Předpověď je špatná.

A rough pronunciation is:

Předpověď je špatná
≈ PRZHED-poh-vyet yeh SHPAT-naa

A few tricky sounds:

• ř is a special Czech sound. English does not have it. It is something like a rolled r mixed with zh.
• ě usually softens the consonant before it.
• ď is a soft d sound, a bit like dy in duke for many English speakers.
• š sounds like sh in shoe.
• á is a long vowel, so hold it a little longer.

You do not need perfect pronunciation right away; ř is famously difficult even for learners at a high level.

The sentence breaks down like this:

• předpověď = forecast / prediction
  This is the subject.
• je = is
  This is the 3rd person singular of být (to be).
• špatná = bad
  This is the adjective describing předpověď.

So the structure is:

subject + is + adjective

Very similar to English: The forecast is bad.

Because it has to agree with předpověď.

In Czech, adjectives change their endings to match the noun in:

• gender
• number
• case

Předpověď is:

• feminine
• singular
• nominative

So the adjective must also be feminine singular nominative:

• masculine: špatný
• feminine: špatná
• neuter: špatné

That is why you get špatná here.

You usually learn the gender as part of the noun.

Předpověď is a feminine noun, even though it does not end in -a. That can surprise English speakers, because many feminine nouns do end in -a, but not all of them.

A lot of feminine nouns in Czech end in a soft consonant, including words like:

• dlaň = palm of the hand
• odpověď = answer
• předpověď = forecast / prediction

So with předpověď, you simply need to memorize that it is feminine.

It is in the nominative singular.

Why?

Because předpověď is the subject of the sentence, and subjects are normally in the nominative.

Also, after je in this kind of sentence, the adjective špatná is also nominative, because it is a predicate adjective agreeing with the subject.

So both main content words are effectively in nominative singular feminine:

• předpověď
• špatná

Czech does not have articles like English a and the.

So Předpověď je špatná can mean:

• The forecast is bad
• A forecast is bad

In real life, context tells you which meaning is intended. In many situations, English will naturally use the, but Czech simply does not need a separate word for it.

Not always.

Předpověď can mean:

• forecast
• prediction

So by itself it can be fairly general.

If you want to make it clearly about weather, Czech often says:

• předpověď počasí = weather forecast

But in context, předpověď alone is often understood as a weather forecast, especially if you are talking about rain, temperature, the weekend, and so on.

In the present tense, usually no in this kind of normal statement.

So you say:

• Předpověď je špatná.

Not normally:

• Předpověď špatná.

Czech does sometimes omit to be in headlines, notes, or very informal elliptical style, but in a standard full sentence you keep je.

In the past tense or future, forms of být are also used normally.

Not completely.

The neutral, standard order is:

• Předpověď je špatná.

But Czech word order is more flexible than English. You can change it for emphasis or style. For example:

• Špatná je předpověď.
• Je špatná předpověď.

These are possible in certain contexts, but they do not sound as neutral as the basic version.

For most learners, the safest choice is:

Předpověď je špatná.

It can mean several related things, depending on context:

• bad
• poor
• wrong
• faulty
• nasty or not good

In this sentence, the natural meaning is simply bad.

With a forecast, that could mean:

• inaccurate
• unfavorable
• disappointing

The exact nuance comes from context.

Because that is part of the normal spelling of the word předpověď.

The final ď shows a soft d sound. In Czech, letters like ď, ť, and ň represent softened consonants.

This is important because the softness is part of the word’s form and affects how it behaves in declension. So it is not optional spelling; it is a real part of the noun.

You put není instead of je:

• Předpověď není špatná. = The forecast is not bad.

This is the normal way to negate je:

• je = is
• není = is not

You need both the noun and the adjective in plural, and the verb changes too:

• Předpovědi jsou špatné.

Breakdown:

• předpovědi = forecasts
• jsou = are
• špatné = bad, plural form here

So Czech changes more than English does, because agreement matters throughout the sentence.
