Lake Superior State University on Thursday issued its annual "List of Words Banished from the Queen's English for Mis-use, Over-use and General Uselessness"  and several of the 15 words are much used in academe, including "teachable moment," "app," "friend" (as a verb), "tweet" and "transparent/transparency." Several of the other words relate to the economic downturn and efforts to reverse it. These words include "shovel ready" and "stimulus." Wayne State University Word Warriors project meanwhile has released its annual list  of "expressive words that have fallen out of use and deserve to return to conversation and prose." Among them: antediluvian, festoon, mendacity and unctuous.
