Su taşınca mutfağı temizliyorum.

It’s a converb (adverbial verb form) that most commonly means when / once / whenever / if something happens.

• Su taşınca = when/whenever the water overflows (often a repeated situation)
• It can also feel conditional in context: if the water overflows (then…)

So taşınca is not a full finite verb like taştı (it overflowed); it’s more like overflowing/once it overflows used to set the time/condition for the main clause.

Both exist, but they’re not the same:

• Su taşınca: focuses on the moment it overflows / once it overflows (trigger event)
• Su taşarken: means while it is overflowing (ongoing simultaneous action)

So your sentence frames cleaning as a response that happens after/once overflow occurs, not necessarily during the overflow.

The dictionary form is taşmak = to overflow.

Formation:

• verb stem: taş-
• converb suffix: -ınca (chosen by vowel harmony) → taşınca

Vowel harmony here selects -ınca because the last vowel in taş- is a (a back vowel).

Temizliyorum is literally I am cleaning (right now / around now), but in Turkish it can also be used for habitual or repeated situations, depending on context.

That said:

• Su taşınca mutfağı temizlerim. often sounds more like a general rule / habit: Whenever the water overflows, I clean the kitchen.
• Su taşınca mutfağı temizliyorum. can sound like: When it overflows, I (end up) cleaning the kitchen (these days / typically), or it may feel more immediate/complaint-like in some contexts.

Both can be correct; temizlerim is often the default for a timeless habit.

That -ı is the accusative case (definite direct object marker).

• mutfak = kitchen
• mutfağı = the kitchen (as the specific object being cleaned)

Because temizlemek usually takes a direct object, Turkish often marks it as definite with the accusative.

Two common changes happen:

1) k → ğ softening (in many words when a vowel-initial suffix is added)

• mutfak + -ı → mutfağı

2) The final consonant becomes a soft ğ, which typically lengthens the preceding vowel rather than sounding like a strong consonant.

So it’s a normal sound/spelling alternation: mutfak → mutfağı.

Turkish usually drops subject pronouns because the verb ending shows the person.

• temizliyor-um = I am cleaning / I clean (in this context)

So ben (I) is optional and would usually be added only for emphasis or contrast:

• Ben su taşınca mutfağı temizliyorum. = I (as opposed to someone else) clean the kitchen…

Turkish doesn’t have articles like a/the, and it often uses bare nouns.

• Su can mean water in general or the water in a given situation. Context decides.

So Su taşınca can be understood as:

• When water overflows (general)
• When the water overflows (a specific situation, like the sink water)

Yes. Turkish word order is flexible because case endings show grammatical roles.

Common options:

• Su taşınca mutfağı temizliyorum. (very neutral)
• Mutfağı su taşınca temizliyorum. (more focus on the kitchen)
• Su taşınca temizliyorum mutfağı. (possible, but sounds more marked/emphatic)

The most typical pattern is: (time/condition) + object + verb.

-ınca is primarily when/once/whenever/if, not plain “because.”

If you want explicit because, you’d typically use:

• Su taştığı için mutfağı temizliyorum. = Because the water overflowed/overflows, I clean the kitchen.
• Su taştığı için mutfağı temizledim. = Because the water overflowed, I cleaned the kitchen.

So:

• Su taşınca… = when/if/once it overflows…
• Su taştığı için… = because it overflowed…
