Kérem, mondja meg pontosan a címet, különben nem találom meg a házat.

Yes, in this kind of sentence kérem works like please.

Literally, kérem comes from the verb kér = to ask/request, so kérem originally means I ask or I request. But in everyday polite Hungarian, it is very often used just as a polite marker, like please in English.

So here:

• Kérem = Please
• Kérem, mondja meg... = Please tell me...

It is a formal, polite way of speaking.

Because mondja is the formal command form.

Hungarian has different ways to give commands depending on who you are speaking to:

• mondd = tell when speaking informally to one person
• mondja = tell when speaking formally to one person, using Ön

So this sentence is addressing someone politely/formally:

• Kérem, mondja meg... = Please tell me...

If you were talking to a friend, you would more likely say:

• Mondd meg pontosan a címet...

Here meg is a verbal prefix. It often gives the verb a sense of completion or result.

Compare:

• mond = say, tell
• megmond = tell, state, let someone know clearly/completely

So mondja meg is not just say in a vague sense; it is more like:

• tell me
• say it clearly
• give me the information

In many cases, English does not translate meg as a separate word. It is just part of how Hungarian expresses a completed action.

Because a címet is in the accusative case, which marks the direct object.

• cím = address
• a cím = the address
• a címet = the address as the thing being told/specified

In this sentence, the speaker wants the other person to tell the address, so address is the direct object.

That is why it gets -t:

• Kérem, mondja meg a címet. = Please tell me the address.

Yes, but the meaning is slightly different.

In the sentence:

• mondja meg pontosan a címet

pontosan is an adverb, and it means accurately / exactly / precisely. It modifies the action of telling:

• tell me the address accurately/exactly

If you say:

• a pontos címet

then pontos is an adjective modifying cím, so it means:

• the exact/accurate address

Both are possible, but they focus slightly differently:

• mondja meg pontosan a címet = tell me the address precisely
• mondja meg a pontos címet = tell me the exact address

In practice, both can sound natural depending on context.

Because Hungarian often leaves out pronouns when they are understood from context.

In English, you say:

• Please tell me the address

In Hungarian, the me does not have to be stated if it is obvious. So:

• Kérem, mondja meg a címet

already naturally means:

• Please tell me the address

If you want to make me explicit, you could say:

• Kérem, mondja meg nekem a címet.

Here nekem = to me.

Különben means otherwise.

It introduces the consequence if the request is not followed:

• Kérem, mondja meg pontosan a címet, különben nem találom meg a házat.
• Please tell me the address exactly, otherwise I won’t find the house.

It is a very common connector in Hungarian.

Because in Hungarian, verbal prefixes like meg often move after the verb when the verb is negated.

Positive:

• megtalálom = I find it / I will find it

Negative:

• nem találom meg = I do not find it / I won’t find it

This is a very important Hungarian pattern:

• megírom → nem írom meg
• megmondom → nem mondom meg
• megtalálom → nem találom meg

So the position of meg changes because of nem.

Yes. In both cases, meg is a verbal prefix that adds a sense of completion or successful result.

• megmond = tell, say clearly, let someone know
• megtalál = find, manage to find

In megtalál, the idea is not just look for, but actually find successfully.

So:

• nem találom meg a házat = I won’t be able to find the house

The core idea is that the action reaches its result.

Because Hungarian uses the definite conjugation here.

The object is:

• a házat = the house

Since the verb has a definite direct object, Hungarian normally uses the definite verb form:

• találok = I find something indefinite
• találom = I find it / I find the specific thing

So:

• találom a házat / megtalálom a házat = definite object
• találok egy házat = indefinite object

This is one of the central grammar features of Hungarian.

Because the speaker means a specific house.

• ház = house
• házat = a house as object
• a házat = the house as object

In the context, the address refers to a particular house, so Hungarian uses the definite article:

• nem találom meg a házat = I won’t find the house

If you said házat without a, it would sound more like a house in a general sense.

Yes, definitely.

The main clues are:

• kérem = polite please
• mondja = formal command form

So this is the kind of sentence you would use with:

• a stranger
• an official
• an older person
• someone you want to address politely

An informal version to one friend would be:

• Mondd meg pontosan a címet, különben nem találom meg a házat.

Yes. Hungarian present tense can often cover meanings that English expresses with will, can, or simple present, depending on context.

So:

• nem találom meg a házat

can be understood as:

• I won’t find the house
• I can’t find the house
• I won’t be able to find the house

In this sentence, because of különben and the overall logic, English usually translates it as something like:

• otherwise I won’t find the house
• otherwise I won’t be able to find the house

Because különben introduces a new clause, and Hungarian normally separates that kind of clause with a comma.

So the sentence has two parts:

1. Kérem, mondja meg pontosan a címet
2. különben nem találom meg a házat

That is why you see:

• ..., különben ...

There is also a comma after Kérem, because it is being used like a polite introductory expression: Please, ...
