A ruhapróbán ellenőrizzük a méretet.

Ruhapróbán means at the fitting or during the fitting.

It comes from the noun ruhapróba:

• ruha = clothing, dress
• próba = trial, fitting, try-on

Together, ruhapróba means clothing fitting or dress fitting.

The ending -n here is a location-related ending. With some time/event words, it can mean something like at or during:

• a ruhapróbán = at the fitting

So the sentence is talking about what happens during that event.

A is the Hungarian definite article, meaning the.

So:

• a ruhapróbán = at the fitting
• a méretet = the size

Hungarian uses a / az for the:

• a before most consonant sounds
• az before vowel sounds

Since ruhapróba starts with r, it takes a.

Ellenőrizzük means we check, we inspect, or we verify.

The base verb is:

• ellenőriz = to check, inspect, verify

In this sentence, it appears in 1st person plural:

• ellenőriz-zük = we check

So the sentence literally means:

• At the fitting, we check the size.

This is because Hungarian has definite and indefinite verb conjugation.

Here the object is:

• a méretet = the size

Because the object is definite (the size, not just a size), Hungarian uses the definite conjugation of the verb:

• ellenőrzünk = we check something indefinite / in general
• ellenőrizzük = we check it / we check the specific one

So:

• Méretet ellenőrzünk. = We check a size / sizes.
• A méretet ellenőrizzük. = We check the size.

Because it is the direct object of the verb.

In Hungarian, direct objects usually take the accusative ending -t. Sometimes an extra vowel appears before the -t for pronunciation.

So:

• méret = size
• méretet = size + accusative = the size as the thing being checked

This is very common:

• könyv → könyvet
• ruhát from ruha
• méret → méretet

Yes, in context this kind of we can sound more natural in Hungarian than in English.

Ellenőrizzük literally means we check, but in service, work, or procedure contexts, Hungarian often uses we where English might sometimes use:

• we check
• they check
• the size is checked
• one checks the size

For example, in a shop or tailoring context, we may refer to the staff in a natural, professional way.

So the Hungarian is literally we check the size, but depending on context the English translation could be adjusted.

Yes, you could say it differently, but the emphasis may change.

The given sentence:

• A ruhapróbán ellenőrizzük a méretet.

This is a neutral and natural way to say:

• At the fitting, we check the size.

Other possible orders:

• A méretet a ruhapróbán ellenőrizzük.
  This emphasizes the size more.
• Ellenőrizzük a méretet a ruhapróbán.
  Also possible, with a slightly different flow.

Hungarian word order is more flexible than English word order, but it often reflects focus, topic, and emphasis, not just grammar.

Yes. Hungarian very often forms compound nouns as one word.

Here:

• ruha = clothes, garment
• próba = trial, fitting

Together:

• ruhapróba = fitting, dress fitting, clothing try-on

This is very normal in Hungarian. English often uses multiple words where Hungarian prefers a compound.

Yes. Méret generally means size, but in some contexts it can also mean measurement or dimensions.

In this sentence, because it is about a fitting, a méretet most naturally means:

• the size
• possibly the fit/measurement depending on context

If the meaning has already been given to the learner, then the size is the intended reading here.

A rough pronunciation guide:

• ellenőrizzük ≈ el-leh-nuh-riz-zük, but this is only approximate

A few important points:

• Hungarian stress is almost always on the first syllable: EL-lenőrizzük
• ő is a long front rounded vowel, somewhat like a long version of the vowel in German schön or French deux
• ü is also a front rounded vowel, like German ü

If those sounds are unfamiliar, it is best to hear native audio, because English does not have exact equivalents.

Both endings can relate to location, but they do not mean exactly the same thing.

Here, a ruhapróbán means at the fitting / during the fitting, treating ruhapróba as an event or occasion.

If you used -ban/-ben, it would more literally mean in something, which sounds less natural for this event-based meaning.

So:

• a ruhapróbán = at/during the fitting ← natural here
• a ruhapróbában = would sound unusual in this context

For events, Hungarian often uses endings like the one in -n rather than the basic in ending.
