"The clocks are faulty."

Translation: Az órák rosszak.

[Alkimeer]

How fo you pronounce 'ssz'? Is it just like a normal 'sz' or a 'sh-sz' in Hungarian?

[RyagonIV]

It's a double-sz. So it's pronounced as a long sz.
If you double digraph (and trigraph) letters, you double only the first character: gy - ggy, dz - ddz, zs - zzs, and so on.

Though watch out if it's a compound word like karosszék (from karos + szék). You would pronounce that like s + sz, but since the sibilants are tending to blend together, you end up with a long sz instead.

Nagyon szépen köszönöm!

Why is "Az órák hibás." not correct?

[Abenhakan]

"hibás" singular, "hibásak" plural
