Különböző dalokat énekelnek.

Hungarian often leaves subject pronouns out because the verb ending already shows who the subject is.

Here, énekelnek tells you the subject is they because it is 3rd person plural.
So ők would usually be unnecessary unless you want extra emphasis, as in Ők énekelnek, meaning something like they are the ones singing.

In énekelnek, the ending -nek marks 3rd person plural in the present tense.

So:

• énekel = he/she sings
• énekelnek = they sing

This form is also part of the indefinite conjugation, which Hungarian uses when the object is not definite or specific.

Dalokat comes from dal, meaning song.

It has two things added:

• -ok = plural, so dalok = songs
• -at / -t = accusative, marking the direct object

So:

• dal = song
• dalok = songs
• dalokat = songs as the object of the verb

Since the songs are what they are singing, Hungarian marks that with the accusative.

Because in Hungarian, an adjective before a noun usually stays in its basic form. The noun carries the plural and case endings, not the adjective.

So you get:

• különböző dal = a different/various song
• különböző dalok = different/various songs
• különböző dalokat = different/various songs as object

This is different from languages where adjectives agree more fully with the noun.

Hungarian word order is much more flexible than English word order. It is not based mainly on a fixed subject–verb–object pattern. Instead, it often depends on topic, focus, and what sounds most natural in context.

In a neutral sentence, an indefinite object like különböző dalokat often appears directly before the verb:

• Különböző dalokat énekelnek.

That is a very natural Hungarian order.

You may also see other orders in other contexts, but the Hungarian sentence does not need to match English word order.

It can mean either one, depending on context.

Hungarian present tense often covers both:

• they sing
• they are singing

So without more context, énekelnek could describe a general habit or something happening right now.

In Hungarian, having an object is not enough by itself to trigger the definite conjugation. The object must also be definite / specific.

Here, különböző dalokat means different songs / various songs, which is not a specific, definite set. So Hungarian uses the indefinite verb form:

• énekelnek

Compare:

• Különböző dalokat énekelnek. = indefinite object
• A dalokat éneklik. = the songs are definite, so the verb is definite éneklik

Here, különböző functions as an adjective, describing dalokat.

It means something like:

• different
• various

In this sentence, it describes what kind of songs they sing.

It comes historically from a verb related to being different, but for a learner at this stage, it is best to treat it as a normal adjective.

A rough guide is:

kü-lön-bö-ző

A few important points:

• ü is a front rounded vowel, similar to German ü or French u
• ö is similar to German ö
• ő is the long version of ö
• stress in Hungarian normally falls on the first syllable, so: KÜ-lön-bö-ző

The vowel length matters: ö and ő are not the same sound length.

Yes. Hungarian present tense is often quite broad.

So this sentence could mean:

• something happening now
• something they do regularly
• a general fact about them

Only the context tells you which meaning is intended. That is completely normal in Hungarian.
