    Isn't "grammar" a perfect tag for this question? The reference to the other question was fine. We don't need to edit this much. Oct 5 '16 at 6:00

If you want something with the same idea of surprise of Kio la fek and with similar intensity and vulgarity, go with Kio(n) feke ...

  • Kio feke ...
  • Kio feke estas
  • Kio feke okazas
  • Kio feke estas tio
  • Kion feke vi manĝas

Kio(n) feke ... has the same amount of syllables than Kio la fek, and has avantages. One, it is more grammaticaly correct, Two, it is easy to modulate. You can create variations depending on the intensity and the source of the surprise.


The expression "WTF" as independent expression is an english or even american idiom, which is unusual in other languages I know. If you want it as a part in a sentence

What the f**k are you talking about?

you could say

Pri kio, damne, vi parolas?

    You are correct that it is an idiom, but still languages have means to express something like that (I can immediately think of the Bulgarian equivalent expression). I think I've actually seen damne used, and it is a good suggestion. Thanks for the answer! I'll wait to see if people come up with other alternatives. :) Sep 20 '16 at 10:37

    I like to add -aĉ- in there too: “pri kio vi damne parolaĉas” :)

It seems to me that "fek" was chosen - as an anglicism - because it sounds like the third word in WTF. I've been swearing in Esperanto since before WTF was a thing, and I always swear on the devil (or the beard of Zamenhof.)

  • Kio diable estas tio?
  • Je la barbo, kion vi faras?

    Haha, I really like the beard "option". :) Sep 20 '16 at 11:52
  • Is 'Kio, diable?' a valid WTF alternative? I like the rhythm.
