in the audio why does the the χ sounds like an f
It sounds OK to me, i.e. not like an f.
It sounds like an f to me too, on both normal and slow speeds
I translated: What is often? This was not accepted. I think that often and frequent are synonyms, don't you?
In terms of usage, often is not really used any more as an adjective; it's an adverb.
A bizarre English sentence in any case - and I agree with Liesz: if you´re going to translate it ´often´ is as good as ´frequent´.
a very strange question in English, unless asking what 'frequent' actually means, or you have not heard what someone has said 'is frequent'. What circumstances would it be used in Greek?
I concur. How do you use this enigmatic question in Greek?
The latter. The former would be Τι σημαίνει "συχνό";.
