Poradíme se a uhodneme odpověď.

Because both verbs are perfective:

• poradit se = to consult, discuss and reach a result
• uhodnout = to guess correctly

In Czech, perfective verbs do not normally have a true present meaning. Their present-tense forms are used for future meaning.

So:

• poradíme se = we will consult / we’ll talk it over
• uhodneme = we will guess

This is very common in Czech. Compare:

• uděláme = we will do
• řeknu = I will say
• najdu = I will find

So the form looks present, but with a perfective verb it usually refers to a completed action in the future.

Se is a reflexive particle. In this verb, it is part of the expression poradit se.

Here, poradit se means something like:

• to consult
• to talk something over
• to confer
• sometimes to ask for advice

In poradíme se, the meaning is often naturally we’ll consult with each other or we’ll talk it over.

So you should learn poradit se as a whole verb phrase, not just poradit + se added freely.

The dictionary form is poradit se.

Its forms are:

• já poradím se
• ty poradíš se
• on/ona poradí se
• my poradíme se
• vy poradíte se
• oni poradí se

In real Czech, the reflexive particle often moves to the second position in the sentence, so you may see word orders like:

• Poradíme se.
• My se poradíme.

The important thing is that the verb is poradit se.

The dictionary form is uhodnout.

It means:

• to guess
• more precisely, to guess correctly

So uhodneme odpověď means we will guess the answer correctly or simply we’ll guess the answer.

This is slightly different from just making random guesses. The verb suggests getting it right.

This is mainly a question of aspect.

• hádat = imperfective
  
  • focuses on the process, repeated action, or ongoing guessing
  • Hádej! = Keep guessing / Take a guess
• uhodnout = perfective
  
  • focuses on reaching the result: guessing correctly

So:

• Budeme hádat odpověď. = We will be guessing the answer.
• Uhodneme odpověď. = We will guess the answer / We’ll get the answer right.

In your sentence, uhodneme fits because it presents the action as a completed result.

Odpověď is the direct object of uhodneme, so it is in the accusative case.

However, for this noun, the nominative singular and accusative singular have the same form:

• nominative: odpověď
• accusative: odpověď

So the case does change grammatically, but the form happens to stay the same.

This is normal for many feminine nouns in Czech.

By itself, odpověď means answer, but Czech often does not use articles like a or the, because Czech has no articles.

So depending on context, odpověď can mean:

• an answer
• the answer

In this sentence, the natural English translation is usually the answer, because you are probably talking about a specific answer.

Yes. A simply means and.

So the sentence has two coordinated actions:

• Poradíme se = We’ll consult / talk it over
• a
• uhodneme odpověď = and we’ll guess the answer

Very straightforward.

Not literally, at least not as the most direct grammatical reading.

Poradíme se and uhodneme are formally 1st person plural present forms of perfective verbs, which usually mean future:

• we will consult
• we will guess

If you want a clear imperative let’s ..., Czech normally uses:

• Poraďme se a uhodněme odpověď.

That said, in some real-life contexts, Czech speakers can use future-like forms in a very conversational way, but for a learner, the safest interpretation here is:

• We’ll consult and guess the answer.

Not exactly.

• radit = to advise, to give advice
• poradit = to advise once / to manage to advise / to solve by advice, depending on context
• poradit se = to consult, to ask for advice, to talk something over

So in your sentence, poradíme se does not mean we will advise. It means we will consult / discuss it together.

Yes, Czech word order is flexible.

Your sentence:

• Poradíme se a uhodneme odpověď.

is perfectly natural.

But Czech can move words around for emphasis, for example:

• Odpověď uhodneme, až se poradíme. = We’ll guess the answer once we’ve consulted.
• Nejdřív se poradíme a potom uhodneme odpověď. = First we’ll consult and then we’ll guess the answer.

Still, the original word order is simple and neutral.

A simple learner-friendly pronunciation guide is:

• Poradíme se a uhodneme odpověď.
• approximately: po-ra-DEE-me se a U-ho-dne-me OT-po-vyet

A few useful points:

• ř in odpověď is a special Czech sound, but note that this word actually has ď, not ř
• ď is a soft d sound
• ě after v in odpověď sounds roughly like vye
• stress in Czech is usually on the first syllable of each word:
  • POradíme
  • SE
  • A
  • Uhodneme
  • ODpověď

Yes, it is understandable and natural enough, especially in a simple learning context.

A native speaker might also say things like:

• Poradíme se a tipneme odpověď.
• Poradíme se a zkusíme uhodnout odpověď.
• Domluvíme se a uhodneme správnou odpověď.

But your sentence is grammatically fine and easy to understand. It gives good practice with:

• a reflexive verb: poradit se
• a perfective verb with future meaning: uhodneme
• a direct object: odpověď
