Краплі готові.

In Ukrainian, the present-tense verb to be is usually not expressed in simple sentences like this.

So:

• Краплі готові. = The drops are ready.

Literally, Ukrainian says something like Drops ready.

This is completely normal. English needs are, but Ukrainian usually leaves it out in the present tense.

Краплі is plural.

Its dictionary form is крапля = a drop.

So:

• крапля = one drop
• краплі = drops

Depending on context, краплі can mean:

• physical drops / droplets
• medicinal drops, such as eye drops or nose drops

In everyday usage, very often it refers to medicine drops if the context suggests that.

Because it agrees with the noun краплі, which is plural.

The adjective готовий means ready in its basic dictionary form.
Its forms change to match the noun:

• готовий — masculine singular
• готова — feminine singular
• готове — neuter singular
• готові — plural

Since краплі is plural, you need готові.

The singular would be:

• Крапля готова. = The drop is ready.

Here:

• крапля is singular
• готова is the feminine singular form of ready

That is because крапля is a feminine noun.

Here краплі is in the nominative plural.

It is the subject of the sentence:

• Краплі готові. = The drops are ready.

So this is a straightforward nominative subject + predicate adjective structure.

A learner may notice that краплі can also be another case form in other contexts, but in this sentence it is understood as nominative plural.

A helpful pronunciation guide is:

• Кра́плі — KRA-pli
• гото́ві — ho-TO-vi

A few useful notes:

• The stress is on КРА́плі
• The stress is on то́ in гото́ві
• Ukrainian г is usually pronounced like a soft English h, not like a hard g

So the whole sentence sounds roughly like:

• KRA-pli ho-TO-vi

Yes. Very often краплі can refer to medicinal drops, but the exact kind depends on context.

For example:

• очні краплі = eye drops
• краплі для носа = nose drops
• вушні краплі = ear drops

If someone simply says Краплі готові, the listener usually understands the exact meaning from the situation.

Yes, but it means something slightly different in structure.

• Краплі готові. = The drops are ready.
• Готові краплі = ready drops

So:

• Краплі готові is a complete sentence.
• Готові краплі is usually a noun phrase, not a full statement by itself.

Word order can change emphasis, but the basic distinction is:

• noun + adjective = often a statement
• adjective + noun = often just a phrase

Usually, no need.

In normal Ukrainian, the present-tense to be is omitted:

• Краплі готові.

Adding є is usually unnecessary here and can sound unnatural in a basic sentence like this.

So the natural version is simply:

• Краплі готові.

It mostly means ready, but in some contexts it can also feel like prepared.

So Краплі готові could mean:

• the drops are ready
• the drops have been prepared

If you want to stress that something has been specifically prepared, Ukrainian may also use other words depending on context, but готові is very natural for ready.

It is neutral and completely natural.

It can be used in:

• everyday speech
• instructions
• a medical setting
• a pharmacy or clinic
• household conversation

There is nothing especially formal or slangy about it.

Yes, very naturally.

For example:

• Уже можна? — Краплі готові.
  Can we use them now? — The drops are ready.

Ukrainian often uses short, compact sentences like this, especially when the context is clear.
