Likvidátor dokázal najít příčinu.

Not necessarily. Likvidátor can sometimes look like the English word liquidator, but in Czech it can also mean a person who eliminates, deals with, or in some contexts an insurance claims adjuster/investigator.

So this is a good word to treat carefully as a possible false friend. The exact meaning depends on context.

Grammatically, likvidátor is:

• masculine animate
• singular
• in the nominative case here, because it is the subject of the sentence

Dokázal is the past tense of the verb dokázat.

In sentences like this, dokázat + infinitive often means:

• to manage to do something
• to succeed in doing something
• sometimes to be able to do something

So:

• dokázal najít = managed to find / was able to find

Depending on context, dokázat can also mean to prove, but that is not the meaning here.

Because Czech often uses one verb to express the idea of success or ability, and a second verb in the infinitive to say what was done.

Here:

• dokázal = managed / was able
• najít = to find

Together:

• dokázal najít = managed to find

If you just said našel, that would simply mean found.
But dokázal najít adds the nuance that finding it required effort or was an achievement.

Najít is the infinitive form of the verb, meaning to find.

It is also a perfective verb. That means it refers to finding something as a completed result.

A useful pair is:

• hledat = to look for / search for (imperfective)
• najít = to find (perfective)

So the sentence is about successfully reaching the result: finding the cause.

Because it is the direct object of the verb, so it appears in the accusative case.

The dictionary form is:

• příčina = cause

But in the accusative singular:

• příčinu

This happens because příčina is a feminine noun.

So:

• příčina = nominative singular
• příčinu = accusative singular

In Czech, case endings usually show the role of a word in the sentence.

Here:

• Likvidátor is in the nominative → the subject
• příčinu is in the accusative → the direct object

So even if the word order changed, the endings would still help you understand who did what.

The -l is part of the Czech past tense form.

Dokázal tells us that the subject is:

• masculine
• singular

Compare:

• dokázal = he managed / a masculine subject managed
• dokázala = she managed / a feminine subject managed
• dokázalo = it managed (neuter)
• dokázali = they managed (masculine animate or mixed group)
• dokázaly = they managed (non-masculine-animate)

Since the subject is likvidátor, masculine singular, dokázal matches it.

No, Czech word order is fairly flexible, because cases show grammatical roles.

This sentence uses a very neutral order:

• subject + finite verb + infinitive + object

That is:

• Likvidátor
  • dokázal
    • najít
      • příčinu

You could change the order for emphasis, for example:

• Příčinu dokázal likvidátor najít.
• Najít příčinu dokázal likvidátor.

These alternatives are possible, but the original sentence sounds like the most straightforward, neutral version.

Yes, that is normal.

• dokázat is perfective: it presents the success as a completed fact
• najít is perfective: it presents the finding as a completed result

So the whole sentence emphasizes a completed achievement:

• he managed
• and he found the cause

This combination is very natural in Czech.

No, not in this exact structure.

When dokázat means to prove, it usually takes a direct object, for example:

• dokázal něco = he proved something

But here we have:

• dokázal najít
  • infinitive

That structure means managed to find or was able to find, not proved.

A rough pronunciation guide is:

Likvidátor dokázal najít příčinu
LIK-vi-daa-tor do-KAA-zal na-YEET PRZHEE-chi-noo

A few useful points:

• Czech stress is usually on the first syllable of each word:
  • LIkvidátor
  • DOkázal
  • NAjít
  • PŘÍčinu
• á, í, ů, etc. mark long vowels
• ř is a special Czech sound that English speakers usually need time to learn

You do not need perfect pronunciation right away, but it helps to notice the long vowels in:

• likvidátor
• najít
• příčinu

This is a very useful distinction.

• dokázal najít = managed to find, succeeded in finding
• mohl najít = could find, was able to find, sometimes only expressing possibility or ability

So:

• dokázal najít příčinu strongly suggests that he actually did find the cause
• mohl najít příčinu could mean he had the ability/opportunity to find it, depending on context

So dokázal is stronger and more result-focused.

The past tense verb would change to agree with the subject.

For example:

• Likvidátorka dokázala najít příčinu.

Here:

• likvidátorka = feminine noun
• dokázala = feminine singular past tense

The rest stays the same:

• najít = infinitive
• příčinu = accusative singular object
