It seems extremely unlikely to me that it wouldn't. I conjecture that no such word exists in any widely used human language. This would be a word who's meaning is not contained in the span of meanings of all other words in the language.
Can you think of one in english (or your native language)? You won't find it in any dictionary, since all those words have descriptions in terms of other words.
The example I've been thinking about was 'pain', which, according to Wikipedia, is "an unpleasant sensory and emotional experience associated with actual or potential tissue damage."
The native Dutch word "Gezelligheid" has no direct English translation and thus apparently has a wiki page in English [0]. Now I wonder what the relevance is of the distance between word vectors from different languages relating to nearly the same concept (e.g Gezelligheid to Cozyness)
I'm amazed that what the paper shows even works.
