Egyrészt a fúrás zavaró, másrészt a kopogás is zavaró.

They are a common pair meaning on the one hand ... on the other hand ... or for one thing ... for another.

So:

• egyrészt = on the one hand / for one thing
• másrészt = on the other hand / for another thing

They are used to present two separate points, two sides of a situation, or two reasons.

It is not written, because Hungarian often leaves out the verb to be in the present tense when the predicate is an adjective or a noun.

So:

• a fúrás zavaró = the drilling is annoying
• literally: the drilling annoying

This is completely normal Hungarian.

They are nouns made from verbs.

• fúr = to drill

• fúrás = drilling

• kopog = to knock
• kopogás = knocking, knocking sound, or a knock/knocking

The suffix -ás / -és often turns a verb into an action noun, similar to English -ing in some cases.

So these words name the activity or the sound/event itself.

a is the Hungarian definite article, meaning the.

Here it does not necessarily sound as specific in English as the always does. Hungarian often uses the definite article in places where English may or may not use it, especially with known activities, noises, or things being discussed.

So:

• a fúrás = the drilling
• a kopogás = the knocking

In natural English translation, you might still say drilling or the drilling, depending on context.

zavaró means annoying, disturbing, bothersome, or disruptive, depending on context.

It comes from the verb zavar, which can mean to disturb, to bother, to confuse, or to interrupt.

The ending -ó / -ő often creates a participle-like adjective, so zavaró is literally something like disturbing.

In this sentence, annoying or disturbing is the most natural translation.

Hungarian is means also, too, or sometimes even, and it usually comes after the word it belongs to.

So:

• a kopogás is zavaró = the knocking is annoying too
• more literally: the knocking too is annoying

This is very typical Hungarian word order.
You do not put is before the word the way English puts too or also.

Here it most naturally means also or too.

So a kopogás is zavaró means:

• the knocking is also annoying
• the knocking too is annoying

Sometimes is can mean even, but that depends on context and emphasis. In this sentence, also/too is the normal reading.

Because Hungarian often repeats the predicate in parallel structures like this, especially when the speaker wants a clear, balanced sentence.

So:

• Egyrészt a fúrás zavaró, másrészt a kopogás is zavaró.

sounds neat and natural.

English often avoids repetition more than Hungarian does. In Hungarian, repeating zavaró here is not awkward; it is actually the straightforward choice.

Not necessarily. It can show two contrasting sides, but it can also simply present two separate points or two reasons.

In this sentence, the idea is not really this but that. It is more like:

• for one thing, the drilling is annoying
• for another, the knocking is annoying too

So the structure is organizing the complaint into two parts.

Yes, Hungarian word order is flexible, but different orders can change emphasis.

The sentence as given is quite natural and balanced:

• Egyrészt a fúrás zavaró, másrészt a kopogás is zavaró.

If you changed the order, the sentence might still be correct, but the focus could shift. For example:

• Egyrészt zavaró a fúrás...

puts a little more emphasis on zavaró.

The original version is a good neutral pattern for a learner.

The accents in Hungarian mainly show vowel length.

• ú, á, ó, é are long vowels
• they are held a bit longer than their short versions

So:

• fúrás → long ú, long á
• kopogás → long á
• zavaró → long ó
• egyrészt, másrészt → long é

A useful extra point: Hungarian stress is usually on the first syllable of the word.

So roughly:

• FÚ-rás
• KO-po-gás
• ZA-va-ró
• EGY-részt
• MÁS-részt

The accents do not mark stress the way they often do in some other languages; they mainly mark vowel length.
