Languages and/or protocols in which words, symbols or structured groups of words can be read independently of order. Such languages were conceived in order to take advantage of some superior beings or non-sentient systems to process communication units in parallel.
The most inferior languages in this group are generally highly context-bound languages, used only in very specific situations (and thus, the scope of events and information that needs to be expressed are very limited) or some computer protocols. These uses to range from Linear Languages to Context-free Languages, and even Context-sensitive Languages. There are some more complex and evolved languages that has expression power similar to natural languages.
Most forms of meta-idea languages falls in this category, and are beyond lower and even middle transapient comprehension.
