Kristy Beers Fägersten is a linguistics professor at Stockholm's Södertörn University. She's examined the growing phenomenon of English curse words popping up in Sweden by studying Swedish comic strips.
Beers Fägersten explains why swearing is easier in a second language and how a few four-letter English words first entered the Swedish lexicon. She adds that the new forms of cussing shouldn't affect Swedish obscenities.
"I think that the adoption and appropriation of English swear words is having the affect that Swedish swear words are retaining their value," she says.
