Language of Communication (The Trellis)
The Language of Communication is an interspecies auxiliary language in Jörg Rhiemeier's hard SF universe The Trellis. It is used by the members of the Trellis for interspecies communication. The language is often named Loc or less commonly Trellisese by humans. Loc is a logical language that exists only in digital form.
Loc has no spoken form; it is a purely digital language. The "phonemes" of the language are bit quartets; all 16 quartets are used. Each species uses their own characters to transcribe these bit quartets; humans use hexadecimal digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F) which are used to transcribe the language here.
Loc morphology is self-segregating. The length of a morpheme, measured in bit quartets, is equal to the number of consecutive 1s at the start of the morpheme plus 1. So a morpheme starting with a 0 bit is 1 bit quartet long, one starting with 10 is 2 bit quartets long, one starting with 110 is 3 bit quartets long, etc.
Loc has a very productive mechanism for creating systematic names for stars, planets, biological species and other things, as necessary for a society that knows thousands of worlds and millions of lifeforms, and is constantly discovering more. Prominent celestial bodies, species etc. receive "trivial names" which are usually of descriptive nature. For example, humans are known by a name that translates as "furheads", and Earth is accordingly named "Furhead Prime".
