Editing Lapine language (section)

==Usage outside the novel==
The use of Lapine outside of the fictional world of the novels has been explored by Thomas E. Murray, who notes that the Lapine word "silflay" (meaning "To go above ground to feed. Literally, to feed outside."<ref name=adams2005-2/>) has entered the English lexicon as more than a mere [[nonce word]]. In a survey Murray found that the term was in use (meaning "the act of rabbits eating above-ground") primarily in the [[Midwestern United States|Midwest and North Central United States]]. He also noted differing levels of use according to [[socioeconomic status]] with usage highest among [[Middle class|middle]] and [[lower middle class]] speakers.<ref name=murray/> Murray suggests that the geographical spread of the term may in part be limited by interactions with rabbits, highlighting the comment of a [[New York City]]-based survey participant who knew the word but never used it due to the lack of rabbits in the city. Murray also claims that the Lapine word "Crixa" (meaning "The center of Efrafa, at the crossing point of two bridle paths"<ref name=adams2005-2/>) has also gained usage outside the novel: it is used by students to refer to the residential dormitories within [[Ohio State University]].<ref name=murray/>

Lapine has been described as easy to learn due to its emphasis on nouns,<ref name=jensen/> and it has been praised as a didactic tool for budding linguists and learners of [[English as a second language]].<ref name=oltermann/>
