A fék most sajnos hibás.

A is the definite article in Hungarian, meaning the.

So:

• a fék = the brake

Hungarian has two forms of the:

• a before most consonant sounds
• az before vowel sounds

Since fék starts with f, it takes a: a fék.

Fék means brake.

In this sentence, a fék most naturally means the brake as a general machine part or vehicle part. Depending on context, English might say:

• the brake
• the brakes in natural English, if talking about a car system

But grammatically, Hungarian here is singular: fék = brake.

In Hungarian, the verb to be is often left out in the present tense, third person.

So where English says:

• The brake is faulty

Hungarian simply says:

• A fék hibás

No van is needed here.

This happens with sentences like:

• A ház nagy. = The house is big.
• A fiú fáradt. = The boy is tired.

But in other persons, the verb does appear:

• Én fáradt vagyok. = I am tired.
• Te fáradt vagy. = You are tired.

Most means now.

So it tells us that the brake is faulty at the moment / currently.

In this sentence:

• A fék most sajnos hibás.
• literally: The brake now unfortunately faulty.
• natural English: The brake is unfortunately faulty now.

Sajnos means unfortunately.

It is commonly used as a sentence adverb/comment word, expressing the speaker’s attitude toward the situation.

Examples:

• Sajnos késő van. = Unfortunately, it is late.
• Sajnos nem tudok menni. = Unfortunately, I can’t go.

Here it adds a tone of regret:

• A fék most sajnos hibás. = The brake is unfortunately faulty now.

Hibás means faulty, defective, or having a fault.

It is similar to rossz (bad) but more specific.

• hibás = something has a defect, malfunction, or error
• rossz = bad, poor, wrong, unpleasant, not good

For a mechanical part, hibás is often very natural because it suggests an actual fault.

Compare:

• A fék hibás. = The brake is faulty / defective.
• A fék rossz. = The brake is bad / not working properly.

Both can work, but hibás sounds more precise and technical.

Yes, Hungarian word order is flexible, but different orders change the focus or emphasis.

In:

• A fék most sajnos hibás.

the sentence feels fairly neutral: The brake is unfortunately faulty now.

You could also hear:

• A fék sajnos most hibás.
• Most a fék sajnos hibás.
• Sajnos a fék most hibás.

These all mean roughly the same thing, but the emphasis shifts slightly:

• most earlier = stronger focus on now
• sajnos earlier = stronger focus on unfortunately
• starting with A fék keeps the brake as the topic

Hungarian often arranges words according to information structure, not just fixed English-style order.

Here hibás is an adjective meaning faulty.

It acts as the predicate of the sentence:

• A fék ... hibás.
• The brake ... faulty.

Because Hungarian omits is in this kind of sentence, the adjective stands directly after the subject and any adverbs.

You can also use hibás before a noun:

• hibás fék = faulty brake
• hibás alkatrész = faulty component

A simple approximate pronunciation for an English speaker is:

• a fayk mosht SHOY-nosh HEE-baash

A few helpful details:

• é is a long ay sound, so fék sounds roughly like fayk
• s in Hungarian is like English sh
• sz would be English s, but there is no sz in this sentence
• j is like English y
• á is a long open vowel, roughly aa

So:

• sajnos ≈ shoy-nosh
• hibás ≈ hee-baash

The accent marks show different vowel sounds, not optional stress marks like in some languages.

For example:

• e and é are different vowels
• a and á are different vowels

So:

• fek and fék would not be the same word
• hibas would not be correct spelling for hibás

In Hungarian, these accents are a normal and important part of spelling.

Yes, depending on context, that may be the most natural English translation.

Hungarian says:

• A fék = literally the brake

But in English, when talking about a vehicle’s braking system, people often naturally say:

• The brakes are faulty.

So the Hungarian singular may correspond to either:

• The brake is faulty now
• The brakes are faulty now

The exact best translation depends on the real-world situation.

Yes.

• A fék most hibás. = The brake is faulty now.

Adding sajnos just adds the speaker’s attitude:

• A fék most sajnos hibás. = The brake is unfortunately faulty now.

So sajnos is not grammatically necessary; it adds emotional/pragmatic meaning.

A very literal breakdown is:

• A = the
• fék = brake
• most = now
• sajnos = unfortunately
• hibás = faulty

So the literal structure is:

• The brake now unfortunately faulty.

Natural English needs is, so a normal translation would be:

• The brake is unfortunately faulty now.
• or Unfortunately, the brake is faulty now.
