A keresztény ehhez a közösséghez tartozik.

A is the Hungarian definite article, usually equivalent to the.

Hungarian has two forms of the definite article:

• a before a consonant sound
• az before a vowel sound

So:

• a keresztény = the Christian
• az ember = the person

In this sentence, a is used because keresztény begins with a consonant sound.

Also, in general statements, Hungarian often uses the definite article where English may use the, a, or even no article, depending on how the sentence is translated.

Here it is a noun: Christian.

Hungarian words like keresztény can often be used both ways:

• keresztény közösség = Christian community → adjective
• a keresztény = the Christian / a Christian → noun

So in your sentence, keresztény is not describing another noun. It stands on its own and means a Christian person.

It can be generic.

Hungarian often uses a singular noun with the definite article to talk about a whole type or class. So a keresztény can mean:

• the Christian in a general sense
• sometimes more naturally in English, a Christian
• or even Christians, depending on the wider context

So the singular form does not automatically mean one specific individual.

If Hungarian wanted to stress one unspecified Christian, it would more likely use egy keresztény.

Because ez and az have irregular case forms.

When case endings are added, ez and az often change shape instead of simply taking the suffix directly. So:

• ez → ehhez = to this
• az → ahhoz = to that
• ebben = in this
• abban = in that
• erről = about this / from this
• arról = about that / from that

So ehhez is just the correct case form of ez.

Literally, it means to this community.

Breaking it down:

• ehhez = to this
• a = the
• közösséghez = to community / to the community

So the whole phrase is the normal Hungarian way to say to this community.

With the verb tartozik, this phrase is understood idiomatically as belongs to this community.

Because in Hungarian, the demonstrative and the noun usually both show the same case.

This is a very common pattern:

• ebben a házban = in this house
• ehhez a közösséghez = to this community
• azzal a tanárral = with that teacher

So Hungarian does not usually say just the equivalent of this community-to. It marks both parts:

• ehhez = to this
• közösséghez = to community

That double marking is normal and important.

Because the article goes with the noun, not with the demonstrative.

The noun is közösséghez, which begins with k, a consonant sound, so Hungarian uses a:

• ehhez a közösséghez

Even though ehhez begins with a vowel sound, that does not control the article. The article is chosen according to the following noun.

Compare:

• ebben a házban = in this house
• ebben az épületben = in this building

Here the second one uses az because épületben starts with a vowel sound.

-hez is an allative ending. It often means to or toward.

Examples:

• a házhoz = to the house
• az asztalhoz = to the table
• ehhez = to this

In your sentence, though, it is not about physical movement. With tartozik, Hungarian uses this ending to express belonging to a group, category, or institution.

So:

• ehhez a közösséghez tartozik = belongs to this community

Hungarian chooses among -hoz / -hez / -höz according to vowel harmony and the sound pattern of the word.

Very roughly:

• -hoz after back-vowel words
• -hez after front unrounded patterns
• -höz after front rounded patterns

In közösséghez, the final vowel pattern leads to -hez, so the correct form is:

• közösséghez

This is something learners usually need to get used to word by word, although vowel harmony rules help a lot.

Here tartozik means belongs.

A very common pattern is:

• tartozik valamihez / valakihez = to belong to something / someone

So:

• ehhez a közösséghez tartozik = belongs to this community

Be careful: tartozik can also mean owes, in a different structure. For example:

• Péter pénzzel tartozik = Peter owes money

So the meaning depends on the construction. In your sentence, with -hoz / -hez / -höz, it means belong to.

It is the third person singular present tense form:

• ő tartozik = he/she belongs
• or simply belongs

Hungarian usually leaves out subject pronouns when they are not needed, so there is no separate word for he/she here.

The dictionary form is also tartozik.

A few related forms are:

• tartozom = I belong / I owe
• tartozol = you belong / you owe
• tartozik = he/she belongs / owes
• tartozunk = we belong / owe

Hungarian word order is fairly flexible, but it is not random. It depends a lot on topic, focus, and emphasis.

The sentence

• A keresztény ehhez a közösséghez tartozik.

is a natural, neutral order:

• A keresztény = topic / what we are talking about
• ehhez a közösséghez = complement
• tartozik = verb

If you changed the order, you could change the emphasis. For example, putting ehhez a közösséghez in a more prominent position could stress this community in contrast to some other group.

So the given order is normal and natural, but not the only possible one.

A rough pronunciation guide:

• A = short aw
• keresztény = roughly KEH-res-tayny
• ehhez = roughly EH-hez
• közösséghez = roughly KUH-zuh-shayg-hez, but with Hungarian ö sounds
• tartozik = TAR-to-zik

A few useful spelling points:

• sz sounds like English s
• s sounds like English sh
• é is a long ay
• ö is a front rounded vowel, like German ö or French eu
• ny sounds like Spanish ñ in niño

Also, Hungarian normally stresses the first syllable of each word:

• A KER-esztény EH-hez a KÖ-zös-ség-hez TAR-to-zik
