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.
I think it's evidence that it's not easy for prepositions to get added through natural language evolution. It much easier to add new verbs, adjectives and nouns.
While that's true when it comes to conlang design, if you look at English there's plenty of open space of short words. A lot of two letter combinations that are possible with English phonetics aren't valid English words.
That doesn't necessarily mean there's spare space. You don't want every possible combination of letters to make a word, because then it becomes easier to mishear.
