A gomb kicsi.

Here a is the definite article, so it means the.

• a gomb = the button
• Hungarian also has an indefinite article, egy, which means a/an

So:

• A gomb kicsi. = The button is small.
• Egy gomb kicsi. = A button is small. / One button is small. depending on context

Hungarian has two forms of the definite article:

• a before a consonant
• az before a vowel

Since gomb starts with g, a consonant, you say a gomb.

Examples:

• a ház = the house
• az alma = the apple

In Hungarian, the verb to be is often left out in the present tense, third person singular/plural when the sentence links a noun or pronoun to an adjective or another noun.

So:

• A gomb kicsi. literally looks like The button small.
• But it means The button is small.

This is normal Hungarian grammar.

Compare:

• Én kicsi vagyok. = I am small.
• Te kicsi vagy. = You are small.
• A gomb kicsi. = The button is small.

In the third person present, van is usually not used here.

Because in this sentence kicsi is part of the predicate: it tells you something about the button.

So:

• A gomb kicsi. = The button is small.

But if you want to say the small button, the adjective normally goes before the noun:

• a kicsi gomb = the small button

This is an important difference:

• A gomb kicsi. = a full sentence
• A kicsi gomb = just a noun phrase

Not completely. A gomb kicsi is a natural, neutral way to say it, but Hungarian word order can change for emphasis.

For example:

• A gomb kicsi. = neutral: The button is small.
• Kicsi a gomb. = emphasis on small; something like The button is small / It’s the button that’s small

The basic meaning stays similar, but the focus changes.

This is a very common learner question.

Both kicsi and kis relate to small/little, but they are used differently:

• kicsi can stand on its own as the adjective in a sentence:
  • A gomb kicsi.
• kis is usually used directly before a noun:
  • egy kis gomb = a small button

So:

• A gomb kicsi. is correct.
• A gomb kis. is not the normal form here.

A simple rule for beginners:

• before a noun: often kis
• after the noun / as the main adjective in the sentence: kicsi

No. Hungarian does not have grammatical gender like he/she/it systems in many Indo-European languages, and adjectives do not agree the way they do in languages like French, German, or Spanish.

So kicsi stays kicsi.

Examples:

• A gomb kicsi. = The button is small.
• A gombok kicsik. = The buttons are small.

Notice that in the plural sentence, the adjective can take a plural form when it is used predicatively: kicsik.

But there is still no gender agreement.

A rough pronunciation guide:

• a = a short sound like the o in British hot for many speakers
• gomb = roughly gom(b), with a clear g
• kicsi = roughly KI-chi

A more detailed approximation:

• A → aw/oh-like short vowel
• gomb → gomb
• kicsi → kit-chi or kee-chi as a rough learner approximation

Useful pronunciation notes:

• Hungarian stress normally falls on the first syllable of each word.
• cs is pronounced like ch in church.

So kicsi sounds like KI-chi.

Yes, depending on context, gomb can mean:

• button on clothes
• button on a device
• sometimes knob

So the exact English translation depends on the situation.

Also, learners sometimes confuse gomb with gomba:

• gomb = button
• gomba = mushroom

They are different words.

Not with a. In standard Hungarian, a is definite, so A gomb kicsi means The button is small.

If you want a button, you normally use egy:

• Egy gomb kicsi.

That said, in real translation, English sometimes uses the or a differently depending on context, but grammatically the Hungarian article here is definite.

Yes, absolutely.

Even though there is no visible word for is, A gomb kicsi. is a full, correct Hungarian sentence.

Its structure is perfectly normal:

• A gomb = subject
• kicsi = predicate adjective

So for Hungarian, nothing is missing.
