Mersi is a loanword from French[1], it&#x27;s also used in the adjacent country of Armenia.<p>The Proto-Indo-European root for &quot;no&quot; is *ne, so many (most?) IE languages feature this. e.g. no, non, nyet, nein, ne, na, ni, etc. There are languages from India to Ireland that have this sort of negation.
