Those concerned about the compression of our sped-up language are directed to “Linguistic Ruin? LOL! Instant Messaging and Teen Language,” by Sali Tagliamonte and Derek Denis, an article in the spring 2008 quarterly “American Speech” (dukeupress.edu).

(Oxford University Press, $30). She’s a scholar who can write in real time with real words.
