Miodarka jest gotowa.

Because it agrees with miodarka, which is a feminine singular noun.

In Polish, adjectives change their form to match the noun’s:

• gender
• number
• usually also case

Here:

• miodarka = feminine singular
• so gotowy becomes gotowa

Compare:

• miodarka jest gotowa = the honey extractor is ready
• sprzęt jest gotowy = the equipment is ready (sprzęt is masculine)
• urządzenie jest gotowe = the device is ready (urządzenie is neuter)

No. In Polish, grammatical gender is a grammar category, not biological sex.

Miodarka is feminine because nouns ending in -a are very often feminine. That does not mean the object is literally female.

This is very common in Polish:

• książka = book → feminine
• lodówka = fridge → feminine
• miodarka = honey extractor → feminine

So the adjective must match the noun’s grammatical gender, not real-world sex.

Jest is the 3rd person singular present tense of być = to be.

So:

• być = to be
• jest = is

In this sentence:

• miodarka = subject
• jest = verb
• gotowa = predicate adjective

So the structure is basically:

• Miodarka jest gotowa.
• The honey extractor is ready.

Sometimes, yes, but it is more elliptical and less neutral.

The full, standard sentence is:

• Miodarka jest gotowa.

You may also hear:

• Miodarka gotowa.

That shorter version can sound like:

• a status update
• a label
• a headline
• a spoken shortcut

For a learner, the safest normal form is with jest.

Because Polish has no articles.

English distinguishes:

• a honey extractor
• the honey extractor

Polish usually just says:

• miodarka

The exact meaning depends on context.

So Miodarka jest gotowa could mean:

• The honey extractor is ready
• A honey extractor is ready

In real use, the situation normally makes it clear which one is meant.

It is in the nominative case because it is the subject of the sentence.

The basic dictionary form of the noun is:

• miodarka

And that is also the form used here.

You can think of it like this:

• Who/what is ready?
• Miodarka is ready.

So nominative is exactly what we expect.

Because gotowa is an adjective, not a noun.

After być in Polish:

• a predicate adjective usually stays in the nominative
• a predicate noun is often in the instrumental

Compare:

Adjective

• Miodarka jest gotowa. = The honey extractor is ready.

Noun

• Ona jest nauczycielką. = She is a teacher.
  Here nauczycielką is instrumental.

So gotowa stays in the normal adjective form matching the subject.

Yes, Polish word order is more flexible than English, but not all orders sound equally neutral.

The most natural neutral order here is:

• Miodarka jest gotowa.

Other orders are possible, but they add emphasis or sound marked:

• Gotowa jest miodarka. = emphasizes gotowa
• Jest gotowa miodarka. = much less natural in isolation

For learners, it is best to stick with:

• subject + jest + adjective

A simple approximation is:

• mio-DAR-ka yest go-TO-va

A few useful notes:

• Polish stress is usually on the second-to-last syllable
• so:
  • mio-DAR-ka
  • GO-to-va
• j in Polish sounds like English y
  • so jest sounds like yest
• w in Polish sounds like English v
  • so gotowa ends with a va sound

The base dictionary form is gotowy.

This adjective changes depending on gender:

• gotowy = masculine
• gotowa = feminine
• gotowe = neuter

Examples:

• samochód jest gotowy = the car is ready
• miodarka jest gotowa = the honey extractor is ready
• urządzenie jest gotowe = the device is ready

So when you look the word up, you usually find gotowy.

You add nie before jest:

• Miodarka nie jest gotowa. = The honey extractor is not ready.

That is the normal way to negate this kind of sentence.

You can also notice that:

• nie goes directly before the verb
• the adjective gotowa does not change just because the sentence is negative

Its main meaning is ready, prepared, or finished being prepared, depending on context.

So Miodarka jest gotowa could suggest:

• it is ready to use
• it has been prepared
• it is set up and can now be used

As in English, the exact nuance depends on the situation.

Not for most people. It is a specialized noun, mostly used in the context of beekeeping.

It refers to a honey extractor, a machine used to extract honey from honeycombs.

Even if the word itself is specialized, the grammar in the sentence is very ordinary:

• noun in nominative
• jest
• adjective agreeing with the noun

So it is a good sentence for learning basic Polish structure.
