"Solresol, the creation of a French musician named Jean-François Sudre, was among the first of these universal languages to gain popular attention. It had only seven syllables: Do, Re, Mi, Fa, So, La, and Si. Words could be sung, or performed on a violin. Or, since the language could also be translated into the seven colors of the rainbow, sentences could be woven into a textile as a stream of colors."
I was thinking about the non-verbal Autists. We need to create a non-verbal language they can communicate with, and this might be of some use.
"A professor of linguistics, Dr. Suzette Haden, created Láadan to test the idea that human languages are not adequate for female expression and Western natural languages may be better suited for expressing the views of men than women. One goal was to determine if development of a language aimed at expressing the views of women would shape a culture.
Laadan is designed to allow people to express things in words which in English can only be conveyed by body language or tone. So, for example, a sentence might contain a special word that indicates that the whole sentence is meant to be a warning. Láadan contains a number of words that are used to make unambiguous statements that include how one feels about what one is saying. there are separate names for an emotion that means ‘happiness for a good reason’ and one that means ‘happiness for no reason’, and a single word for expressing the feeling of ‘I’m angry for a reason but nothing can be done about it.’"
Extremely minimalist but cute little language - totally possible to learn in a couple of days, but has some difficulties in using :-D
