Language is a means to express ideas or emotions. It sets them free from the world in which they roam, i.e. our brain between our ears, inside our skulls.
It could work the other way too. Language being used to create or change ideas.
Which parts of language are more effective for responsive use, and which for transformative use? Or, to try to crystallize the question more intuitively, in the practice of conlanging, which subpractices help us understand responsiveness vs. transformation?
Put in such terms, the question also indicates bidirectional functions (functions effective for expression of previous ideas as well as construction of new ones).
