In an Aug. 7 post on Quartz, linguist Gretchen McCulloch talks about how young women are the ones who change English the most. Among other examples, McCulloch cites a linguistic study from the University of Helsinki that found that female letter-writers changed their writing faster than male letter-writers. The study looked at 6,000 personal letters written between 1417 and 1681. “Young women’s speech isn’t just acceptable — it’s revolutionary,” said McCulloch.
