Bu ilaçtan uzak dur.

Bu means this. It points to something near the speaker or already being discussed.

So:

• bu ilaç = this medicine / this drug

Unlike English, Turkish does not use articles like a or the, so bu is enough to specify this.

Because Turkish uses the ablative suffix here, which often means from.

• ilaç = medicine, drug
• ilaçtan = from the medicine / away from the medicine

In Bu ilaçtan uzak dur, the idea is literally something like:

• Stay far from this medicine

So -tan is necessary because uzak durmak normally goes with something in the ablative.

-tan is one form of the ablative case suffix, which commonly means:

• from
• away from
• out of

Examples:

• evden = from the house
• okuldan = from school
• ilaçtan = from the medicine

In this sentence, it marks what you should keep away from.

This is because of consonant harmony in Turkish.

The ablative suffix has forms like:

• -dan / -den
• -tan / -ten

After a voiceless consonant, Turkish usually uses t instead of d.

Since ilaç ends in ç, which is voiceless, you get:

• ilaç + dan → ilaçtan

So it is not random; it follows a regular sound rule.

Uzak dur means stay away.

It comes from:

• uzak = far, distant
• durmak = to stand, stop, remain

But together, uzak durmak is an expression meaning:

• to keep away
• to stay away

So this is a set phrase, not just two completely separate words translated one by one.

Yes. Dur here is the imperative form of durmak for you (singular, informal).

• durmak = to stay / stand / stop
• dur = stay! / stop!

In uzak dur, it means stay away!

So the full sentence is a direct command to one person.

Yes, Bu ilaçtan uzak dur is the singular informal imperative.

If you want to be polite or address multiple people, use:

• Bu ilaçtan uzak durun.

Here, durun is the polite/plural imperative form.

So:

• uzak dur = stay away (to one person, informal)
• uzak durun = stay away (polite or plural)

İlaç usually means medicine, medication, or remedy. Depending on context, English might translate it as drug too.

So Bu ilaçtan uzak dur could mean:

• Stay away from this medicine.
• Avoid this medication.
• Stay away from this drug.

The exact English wording depends on the situation.

The word order is very natural for Turkish.

• Bu ilaçtan = from this medicine
• uzak dur = stay away

Turkish often puts the thing being referred to before the verb or verb phrase. So this structure is normal.

A very literal breakdown is:

• This medicine-from away stay

But in natural English, that becomes:

• Stay away from this medicine.

Yes, but that changes the form.

• uzak dur = imperative, a command: stay away
• uzak durmak = infinitive: to stay away

So:

• Bu ilaçtan uzak dur. = Stay away from this medicine.
• Bu ilaçtan uzak durmak önemli. = It is important to stay away from this medicine.

So dur and durmak are not interchangeable; they do different jobs.

It usually sounds like a warning or a strong instruction.

Depending on tone and context, it can mean:

• serious advice
• a warning
• a firm order

Because it is an imperative, it is more direct than something softer like:

• Bu ilacı kullanma. = Don’t use this medicine.
• Bu ilaçtan uzak durmalısın. = You should stay away from this medicine.

So Bu ilaçtan uzak dur feels quite direct.
