Summary: As the previous GeoCurrents post pointed out, languages often borrow words from one another. But just as this process is ubiquitous, it often becomes ideologically and politically fraught. Politicians and bureaucrats—though typically not the ordinary speakers of a language—often feel that foreign words violate the purity of their language..While this proposed ban may seem farcical to some people, especially given the failure of previous such attempts (as discussed below), the real reasons behind it are much deeper and more sinister than may appear.
