(Lieven, 11/07/2016 ): Note the difference between three words conventionally translated as wrong. muj is "be incorrect, factually wrong", waS is "be amiss, awry" (something has gone wrong, this didn't turn out according to plan), and QIH is "mistreat" ["wrong, treat unjustly" in KGT].

Missing from EK side of TKD.

Antonyms: lugh

The below is an except from a longer text that is available under the lugh entry. 

Asked: In the meantime: is muj (be wrong) simply the opposite of lugh, and does it work the same way?

Yes. But, when referring to behavior, lughbe' is more common than muj.

Asked: Could one say leQ muj vI'uy "I clicked the wrong switch"?

See above. This would be leQ mItbe' vI'uy.

Asked: If "the victor is not right", is it the same to say lughbe' and muj? 

MO: Yes. But, as noted above, lughbe' is more common.
