Jeho rada je dobrá.

Because dobrá has to agree with rada.

In Czech, adjectives agree with the noun they describe in:

• gender
• number
• case

Rada is feminine singular nominative here, so dobrý becomes dobrá.

Compare:

• masculine: dobrý
• feminine: dobrá
• neuter: dobré

So rada je dobrá means the adjective is matching a feminine noun.

It is in the nominative singular.

That is because rada is the subject of the sentence: it is the thing that is good. In a basic sentence like this, the subject is normally in the nominative.

Since dobrá describes rada, it is also nominative singular feminine.

No. That is a very common point of confusion.

Jeho means his, and it refers to the owner, not to the gender of rada. So even though rada is feminine, you still use jeho if the owner is male.

For example:

• jeho rada = his advice
• jeho sestra = his sister
• jeho auto = his car

So jeho stays the same with masculine, feminine, and neuter nouns.

Usually, learners first notice that jeho seems much less changeable than words like můj or tvůj.

In standard Czech, jeho is generally treated as an indeclinable possessive form, so it stays jeho in normal use.

That is different from:

• můj = my
• tvůj = your

Those do change:

• moje rada
• mého bratra
• mému kamarádovi

But jeho remains jeho:

• jeho rada
• bez jeho rady
• k jeho domu

In a normal standard sentence, yes, you should keep je.

Je is the 3rd person singular of být = to be. In Czech, the verb to be is normally expressed in sentences like this:

• Jeho rada je dobrá.

You cannot normally drop it the way Russian does. Czech often drops subject pronouns, but not the present-tense je in a basic statement like this.

Yes, Czech word order is flexible, but the neutral order here is:

Jeho rada je dobrá.

That is the most natural version for a beginner to use.

Other orders are possible, but they change emphasis:

• Dobrá je jeho rada. = more literary or emphatic
• Je dobrá jeho rada? = question-like structure

So the words can move, but the basic sentence you should learn first is the original one.

Not always. Rada can mean different things depending on context.

Common meanings include:

• advice
• a piece of advice
• council or board

In this sentence, the most natural meaning is advice.

Also, do not confuse rada with ráda:

• rada = advice, council
• ráda = glad, willingly, used with a female speaker

Those are different words.

A rough English-friendly guide is:

YE-ho RA-da ye DO-braa

A few useful points:

• j sounds like English y
• h is pronounced
• r should be a Czech-style rolled or tapped r
• á is a long vowel, so the last syllable of dobrá is longer

Czech stress is usually on the first syllable of each word.

Because Czech does not have articles like English.

So rada can mean:

• advice
• the advice
• a piece of advice

The exact meaning depends on context.

That is why Jeho rada je dobrá can be understood naturally without adding anything equivalent to the or a.

Czech rada is often used as a normal singular countable noun meaning a piece of advice or advice in a general sense.

So Czech can say:

• To je dobrá rada. = That is good advice / That is a good piece of advice.

English usually prefers uncountable advice, but Czech often uses rada quite naturally in the singular. So this is normal Czech, even if the English translation may sound a little different structurally.
