A kávégép jól működik.

A is the Hungarian definite article, meaning the.

So A kávégép means the coffee machine.

Hungarian has two forms of the definite article:

• a
• az

Which one is used depends on the sound that follows.
You use a before a word beginning with a consonant, and az before a word beginning with a vowel.

Examples:

• a kávégép = the coffee machine
• az autó = the car

Hungarian often forms compound nouns by joining words together into one word.

Here:

• kávé = coffee
• gép = machine

So:

• kávégép = coffee machine

This is very common in Hungarian. English often writes such expressions as two words, but Hungarian frequently combines them into a single word.

This is a very common question.

• jó = good
• jól = well

In this sentence, jól is an adverb, because it describes how the machine works.

So:

• A kávégép jó. = The coffee machine is good.
• A kávégép jól működik. = The coffee machine works well.

A useful pattern:

• adjective: jó
• adverb: jól

English does something similar with good vs well.

Because működik means works / functions, and a verb is usually modified by an adverb, not an adjective.

So Hungarian uses:

• jól működik = works well

not

• jó működik ❌

This is the same logic as in English:

• It works well ✅
• It works good is nonstandard in careful English.

Működik means works, functions, or operates.

It is used for things like:

• machines
• devices
• systems
• methods
• plans

Examples:

• A számítógép működik. = The computer works.
• Ez a módszer jól működik. = This method works well.

So in your sentence, it means the coffee machine is functioning properly.

Működik is the 3rd person singular present tense form of the verb működni (to work / to function).

So:

• működni = to work, to function
• működik = it works / he works / she works

In this sentence, the subject is A kávégép, so in natural English it becomes:

• The coffee machine works well.

Hungarian often does not need a separate word for it because the verb ending already shows the person and number.

Hungarian word order is flexible, but it is not random. It often depends on focus and information structure rather than following a fixed English-style pattern.

In A kávégép jól működik, the order is very natural and neutral:

• A kávégép = topic / what we are talking about
• jól = well
• működik = works

So the whole sentence feels like: As for the coffee machine, it works well.

Hungarian very often places the verb later than English does, especially in simple neutral statements like this one.

Yes, but changing the order can change the emphasis.

The neutral version is:

• A kávégép jól működik.

You may also hear:

• Jól működik a kávégép.

This can sound a bit more like:

• The coffee machine works well, with attention on the fact that it works well
• or it may fit better in a certain context

In Hungarian, word order often reflects what is already known and what is being emphasized.

A few pronunciation tips:

• á is a long a sound
• é is a long e-like sound
• ű is a long front rounded vowel, a sound English does not have
• ö is also a rounded front vowel, somewhat similar to German ö

Roughly:

• kávégép ≈ kaa-vay-gayp
• működik ≈ something like muu-kö-dik, but with rounded lips on ű and ö

Also remember:

• Hungarian stress usually falls on the first syllable of the word.
• So: KÁ-vé-gép, MŰ-kö-dik

In Hungarian, accent marks are not optional decoration. They show different vowels, and vowel length matters.

For example:

• a and á are different vowels
• e and é are different vowels
• u and ú, ü and ű, o and ó, ö and ő are also different

So in:

• kávégép
• jól
• működik

the marks are part of the correct spelling and pronunciation.

If you leave them out, the word may become incorrect or even turn into a different word.

Usually, if you mean the coffee machine, you would keep the article:

• A kávégép jól működik.

Without the article:

• Kávégép jól működik.

this would generally sound incomplete or unnatural in a normal sentence.

Hungarian often uses articles in places where English does too, though not always in exactly the same way. In this sentence, the definite article is the normal choice.
