Aman, boş ver o rezaleti.

Aman is an interjection. It does not change the basic grammar; it adds emotion and attitude.

In this sentence, it gives a feeling like:

• oh, come on
• for heaven’s sake
• ah, never mind

So it makes the whole sentence sound more dismissive, impatient, or trying to move on from the topic.

Boş ver is the imperative form of boş vermek, which is a very common Turkish expression.

Even though the parts are literally:

• boş = empty
• vermek = to give

the phrase boş vermek is idiomatic. You should learn it as a whole expression meaning things like:

• let it go
• forget it
• don’t worry about it
• ignore it

So this is not a case where the literal meanings of the individual words help much.

Because this is a command.

In Turkish, the informal singular imperative usually uses the bare verb stem:

• vermek = to give
• ver = give

Since boş vermek is the full expression, its command form is boş ver.

The subject sen is understood and normally left out, so boş ver means you, forget it / let it go.

Here, -i is the accusative ending, marking a specific direct object.

So:

• rezalet = disgrace, mess, fiasco
• rezaleti = the disgrace / that mess, as the direct object

This happens because boş vermek takes an object, and here the speaker is talking about a specific thing.

So the structure is basically:

• boş ver = forget / ignore
• o rezaleti = that disgrace / that mess

This -i is not possessive here; it is the definite object marker.

O means that.

It points to a specific thing already known in the conversation. So o rezaleti means that mess / that disgrace / that fiasco, not just a mess in general.

Without o, the sentence would feel a little less pointed. With o, the speaker is clearly referring to that particular situation.

The more neutral Turkish word order is often object + verb, so:

• O rezaleti boş ver.

would also be very normal.

But in spoken Turkish, especially with short commands and fixed expressions, it is very common to put the command phrase first:

• Boş ver o rezaleti.

This makes the sentence feel more immediate and conversational. The speaker blurts out the main action first: Forget it — and then specifies what.

So this word order is natural, especially in speech.

It is mostly casual and conversational.

You would hear it a lot in everyday speech between friends, family members, or people speaking informally.

If you wanted to be more polite or address more than one person, you would use:

• boş verin

So:

• Aman, boş ver o rezaleti. = informal singular
• Aman, boş verin o rezaleti. = polite or plural

Yes, it can, depending on tone of voice and context.

It can sound:

• comforting, if someone is upset and you mean let it go
• dismissive, if you seem to be brushing off something important
• impatient, especially because of aman

So the sentence itself is not automatically rude, but it definitely has a strong, colloquial tone. If someone is very upset, saying this too sharply could sound like you are not taking their feelings seriously.

Rezalet is fairly strong. It usually refers to something very bad, embarrassing, chaotic, or disgraceful.

Depending on context, it can mean something like:

• a disgrace
• a fiasco
• a mess
• an embarrassment

It is stronger than a neutral word like problem. So the sentence is not just saying ignore that issue; it suggests the thing being discussed was really awful or shameful.

In very informal writing, texting, or social media, you may often see boşver as one word.

But for learners, the safer standard form is:

• boş ver
• dictionary form: boş vermek

So yes, boşver exists in casual writing, but boş ver is the better form to learn and use in normal writing.
