Banyodaki fayanslarda biraz kireç var; hafta sonu onları temizleyeceğim.

Because banyodaki means the one(s) in the bathroom and works like an adjective before fayanslar.

It breaks down like this:

• banyo = bathroom
• banyoda = in the bathroom
• banyodaki = the one(s) that are in the bathroom

So:

• banyoda = in the bathroom
• banyodaki fayanslar = the tiles in the bathroom

The suffix -ki often turns a location phrase into something that can describe a noun.

Fayanslarda = on/in the tiles or more naturally on the tiles.

It is built like this:

• fayans = tile
• fayanslar = tiles
• fayanslarda = on/in the tiles

The plural -lar comes before the locative ending -da.

Turkish often uses the locative where English would use on, especially with surfaces:

• duvarda = on the wall
• masada = on the table
• fayanslarda = on the tiles

So even though the suffix is often taught as in/at, in real usage it can also match English on.

In Turkish, var is the normal way to say that something exists or is present.

So:

• kireç var = there is limescale
• su var = there is water
• zaman var = there is time

Turkish does not need a separate verb like English there is here. Var already does that job.

The negative is yok:

• kireç yok = there is no limescale

Biraz means a little, some, or a bit of.

Here kireç is basically a mass noun, so biraz kireç means:

• a little limescale
• some limescale

This is very natural with uncountable things:

• biraz su = a little water
• biraz tuz = a little salt
• biraz zaman = a little time

So biraz kireç var means there is some limescale present, not necessarily a large amount.

Because kireç here is being treated as an uncountable substance, like water or dust in English.

So Turkish normally says:

• kireç var = there is limescale
• not usually kireçler var

You only use plurals when you are thinking of separate countable items or different kinds of things. In this sentence, the idea is simply that limescale is present on the tiles.

Onları means them as a definite direct object.

Here it most naturally refers to the tiles (fayanslar), not to kireç.

So the idea is:

• There is some limescale on the bathroom tiles.
• I will clean them = the tiles.

This is natural because in Turkish, just like in English, you often clean the surface that has the dirt on it.

Structure:

• onlar = they / them
• onları = them (definite direct object)

If the speaker specifically wanted to say I will clean the limescale, they could say something like:

• kireci temizleyeceğim = I will clean the limescale
• onu temizleyeceğim = I will clean it

But onları in this sentence points back to fayanslar.

Because it is the direct object of temizleyeceğim.

Turkish often marks definite direct objects with the accusative ending. With pronouns, this is required.

So:

• onlar = they
• onları = them

Compare:

• Kitap okudum. = I read a book.
• Kitabı okudum. = I read the book.

And with pronouns:

• onu = him / her / it
• onları = them

Since the speaker is talking about specific tiles already mentioned, the object is definite, so onları is exactly what you expect.

Temizleyeceğim means I will clean.

It can be broken down like this:

• temizle- = clean
• -(y)ecek = future tense
• -im = I

So:

• temizle + yecek + im
• temizleyeceğim = I will clean

A couple of useful details:

1. The y appears because the verb stem ends in a vowel.
2. The k in -ecek changes to ğ before the personal ending in standard spelling:
   • -ecek + im → -eceğim

So the final form is temizleyeceğim.

Hafta sonu is a standard time expression meaning at the weekend / on the weekend.

In Turkish, many time expressions can appear without any case ending:

• yarın = tomorrow
• pazartesi = on Monday
• gelecek hafta = next week
• hafta sonu = at the weekend

So:

• Hafta sonu onları temizleyeceğim. = I’ll clean them at the weekend.

By contrast, hafta sonunda usually means at the end of the week more literally.

So the difference is roughly:

• hafta sonu = weekend
• hafta sonunda = at the end of the week

Grammatically, the locative ending often gets taught as in / at / on, depending on context.

With surfaces, Turkish very often uses this same ending where English specifically prefers on.

So:

• duvarda leke var = there is a stain on the wall
• camda iz var = there is a mark on the glass
• fayanslarda kireç var = there is limescale on the tiles

A more explicit version with üzerinde is possible in some contexts:

• fayansların üzerinde kireç var

But fayanslarda kireç var is shorter and very natural.

The semicolon links two closely related statements:

• Banyodaki fayanslarda biraz kireç var
• hafta sonu onları temizleyeceğim

The second clause is a response to the first one: there is limescale, so the speaker will clean the tiles.

In everyday writing, you could also see:

• a full stop
• a comma in less formal writing
• sometimes just two separate sentences

So the semicolon is mainly a punctuation choice showing a close connection between the two ideas.

No, Turkish word order is flexible, although verb-final order is very common.

This sentence is natural because it presents:

1. the setting/topic first: Banyodaki fayanslarda
2. what is there: biraz kireç var
3. then the future action: hafta sonu onları temizleyeceğim

You could move things around for emphasis, for example:

• Onları hafta sonu temizleyeceğim. = It’s them that I’ll clean at the weekend.
• Hafta sonu banyodaki fayansları temizleyeceğim. = At the weekend I’ll clean the bathroom tiles.

So the original order is natural, but not the only possible one.

Yes, absolutely.

That version would mean:

• I’ll clean the bathroom tiles at the weekend.

The difference is mainly in structure and focus:

• Banyodaki fayanslarda biraz kireç var; hafta sonu onları temizleyeceğim.
  • first mentions the problem, then the plan
• Banyodaki fayansları hafta sonu temizleyeceğim.
  • just states the plan directly

So the original sentence is a bit more descriptive and connected: there is limescale, therefore I’ll clean them.

Because Turkish, like English, often avoids repetition by using a pronoun.

So instead of saying:

• hafta sonu banyodaki fayansları temizleyeceğim

the speaker says:

• hafta sonu onları temizleyeceğim

This sounds natural because the listener already knows what them refers to.

It works just like English:

• The tiles have limescale on them. I’ll clean them this weekend.

Repeating the full noun is possible, but using onları is smoother.
