Zjistili jsme správnou odpověď.

Because Czech past tense is usually made with:

• a past participle: zjistili
• plus a short form of být (to be): jsme

So zjistili jsme literally works like found out + we have/were, but in natural English it simply means we found out / we discovered.

This is the normal way to form the past tense in Czech:

• zjistil jsem = I found out
• zjistili jsme = we found out
• zjistila = she found out

In the 3rd person, Czech usually does not use the auxiliary:

• zjistil = he found out
• zjistili = they found out

Zjistili is the past participle of zjistit, which means to find out, to discover, or to ascertain.

In this sentence, zjistili agrees with the subject we. The ending -i shows a plural form used with a group that is either:

• all male, or
• mixed gender

If the group were all female, you would say:

• Zjistily jsme správnou odpověď.

So the sentence as written most naturally suggests either a mixed group or a group of men.

Because Czech often leaves out subject pronouns when they are already clear from the verb form.

Here, jsme already tells you the subject is we, so my is unnecessary:

• Zjistili jsme správnou odpověď. = normal
• My jsme zjistili správnou odpověď. = possible, but adds emphasis, like We found out the correct answer.

This is very common in Czech.

Because správnou odpověď is the direct object of the verb zjistit, so it must be in the accusative case.

The dictionary form is:

• správná odpověď = the correct answer

But after the verb, as the thing that was found out, it becomes accusative:

• správnou odpověď

So the changes are:

• správná → správnou
• odpověď stays odpověď

This happens because:

• správná is a feminine adjective, and its accusative singular form is správnou
• odpověď is a feminine noun, but in this pattern its accusative singular looks the same as the nominative

Because nouns and adjectives do not always change in the same visible way.

Odpověď is a feminine noun, but its accusative singular form is identical to its nominative singular form:

• nominative: odpověď
• accusative: odpověď

However, the adjective must still agree with it in gender, number, and case, so:

• nominative: správná odpověď
• accusative: správnou odpověď

This is a very common pattern in Czech: sometimes the case is shown more clearly on the adjective than on the noun.

Zjistit is perfective.

That matters because perfective verbs usually describe a completed action or a result. So Zjistili jsme správnou odpověď means that the answer was successfully found out — the action reached its endpoint.

The imperfective partner is usually zjišťovat:

• Zjišťovali jsme správnou odpověď. = We were finding out / trying to determine the correct answer.

So:

• zjistit = to find out, to determine successfully
• zjišťovat = to be finding out, to investigate, to determine over time

In your sentence, the perfective verb fits because the result has been achieved.

In standard Czech, ne in normal neutral word order.

The short auxiliary jsme usually takes the second position in the clause, which is why Zjistili jsme is natural.

So:

• Zjistili jsme správnou odpověď. = normal

You may also see other word orders depending on emphasis:

• Správnou odpověď jsme zjistili.
• My jsme zjistili správnou odpověď.

But Jsme zjistili... is not the normal standard placement in an ordinary sentence.

Yes, Czech word order is fairly flexible, but changing it usually changes the focus or emphasis, not the core meaning.

Examples:

• Zjistili jsme správnou odpověď.
  Neutral: We found out the correct answer.

• Správnou odpověď jsme zjistili.
  Emphasis on the correct answer.

• My jsme zjistili správnou odpověď.
  Emphasis on we.

So the basic meaning stays the same, but the information structure changes.

A rough pronunciation guide for an English speaker is:

• Zjistili ≈ z-yis-ti-li
• jsme ≈ yz-me or sme in fast speech
• správnou ≈ spraav-noh
• odpověď ≈ ot-po-vyetch

A few useful points:

• zj at the beginning can feel tricky; say it smoothly, almost like z + y
• á is a long vowel
• ou is like oh in this word
• ď is a soft consonant, somewhat like a softened d

You do not need perfect pronunciation immediately; the hardest parts for many learners are zj- and the final -ď.

Sometimes yes, but found out or discovered is often closer to zjistili.

Compare:

• našli jsme správnou odpověď = we found the correct answer
  more literally found

• zjistili jsme správnou odpověď = we found out / determined / discovered the correct answer

So zjistit often focuses more on arriving at the right information, not just physically or abstractly finding something. In many contexts, though, We found the correct answer is a perfectly natural English translation.
