The language contains a mixture of symbols recognizable and unknown, with no dedicated punctuation. Instead, letter symbols are adapted to suggest punctuation or pronunciation. The language also contains not only dipthongs, sounds formed by the combination of two vowels, but also triphthongs, quadriphthongs and even quintiphthongs. Dr. Cheshire explains that these are, somewhat counterintuitively, used to abbreviate phonetic parts of words. Notably, the language is entirely lacking capital letters.
