May be a subset words and grammar of english with very few new additions if required, can itself be used as a DSL for many domains? For that matter any language with some of these tests predefined and identifying needed qualities?
The reason is, when I find these minute discoveries matching with known (even for creation - there is already a nasadeeya sukta in Indian philosophy. I guess similar ones should be there in philosophies originated at different places as well) embedded in the language, may be yet unknown might have been handled and more than that it is human spoken language and potential for more long lasting success if we can get a proper DSL out of it is more.
Was there any research in this direction?
