturally, it sounds like:

• a general statement
• a habitual pattern
• a typical action
• or a vivid present-style description

So it can mean something like:

• He keeps looking for his pass until he finds it.

If you wanted a clearly past version, you would say:

• Addig kereste a bérletét, amíg meg nem találta.

So the present tense here does not have to mean right now at this exact second. Hungarian present tense is often used more broadly than English learners first expect.

Yes, Hungarian word order is flexible, but different orders give different emphasis.

The given sentence is a very natural, neutral version:

• Addig keresi a bérletét, amíg meg nem találja.

If you move something to the front, you usually highlight it.

For example:

• A bérletét keresi addig, amíg meg nem találja.

This puts more attention on the pass.

So Hungarian word order is not random. It is shaped by:

• topic
• emphasis
• contrast
• what is already known in the conversation

The original order is a good standard version to learn first.

Yes, very much.

This sentence is built around two different kinds of action:

• keresi = an ongoing activity
• megtalálja = reaching the result

That is why the sentence feels so natural:

• first there is the process of searching
• then there is the endpoint of finally finding it

Hungarian often expresses this kind of contrast very clearly with:

• an unprefixed verb for the ongoing action
• a prefixed verb for the completed result

So the sentence is not just about two actions. It is about continuing an action up to its successful completion.
