Dişçi hanımdan yarına randevu aldım; ne olursa olsun gideceğim.

It means the lady dentist or the female dentist, said politely.

In Turkish, a profession word plus hanım is a common respectful way to refer to a woman:

• öğretmen hanım = the lady teacher
• doktor hanım = the lady doctor
• dişçi hanım = the lady dentist

So here hanım is not part of her name. It is a polite title.

Here it means the dentist herself.

In this structure, profession + hanım refers to a woman who has that profession. So dişçi hanım is a female dentist.

If Turkish wanted to say the dentist’s wife, it would usually need a different structure, not this one.

The ending -dan / -den is the ablative case, often meaning from.

With randevu almak, Turkish commonly says you get/take an appointment from a person or institution:

• Doktordan randevu aldım = I got/made an appointment with the doctor
• Dişçi hanımdan randevu aldım = I got/made an appointment with the lady dentist

So the Turkish logic is a bit like:

• I obtained an appointment from her

Even though in natural English we usually say make an appointment with someone.

Literally, randevu aldım means I took/got an appointment.

Yes, this is a very normal Turkish expression. The usual verb is almak:

• randevu almak = to make/get an appointment

So although English normally says make an appointment, Turkish usually says take/get an appointment.

Yarına has the dative ending -a/-e, and here it means for tomorrow.

So:

• yarın = tomorrow
• yarına randevu almak = to make an appointment for tomorrow

This is a very common pattern in Turkish for appointments, plans, deadlines, and similar target times.

A close alternative would be:

• yarın için randevu aldım = I made an appointment for tomorrow

But yarına randevu aldım is very natural.

It means the appointment is for tomorrow.

The past tense is already shown by aldım:

• aldım = I took / I made

So the action of making the appointment happened in the past, and yarına tells you the scheduled day of the appointment.

It is made of these parts:

• ne = what
• olursa = if it happens / if it becomes
• olsun = let it be / may it be

But as a full expression, ne olursa olsun means:

• no matter what happens
• whatever happens
• come what may

So you should learn it mainly as a set phrase, not only word by word.

Olsun is a special form of olmak. It is often called a 3rd person imperative/optative form, something like let it be.

In ne olursa olsun, it helps create the fixed meaning:

• whatever it may be
• no matter what happens

So in this sentence, it is not really a direct command. It is part of a common idiomatic structure.

They are:

• aldım = simple past, 1st person singular
  
  • I got / I made
• gideceğim = future, 1st person singular
  
  • I will go

So the sentence moves from a completed action to a future intention:

• I made an appointment...
• ...and I will go.

Because gitmek behaves irregularly in some forms and uses gid- before certain vowel-initial endings.

So you get:

• gidiyor = he/she is going
• gidecek = he/she will go
• gideceğim = I will go

This is something learners usually just memorize as part of the verb gitmek.

It adds strong determination.

Without it, gideceğim just means I will go.

With ne olursa olsun, the meaning becomes stronger:

• I will go no matter what
• Whatever happens, I’m going

So the speaker is emphasizing that they do not plan to cancel or back out.

Yes. Turkish word order is flexible, although the original sentence is very natural.

For example, you could also hear:

• Yarına dişçi hanımdan randevu aldım.
• Dişçi hanımdan randevu aldım yarına.
  This is less neutral and more marked.

The original order sounds smooth and standard:

• Dişçi hanımdan yarına randevu aldım

It introduces:

1. who the appointment is with
2. when it is for
3. the main action

Dişçi is very common in everyday Turkish.

A more formal and precise term is:

• diş hekimi = dentist

So both are used, but the feeling is different:

• dişçi = everyday, conversational
• diş hekimi = more formal, professional

In this sentence, dişçi sounds completely normal.
