Što se mene tiče, možemo vratiti povratnu čašu.

It means as far as I'm concerned or for my part.

This is a very common Croatian expression used to give your personal opinion or say that something is fine with you.

A more literal breakdown would be something like as for what concerns me, but in normal English you would usually translate it idiomatically:

• Što se mene tiče, ... = As far as I'm concerned, ...

Yes, što often means what, but in this fixed expression it is part of the phrase što se ... tiče.

So learners should treat što se tiče as one useful chunk meaning:

• as for
• regarding
• when it comes to

For example:

• Što se mene tiče = as far as I'm concerned
• Što se vremena tiče = as for the weather / regarding the weather

Because the verb involved is ticati se, which is a reflexive verb meaning to concern or to have to do with.

So:

• ticati se = to concern
• tiče se = concerns

In this sentence, se is not optional. It is part of the standard expression što se X tiče.

Tiče is the 3rd person singular present form of ticati se.

So literally:

• što se mene tiče = what concerns me

But again, that sounds unnatural in English, so the natural translation is:

• as far as I'm concerned

This is one of those cases where understanding the grammar helps, but translating word for word is not the best approach.

Because the expression što se ... tiče takes the genitive case.

So with personal pronouns, you get forms like:

• mene = me / of me in this structure
• tebe = you
• njega = him
• nje = her
• nas = us

Examples:

• Što se mene tiče = as far as I'm concerned
• Što se tebe tiče = as far as you're concerned

A learner may notice that mene can also be an accusative form in other contexts, but here its role is genitive because of the phrase ticati se.

Because Što se mene tiče is an introductory phrase, and Croatian usually separates that kind of phrase with a comma.

So the structure is:

• Što se mene tiče, = As far as I'm concerned,
• then the main statement follows: možemo vratiti povratnu čašu

The comma works much like in English with expressions such as Personally, ... or As far as I'm concerned, ...

It means we can return.

Breakdown:

• možemo = we can
• vratiti = to return / to give back

So:

• možemo vratiti = we can return

After modal verbs like moći (can / to be able to), Croatian uses the infinitive directly:

• mogu doći = I can come
• možemo vratiti = we can return

This is about aspect, which is very important in Croatian.

• vratiti = perfective
  usually used for a single completed action
• vraćati = imperfective
  used for repeated, ongoing, or habitual action

Here, vratiti povratnu čašu suggests a single concrete action: returning the cup/glass once.

So:

• možemo vratiti povratnu čašu = we can return the returnable cup/glass

If you said vraćati, it would sound more like returning it repeatedly or talking about the process in a more general way.

It means a returnable cup/glass, usually one that you can hand back, often for a deposit.

In many real-life contexts, this might refer to:

• a reusable festival cup
• a deposit cup at an event
• a glass/cup that is meant to be returned

So povratna here means something like:

• returnable
• deposit-based
• meant to be returned

Because this noun phrase is the direct object of vratiti, so it is in the accusative case.

Base form:

• povratna čaša = a returnable cup/glass
  nominative singular

Object form:

• povratnu čašu = a returnable cup/glass
  accusative singular

Both the adjective and noun change because they must agree in:

• gender: feminine
• number: singular
• case: accusative

So:

• povratna → povratnu
• čaša → čašu

Usually čaša means glass or drinking glass, but depending on context it can also refer to a cup, especially in everyday speech about drink containers at events.

So in this sentence, English could translate it as:

• returnable glass
• returnable cup

The best choice depends on the situation. If this is about a festival or market, cup may sound more natural in English.

Because Croatian often leaves out subject pronouns when the verb ending already shows who the subject is.

Here:

• možemo already means we can

So mi (we) is not necessary.

You could say:

• Mi možemo vratiti povratnu čašu

But that would usually add emphasis, like:

• We can return it

Without mi, the sentence sounds more neutral and natural.

Yes. This pattern is very productive:

• Što se tebe tiče = as far as you're concerned
• Što se njega tiče = as far as he's concerned
• Što se Marije tiče = as far as Marija is concerned
• Što se tog problema tiče = as for that problem
• Što se cijene tiče = regarding the price

So a good thing to learn is the full pattern:

što se + genitive + tiče

It is a very useful structure in Croatian for introducing a topic or point of view.
