Plan hazırdı, ne var ki kimse gelmedi.

Hazırdı means was ready.

It is made from:

• hazır = ready
• -dı = past form of the copula, giving the idea of was

So Plan hazırdı means The plan was ready.

This is a very common Turkish pattern: a noun or adjective can act as the predicate, and Turkish adds a past ending instead of using a separate word like English was.

Both are possible in principle, because -dı here comes from idi.

So:

• hazır idi
• hazırdı

mean the same thing.

In modern Turkish, the attached form is much more common and natural in everyday writing and speech. So learners will usually see hazırdı, güzeldi, zordu, and so on.

Ne var ki is a fixed expression meaning something like:

• but
• however
• and yet
• nevertheless

In this sentence, it introduces a contrast:

• Plan hazırdı = everything seemed ready
• ne var ki kimse gelmedi = but despite that, nobody came

So it connects two ideas that go against each other.

Not very well.

If you try to break it apart, it may look like something involving what is there that..., but that is not how you should understand it in normal use. As a learner, it is best to treat ne var ki as one set phrase meaning however / but / yet.

Because this ki is a separate conjunction/particle, not a suffix.

In Turkish:

• conjunction ki is written separately
• suffix -ki is written attached

For example:

• ne var ki → separate
• evdeki = the one in the house → attached

So in this sentence, ki is separate because it belongs to the fixed connective expression ne var ki.

Turkish does not have a definite article like English the.

So plan can mean:

• the plan
• sometimes just plan, depending on context

Here, it is understood as the plan because the context makes it specific. That is very normal in Turkish.

Here kimse means nobody / no one.

A very important point for English speakers: in Turkish, words like kimse often appear together with a negative verb.

So:

• kimse gelmedi = nobody came

This is normal Turkish grammar. It is not considered a wrong double negative.

You can also hear:

• hiç kimse gelmedi = absolutely nobody came

That is a stronger or more explicit version.

Gelmedi breaks down as:

• gel- = come
• -me- = negation
• -di = past tense

So gelmedi means did not come.

In the full clause:

• kimse gelmedi = nobody came

Even though English uses nobody came, Turkish uses the negative verb form.

Because kimse is treated grammatically as singular.

So Turkish normally uses third person singular:

• kimse gelmedi

not

• kimse gelmediler

Even though the meaning refers to the absence of any people, the grammar stays singular.

Yes. A very natural alternative is:

Plan hazırdı ama kimse gelmedi.

That also means The plan was ready, but nobody came.

The difference is mostly style:

• ama = very common, neutral, everyday
• fakat = also common, a little more formal
• ne var ki = more literary, more emphatic, closer to however / and yet

So ne var ki sounds a bit stronger and more polished than ama.

The comma separates the two clauses and helps mark the contrast introduced by ne var ki:

• Plan hazırdı,
• ne var ki kimse gelmedi.

This punctuation is natural and standard in writing. It makes the sentence easier to read and shows that the second part is a contrasting follow-up to the first.

This word order is completely natural.

Turkish word order is flexible, but this version is a standard, clear way to say it:

• first clause: Plan hazırdı
• contrast marker: ne var ki
• second clause: kimse gelmedi

You may see other structures in different styles, but for a learner, this sentence is a very good model to remember.
