Having different words for different concepts is great, but creating a new vocabulary will not be enough. There needs to be some training to make people use the words correctly. Otherwise they will just use the new words incorrectly.
Yes, a language is more than just vocabulary.
Getting enough training will be especially important for a conlang
Duolingo style training could file that role well.
Apart from that the quality of the textbook for the a conlang is vitally important for it. It has to showcase the features of the new language.
I'm working on a conlang (constructed language) and would like some input from the Less Wrong community. One of the goals is to investigate the old Sapir-Whorf hypothesis regarding language affecting cognition. Does anyone here have any ideas regarding linguistic mechanisms that would encourage more rational thinking, apart from those that are present in the oft-discussed conlangs e-prime, loglan, and its offshoot lojban? Or perhaps mechanisms that are used in one of those conlangs, but might be buried too deeply for a person such as myself, who only has superficial knowledge about them, to have recognized? Any input is welcomed, from other conlangs to crazy ideas.
