Graphical representation, be it a script or a drawing system may be necessary especially for on-wiki contribution and experimentation.
Though context is an important part of Lllllang, some circumstances warrant a script or other representational system. The Latin alphabet will be used for initial experiments. However some diacritics will eventually be used in whatever representational system is implemented, and equivalent Latin vowels may be used for transcriptional purposes.
Because of the immense reliance on context, word order, and the relative lack of modifier suffixes, (especially possesives and cases,) most sentences are ambiguous unless the situational context can be represented. The most effective method of communication then is necessarily the graphic novel, or comic.
