mahangu writes "As an armchair linguist, I recently stumbled upon the T9onym or Tynonym. A new morphological process that has come about as a result of people using the T9 predictive text method for sms messages, the tynonym appears to be in use, at least in the UK. Although there appears to have been a Wikipedia entry on T9onyms at some point, for some reason, it no longer exists. What about you, have you heard people say book for cool, in everyday speech? Will the tynonym become a significant part of conversational speak in the years to come, or will it be just another passing fad?"
