Rëra has their own dialect but do not have their script. According to the folktale the written script were given to the ancestor of the Rëra during the time of creation. The said written script was apparently written on the hide or skin of the animal but the same hide was eaten up by the forefather. Hence, written script could not be brought back.
Since there is no written script many words are on the verge of extinction. The terms such as scientific terms, technical terms and other recent origin words are not found in our dialect since these words were not used during those days e.g. satellite is recent origin which word is not found in Rëra dialect. But some of the new words have also been originated on the basis their appearance and the nature of their use.
