Here are two good articles and an excellent — and fun — video perfect for teaching/learning about language in IB Theory of Knowledge classes:
The Science Behind Teenager Grunts, Ughs and Duhs is from Smithsonian Magazine.
They’re, Like, Way Ahead of the Linguistic Currrrve is from The New York Times.
Thanks for sharing! I recognized a lot of the phonetic sounds as ones my 13 year old sister frequently makes. I also appreciated the article; I think people take for granted how much culture and specifically linguistics are influenced by young people.
