Ez az alkatrész nagyon drága.

In Hungarian, the verb to be is usually left out in the present tense, third person when the predicate is a noun, adjective, or similar expression.

So:

• Ez az alkatrész nagyon drága. = This component is very expensive.

There is no van here, even though English needs is.

Compare:

• Én fáradt vagyok. = I am tired.
• Te fáradt vagy. = You are tired.
• Ő fáradt. = He/She is tired.
  → no separate word for is

So in this sentence, the is is understood.

This is one of the most common questions learners have.

In Ez az alkatrész, the words do not mean this that component.

What is happening is:

• ez = this
• az = the here, not that

Hungarian often uses a demonstrative + definite article + noun pattern:

• ez a könyv = this book
• ez az alkatrész = this component

The article changes form depending on the next word:

• a before a consonant
• az before a vowel

Because alkatrész starts with a vowel, you get:

• ez az alkatrész

So the structure is basically:

• ez + az + alkatrész = this + the + component

That is normal Hungarian grammar.

Hungarian has two forms of the definite article:

• a before a consonant
• az before a vowel

Since alkatrész begins with the vowel a, the correct form is:

• az alkatrész

More examples:

• a ház = the house
• a könyv = the book
• az autó = the car
• az ember = the person

So az is chosen purely because of pronunciation and sound flow.

Alkatrész usually means component, part, or spare part, depending on context.

It is especially common for:

• machine parts
• car parts
• electronic components
• mechanical components

So this sentence could mean things like:

• This component is very expensive.
• This part is very expensive.
• This spare part is very expensive.

The best English translation depends on the situation.

Nagyon means very.

It strengthens the adjective drága:

• drága = expensive
• nagyon drága = very expensive

This is similar to English word order:

• very expensive
• nagyon drága

So the sentence breaks down as:

• Ez az alkatrész = This component
• nagyon drága = very expensive

Because Hungarian, like English, normally puts the degree word before the adjective:

• nagyon drága = very expensive
• nagyon jó = very good
• nagyon kicsi = very small

So this part of the sentence follows a very familiar pattern for English speakers.

Yes. Drága can mean:

• expensive
• dear in an emotional sense, depending on context

Examples:

• Ez drága. = This is expensive.
• drágám = my dear / darling

In your sentence, because it is talking about an alkatrész (a component/part), the meaning is clearly expensive, not affectionate.

The neutral word order here is:

• Ez az alkatrész nagyon drága.
• literally: This component very expensive.

A useful way to see it is:

• subject/topic: Ez az alkatrész
• comment/predicate: nagyon drága

So the sentence presents the item first, then says something about it.

This is a very natural, neutral Hungarian sentence.

Yes, but the meaning changes slightly.

• Ez az alkatrész nagyon drága. = This component is very expensive.
• Az alkatrész nagyon drága. = The component is very expensive.

So if you want to point out this specific one, you need ez.

Without ez, you just have the component.

Yes.

• Ez az alkatrész drága. = This component is expensive.
• Ez az alkatrész nagyon drága. = This component is very expensive.

So nagyon just adds stronger emphasis.

A rough pronunciation guide for an English speaker is:

• Ez ≈ ez
• az ≈ awz or uz depending on accent, but short
• alkatrész ≈ AHL-kaw-trayss
• nagyon ≈ NAW-dyohn or NOH-dyon roughly
• drága ≈ DRAA-gaw

A few important pronunciation notes:

• Hungarian stress is usually on the first syllable of each word.
• sz is pronounced like English s.
• s by itself would sound like English sh.
• gy is a soft consonant, somewhat like the dy sound in duke in some pronunciations.
• á is a long vowel.

So:

• alkatrész has sz = s
• drága has long á
• nagyon contains the soft gy

It is simply a normal feature of Hungarian grammar.

When a demonstrative directly modifies a noun, Hungarian usually uses this pattern:

• ez a/az + noun = this + noun
• az a/az + noun = that + noun

Examples:

• ez a ház = this house
• ez az autó = this car
• az a könyv = that book

English does not use an article after this/that, but Hungarian usually does. So although it feels strange at first, it is standard and very common.

Ez is the basic form meaning this, yes, but its exact form can change in other grammatical contexts.

For example, Hungarian adds endings to demonstratives too:

• ez = this
• ezt = this as an object
• ebben = in this
• erről = about this

But in your sentence, ez is the basic dictionary form, because it is part of the phrase ez az alkatrész = this component.

Yes. Hungarian word order is flexible, and changing it can shift emphasis.

The neutral sentence is:

• Ez az alkatrész nagyon drága.

If you move things around, you may highlight a different part of the message. For example, a speaker might emphasize that it is very expensive, or that it is this component specifically.

However, for a learner, the original version is the best neutral model to remember.

Yes, absolutely.

For English speakers, it may look incomplete because English requires is:

• This component is very expensive.

But in Hungarian, this is a fully complete and correct sentence:

• Ez az alkatrész nagyon drága.

The missing is is not a mistake; it is just how Hungarian works in this kind of present-tense statement.
