Lapine_ the Luvun

Lapine is a fictional language created by author Richard Adams for his 1972 novel Watership Down, where it is spoken by rabbit characters. The language was again used in Adams' 1996 sequel, Tales from Watership Down, and has appeared in both the film and television adaptations. The fragments of language presented by Adams consist of a few dozen distinct words, and are chiefly used for the naming of rabbits, their mythological characters, and objects in their world. The name "Lapine" comes from the French word for rabbit, lapin, and can also be used to describe rabbit society.

History
The words of the Lapine language were developed by Adams piecemeal and organically as required by the circumstances of the plot. In a Reddit "Ask Me Anything" interview, Adams noted that "I just constructed Lapine as I went - when the rabbits needed a word for something so did I." Reflecting on his inspirations for the words, Adams stated that "some of them are onomatopoeic like hrududu (motor vehicle), but overall they simply came from my subconscious". Adams commented that the motivation for the sound of Lapine was that it should sound "wuffy, fluffy" as in the word "Efrafa". Writing for The Guardian, Keren Levy described the Lapine language as "somehow easy to accept as [a language] we have always known. It is the language of the countryside, of its copses and beeches and of the weather."

Linguistic analyses
Adams includes a glossary of all Lapine words in the book at the end. Notable traits include the plural marker -il (which replaces a final vowel if it is present in the singular: hrududu, "automobile", pl. hrududil), and the fact that cardinal numbers only go up to four, with any number above that being called hrair, "many", although the runt Hrairoo's name is translated into English as "Fiver" instead. The use of Lapine words is often (although not exclusively) used to indicate concepts unique to rabbits, such as silflay (aboveground grazing) or tharn(tonic immobility).

When speaking to other animals (other than rabbit), the rabbits adopt a lingua franca known as "Hedgerow." However, in both examples given in the book (i.e. the mouse and Kehaar the gull) the conversation reverts to Lapine once initial contact has been established. More specifically, the rabbits adopt formal Lapine and the other animals employ a Lapine Foreigner Talkthat Corder describes as "a reduced code or incipient pidgin".
