Snad bude zítra pršet.

In this sentence, snad expresses hope or possibility. Depending on context, Snad bude zítra pršet can mean:

• Hopefully it will rain tomorrow
• Perhaps it will rain tomorrow
• I hope it will rain tomorrow

So snad is a small word that adds the speaker’s attitude: the speaker thinks rain is possible and may also be wishing for it.

Because pršet is an imperfective verb, and in Czech the future of imperfective verbs is usually formed with:

future of být + infinitive

So:

• bude = will
• pršet = to rain

Together, bude pršet = will rain

This is a very common pattern in Czech:

• budu dělat = I will do / I will be doing
• bude spát = he/she will sleep
• budeme čekat = we will wait

Yes, pršet is the infinitive.

• prší = it is raining
• bude pršet = it will rain

After the future form of být, Czech uses the infinitive of the imperfective verb. So bude pršet is the normal way to say it will rain.

Czech does not need a dummy subject like English it in weather expressions.

English requires it:

• It is raining
• It will rain

Czech does not:

• Prší
• Bude pršet

So in Czech, weather verbs are often used without any subject at all.

Bude is the 3rd person singular future form of být.

That is the form Czech uses with impersonal weather expressions like:

• bude pršet = it will rain
• bude sněžit = it will snow
• bude mrznout = it will freeze

Even though there is no expressed subject, Czech still uses the 3rd person singular verb form.

Here zítra is an adverb, meaning tomorrow.

So it does not behave like a noun here, and you do not need to think of it as taking a case in this sentence. It simply tells you when the action will happen.

Compare:

• dnes = today
• zítra = tomorrow
• včera = yesterday

These are time adverbs.

Yes, Czech word order is fairly flexible, but the change affects emphasis and naturalness.

The sentence:

Snad bude zítra pršet.

is a very natural way to say it.

Other possible orders include:

• Zítra bude snad pršet.
• Snad zítra bude pršet.
• Bude zítra pršet. = Will it rain tomorrow? if said with question intonation / written with a question mark

Even when the basic meaning stays similar, the placement of snad or zítra can shift what sounds more prominent. For a learner, Snad bude zítra pršet is a good standard model.

Both can sometimes be translated as maybe / perhaps, but they are not always identical.

• možná usually means maybe / perhaps
• snad can mean hopefully, perhaps, or I hope, depending on context

So:

• Možná bude zítra pršet. = Maybe it will rain tomorrow.
• Snad bude zítra pršet. = Hopefully / perhaps it will rain tomorrow.

Snad often feels a bit more connected to the speaker’s wish or expectation.

Doufám, že bude zítra pršet means I hope it will rain tomorrow very explicitly.

• Doufám, že... = I hope that...
• Snad... = more compact, less explicit, and sometimes a bit softer

So:

• Snad bude zítra pršet. = hopefully / perhaps it will rain tomorrow
• Doufám, že bude zítra pršet. = I hope it will rain tomorrow

If you want to state your hope very clearly, Doufám, že... is the stronger and more direct option.

Usually just will rain.

Czech does not divide things the same way English does with will rain versus will be raining. The form bude pršet is the normal future expression and can cover what English might express in different ways depending on context.

So in most cases, you should simply translate it as:

bude pršet = it will rain

The main thing English speakers often notice is the Czech sound ř, which appears in both zítra and pršet.

Roughly:

• zítra sounds approximately like ZEE-tra, but with the special Czech ř-family sound affecting the cluster
• pršet has the same tricky consonant sound

Also remember that Czech stress is usually on the first syllable of the word:

• ZÍ-tra
• PR-šet
• SNAD
• BU-de

The exact sound ř is difficult for many learners, so it is completely normal if it takes practice.
