LOL, OMG and TTYL: parents and teachers worry that teenagers' use of these and other forms of online shorthand is harming their language skills. Perhaps they will take comfort from a study suggesting that instant messaging (IM) actually represents “an expansive new linguistic renaissance."

Sali Tagliamonte and Derek Denis at the University of Toronto, Canada, say teenagers risk the disapproval of their elders if they use slang, and the scorn of their friends if they sound too buttoned-up. But instant messaging allows them to deploy a “robust mix” of colloquial and formal language.

In a paper to be published in the spring 2008 issue of American Speech, the researchers argue that far from ruining teenagers’ ability to communicate, IM lets teenagers show off what they can do with language.
