Learn Turkish: Her ne kadar kombi iyi çalışmıyorsa da yalıtım mükemmel. - Even though the combi boiler is not working well right now, the insulation is perfect.

The phrase her ne kadar means "even though" or "no matter how much." It acts as an intensifier for the concessive conditional structure -(y)sa da (even if / even though). While çalışmıyorsa da alone means "even though it isn't working," adding her ne kadar at the start of the clause makes the contrast with the second half of the sentence much stronger.

Can you break down the suffixes used in çalışmıyorsa?

It is built on the verb root çalış (work). We add -mı (the negative marker -ma, which narrows to -mı before the next suffix), then -yor (present continuous), and finally -sa (conditional). Literally, this creates "if it is not currently working." Paired with the separate particle da, it forms the "even though" meaning.

Why isn't there a verb at the end of the sentence (yalıtım mükemmel)?

In Turkish, the "to be" verb is often implied in the present tense for third-person subjects. Yalıtım mükemmel translates directly to "the insulation (is) perfect." You could add the copula suffix -dir to make it mükemmeldir, which would make it sound slightly more formal or definitive, but in everyday speech, it is completely natural to leave it off.

What exactly is a kombi? Is it just a general word for a heater?
