Let's look at the sentence "It's not it"
In Hebrew it's "זה לא זה" (lit. it no it)
In French C'est n'est pas ca
In all the languages I'm familiar with, in order to say "It's not it", one needs at leat three words - one specifying the object we're talking about, another word in order to specify the object we compare with, and at least one word to make the negative predicate happen. Obviously different languages may decorate these three words with more words, because the grammatical construct requires it (just like in French)
My question is : is there a language where we can say "it's not it" with less than three words?
